Who needs to avoid Fat Bombs and BPC?

/, How To Lose Weight/Who needs to avoid Fat Bombs and BPC?

Does eating extra fat via Fat Bombs and Bullet Proof Coffee make you fat? Here’s the short answer. Yes and no. If you are slender, then eating fat will not make you fat. If you are obese/ overweight then yes, eating more fat will make you fat. Let me explain. The answer, of course, has nothing to do with calories (an entirely outdated and useless concept) and has everything to do with physiology. Let’s back up a bit.

Under a ketogenic/ Low Carb High Fat diet, people are encourage to eat the large majority of calories as fat. Generally, they should eat real food, until full. Some people have taken this to mean that they should add extra fat to everything they eat – witness the popularity of ‘Fat Bombs’ – treats or foods with very high fat content or Bullet Proof Coffee – coffee with the addition of extra oil (MCT, coconut etc). There has been some people who find this slows down weight loss and others that feel it does not. What’s happening?

Insulin is the major driver of weight gain. When you gain body fat, the body responds by increasing secretion of a hormone called leptin, which tells the body to stop gaining weight. This is a negative feedback loop, designed to prevent us from becoming too fat. This is a survival mechanism because obese animals who cannot move properly will get eaten. This is also one of the reasons why people say “We are genetically programmed to eat everything in front of our face” or “We are programmed to get fat, but food was scarce before” are completely idiotic mistaken. So why doesn’t it work for us?

Insulin and leptin essentially are opposites. One tells our body to store body fat and the other tells it to stop. If we continue to eat fructose, causing insulin resistance and persistently high insulin, then we will also persistently stimulate leptin. Like all hormones, a persistently high hormone level leads to downregulation of hormonal receptors and the development of resistance. So persistently high leptin levels eventually leads to leptin resistance, which is exactly what we see in common obesity. So, lean people are leptin sensitive and obese people are leptin resistant.

Let’s now think about the physiology of eating dietary fat. Remember there are only 2 fuels for the body – you either burn sugar or burn fat. When you eat carbohydrates or excess protein, it goes to the liver, through the portal vein and stimulates insulin, which tells the body to start burning sugar, and store the rest as glycogen or fat. Dietary fat, on the other hand, does no such thing. It is absorbed in the intestines as chylomicrons, goes through the lymphatic system to the thoracic duct and directly into the systemic blood circulation (not the portal circulation of the liver). From there it goes into the fat cells to be stored. In other words, the fat does not affect the liver, and therefore does not need any help from insulin signaling and goes directly into fat stores.

So, doesn’t that mean that eating fat makes you fat? No, no at all. Let’s take the lean person (leptin sensitive) first. Remember the story of Sam Feltham’s 5000 calories/day experiment? He ate an enormous number of calories per day, and still did not gain weight (53% fat, 10% carb). As you eat lots of fat, it will get stored into fat cells, but insulin does not go up. As fat mass goes up, leptin does as well. Since the lean person is sensitive to leptin, he will stop eating in order to let that body weight go back down. If you force-feed him, as Sam did, the metabolism ramps up to burn off those extra calories.

Sam Feltham

Now, the situation for the obese, leptin resistant person. As you eat lots and lots of fat, insulin does not go up. However, that ‘fat bomb’ does indeed go directly into your fat stores. You respond by increasing leptin levels in your blood. But here’s the difference. You body don’t care. It’s resistant to the effects of leptin. So, your metabolism does not go up. Your appetite does not go down. None of the beneficial weight loss effects of eating that ‘fat bomb’ happens. And yes, you will need to eventually burn off that extra fat you’ve taken in.

The practical implication is this. If you are lean and leptin sensitive, then eating more dietary fat, like cheese, will not make you gain weight. However, if you are trying to lose weight, and have some problem with obesity/ insulin/ leptin resistance, then adding extra fat to your meals is NOT a good idea. Once again, you can see that we do not need to go back to that outdated, and useless notion of calories. Obesity is a hormonal, not a caloric imbalance.

What can you do instead? Well, eating more carbs is not a good idea. Neither is eating more protein. Nor is eating more fat. So, what is left? That’s what we call fasting.

At this point, you might worry about nutrient deficiency. That is why so many people talk about nutrient density. How can you get the maximum nutrients for the minimum calories? This is muddled thinking. Why do I care? Ask yourself this – are you worried about treating obesity or nutrient deficiency? If you choose obesity, then worry about obesity. You don’t need more nutrients, you need less. Less of everything.

If you are instead worried about nutrient deficiency, then treat the nutrient deficiency, but let’s be clear – THIS HAS NOTHING TO DO WITH THE TREATMENT OF OBESITY. If you are worried about, say, Vitamin C because you have scurvy, then by all mean, take foods dense with Vitamin C. But it will not make a bit of difference for the treatment of obesity. The issue of obesity and the issue of nutrient deficiency are completely different. Do not confuse the two. I treat obesity, not beriberi disease. So I worry about reversing hyperinsulinemia/ insulin resistance/ leptin resistance. If you are leptin resistant, then no, adding more fat does not make you lose weight. Fat bombs, for you, are not a good idea.

Update:

I think quite a few people misunderstood the point of this post, and think I suggest a low fat diet. No, I suggest eating a low carb, high fat diet until you are full when you eat. This is the point – if you have 2 choices:

A – Eat LCHF until full.

B – Eat LCHF until full, and then eat more butter, oil, BPC and fat bombs

You should choose option A. I would have thought that this is common sense, but apparently, many people choose option B thinking it better.

Dr. Fung, “If you force-feed him, as Sam did, the metabolism ramps up to burn off those extra calories” would then mean that “if you reduce calories, metabolism will slow down” but that is not necessarily a good thing, if that is the case. The increase or decrease of metabolism is directly correlated with ageing. Animals with very fast metabolism live much shorter lives than animals with slower metabolism. Thus, Sam’s 5000 calories, if that increased his metabolism, it also made his life shorter… I think that what is true for burning carbs is not necessarily true for burning fats–but… Read more »

Hi Dr Stanton, Wouldn’t Time and Homeostasis make the difference? Forcing 5000 calories would make most people’s lives shorter if done long term. Reducing calories by means other than fasting does slow down metabolism (otherwise there would be a “Biggest Loser” reunion show) which will almost always fail long term and then you’d be back where you started (fat and living a shorter life). If you get to a point where your fat stores are too low (less than 10% (?)) and you are not taking in enough energy, well yeah, fasting would not probably work out you. I think… Read more »

A question then. How can I tell if I’m Leptin-resistant? Over past 17 weeks or so I’ve reduced weight by 17 kgs and Serum Insulin from 18 mU/L to 12 but have plateaued at 100 kgs. On LCHF managing carbs to ~10g/day and daily fasting avg 18-20 hrs. Looking for answers.

So very true! Sounds like Jack Kruse…I think he made a similar point somewhere on his blog? Similar idea is if you look in the mirror and see excess body fat, then you are leptin resistant.

I’m not sure but I doubt there is a test for something like that, as it’s all going on in your brain and how it reacts to the signal. I’d say if you can easily manage your appetite on a keto diet then you’re probably not leptin resistant. I can only speak from experience. I am pretty sure I am leptin resistant because even after months and months on a keto diet I have a large appetite although my body has plenty of fat that needs to be shed. But hey, great job with your 17kgs! I think it’s completely… Read more »

Go see an endocrinologist and ask for a leptin resistant test

Dr. Nikol Hopkins

There are blood tests that measure leptin. Our medical practice usesTrue Health Diagnostics lab, but Quest and LabCorp also have the markers. Is it worth measuring? I have yet to see a patient that is overweight (and overfat) that does not have a high leptin level. So depending on your insurance and “need to know” it may not be a wise use of money

In his new book the guide to fasting Dr. fung says to switch it up and try a longer fast 42 hours or more to get things started again.

So if I google “what is my BMI” and plug in my stats, I’ll be able to figure out whether or not I’m “leptin-resistant”.

Part of me is like “wow! I didn’t know it was that simple!”. The other part of me is thinking that I should wait a few years to see if the thoughts shared in a blog will bare any proof.

BMI is a poor indicator of anything- it won’t reliably tell you if you’re overweight and certainly won’t tell you if you’re insulin / leptin resistant. One does not need to know one’s BMI to know one is overweight! If you are overweight, and have been for some time, you are likely to have a degree of IR and LR. If you are obese it is almost a certainty. Insulin resistance can be confirmed with blood testing. Leptin resistance is deduced by physiological response: If you lose weight quite easily by fasting / eating less this bodes well; conversely if… Read more »

Spot on, Essexgirl..so often we think that unless something has been on the front page of every newspaper and magazine, it must be a new fad. Yet much of this information has been out there for many years.

Terri

*should have added that even when something is emblazoned on the front of newspapers/magazines we still think of it as ‘new’ and likely just the latest fad diet.

Paul

I think the role leptin plays is reasonably well understood. I don’t think there’s there’s been a lot of progress on reversing or treating the resistance through medication – there’s certainly been a lot of money spent on developing a “cure” though.

Beck
Guest

The problem with BMI is that it’s wrong. A 5’5″ female weighing 185 with a body fat of 30% is obese. However a 6’2″ male weighing 300 with a body fat of 5% would also be considered obese. This is because it ONLY takes into account height and weight. There’s no real science there.

Elias Jones
Guest

BMI is well-known to be useless (or to be kind, misleading), when it comes to athletes with high lean muscle mass and low body fat. For example, an on-line BMI test will typically tell an elite-level powerlifter or gymnast, with less than 8% body fat, than he/she is mildly obese and should consider starting an exercise program at the local gym.

Charlene

DiHof I am not sure I follow your logic of waiting. If you are overweight you should act NOW. This science is all new too me and I worried it was unsafe/snake oil. But, nothing ventured nothing gained (or lost in this case) right?? I started LCHF and IF and lost weight; I also went to my Dr to keep careful track of my lab work. If something was wrong–the red flags would be in my lab results. In my case my lab report numbers improved so well, my Dr said the numbers don’t get much better. Or you can… Read more »

How do I know if I am leptin resistant? One can not fast continuously for more than 21 days, although my maximum is 7 days so far, one has to eat, right? What a leptin resistant person should eat?

Essexgirl
Guest

why can one not fast for more than 21 days?
One can fast for as long as one chooses, or as long as one has stored fat to provide fuel.
The longest recorded fast was 382 days, as cited in the article, and data has been published to the effect that the faster felt well, improved his weight as well as health markers, reduced his risk of disease, and maintained his weight loss afterwards.

Presently I am doing the 8 week Blood Sugar Diet by Dr Mosley.
Dr Fung reviewed it last spring as one of the best and important books:
https://intensivedietarymanagement.com/book-review-8-week-blood-sugar-diet/
Done in short 8 week periods will not have impact on metabolism.
But I am hoping, and from all accounts of ‘success stories’, that my A1C will lower from 6.1 to normal range, below 5.4. When I have lost weight I have lowered my A1C’s. A most welcome benefit

So, in summary, leptin is the hormone that controls the metabolic rate (up or down) so as to maintain a steady state of stored fat? This amount of fat stored is determined by the hypothalamus which has a “set point” that it tries to maintain (homeostasis.) Insulin is the energy storage hormone. So, if insulin is trying to store energy as fat after the glycogen supply is filled to capacity, leptin will increase the metabolic rate to burn off the excess energy (glucose and fat) to avoid exceeding the body’s set point. Am I correct so far? Does this explain… Read more »
Jenny
Guest
Dave, no, leptin does NOT control the metabolic rate. It is thyroid hormone that controls that. Leptin controls your appetite. So if you’re leptin sensitive, when you’ve eaten sufficient calories for your need you will no longer be hungry. If you’re leptin resistant your body won’t recognise when you’ve had enough and you will still be hungry. BTW, if you fast (800 calories a day) for any length of time you will stuff up your thyroid and your metabolic rate will drop. This is the body’s survival mode and disastrous if you want to lose weight.
Manny Gomez
Guest

Calorie Reduction (800 calories a day) = lowering metabolism.
Fasting = Zero Calories.
Intermittent Fasting if done correctly raises metabolism or keeps it the same.

https://intensivedietarymanagement.com/fix-broken-metabolism/

https://intensivedietarymanagement.com/biggest-loser-diet-explained/

Highlights:
Caloric Reduction as Primary strategy puts you into starvation mode.
The key to losing weight in the long term is maintaining basal metabolism, or keeping ‘Calories Out’ high.
Failure rate of Eat Less, Move More is proven to be 99% or so. This remains the diet advice favored by most physicians and dieticians.
Actual starvation (fasting or bariatric surgery) does not put you into starvation mode
Ketogenic diets do not you into starvation mode

This is so interesting! But I’m still confused, especially regarding the thyroid as the metabolism controller. Recently I’ve been reading about fasting, and plan to try some 24 hour fasts. I’m drug induced “hyperthyroid” because I lost my thyroid to cancer three years ago. I take high dose synthroid to stop the communication between my pituitary to any remaining thyroid tissue. I’m thinking that I’m lepton resistant, because I’ve been stalled for over a year on a LCHF diet that I’ve been on for two years. I lost 38 pounds over the first 6 months, I’m now forming dense fat… Read more »

Dr David Ludwig has looked at this extensively at Harvard. The answer is maybe. Maybe for some people sometimes. It’s unclear. The hypothalamic damage that is leptin resistance may not always heal in adults. More research needed. Do your best & hope your body responds.

This has just made me more confused. I am trying to lose weight and following LCHF diet 70% fat, 20-25 carbs, 5% protein, are you saying that the fat percentage should be lowered? If so to what? What would your macros look like with the addition of fasting? How would you combine the two i.e. LCHF/fasting?

Tfisher

well lets look at this. if you are doing a ketogenic diet(20gms carbs/day) and desire to lose body fat……..where do you think you could make up the fat in your LCHF diet???? answer:on your own fat stores. i belong to a group that does nutritional ketosis……specifically for weight loss. Once you reach maintenance, this is where you may increase your fats. Weight loss still has a calorie deficit approach.

Mame
Guest

@annie mac — I think your answer is in your question. 🙂

If what you are currently doing is not working for you eat LCHF but *with* fasting as well. So you may only eat one [or two] meal a day, and that meal would be LCHF. LCHF to keep insulin low and fasting to give your body time to access stored fat.

I have wondered for weeks how on earth I was going to get to using my fat stores if I ate so much fat 3 meals a day.

Reazul
Guest

So on a 24 hour fast with just 1 meal , you are limited to mainly lots of green vegetables (20-25 grams of non-sugar carbs),olive oil, some nuts and maybe slight bit of meat/one egg all totaling not more than 700/800 calories?Right now I am trying to lower my blood glucose level (fasting BG is now consistently between 9/10 or 162/180 , like to lower it to 6 or 108).Approximately how long (days or weeks) will it take to achive the target?

Reazul

Just to add – I just started the fasting & do it everyday until BG comes down.Also on medication – Metformin+Sitagliptin 500/50 twice a day.

Dennie

I am confused now too. What does this mean for our macros? I’m trying to lose weight. 100g fat- 75g protein-25 net carb daily. Does this mean just use fat for satiety?

That is my question too. I’m on a keto diet, 24 hours fasting, and calorie counting for weight loss.

The message here is that if you are obese it is not a good idea to exagerate fat intake / binge on fat, like some people do, thinking that as “fat doesn’t make you fat”, they can eat it without limits…

Plain and simple, exactly this

Stephen Town
Guest
Annie Mac, if you’re eating 25% of your diet in carbohydrates that’s high by LCHF standards and your protein is low at 5%. You won’t burn fat until you’ve used the carbs and your insulin has dropped. I don’t really count, and don’t think people should obsess, but a more typical ratio would be something like 70% fat, 15 – 20% protein and 5 – 10% carb. So, no you’re not eating too much fat, but you are still at the high end in terms of carbs/glucose. That said, most people in the US will be way higher. I believe… Read more »

I’m also confused. I’m now on a strict lchf (20-25 carbs per day) along with daily IF (usually 17-18 hours fasting and 6-7 hour eating window with 2 meals normally). But I can only do this by having coffee with coconut oil in the mornings/early afternoons. I’m not doing excessive cardio like I used to- 2 hours a day); actually I’m not even exercising yet as I’m worried about messing up a good thing.

When I tried KETO for 6 months and stalled I upped my fat to 90% and started gaining weight. Maybe it works for some but the only thing that seems to work for me is the fasting itself.

My personal N=1, testing high on insulin resistance, if my fat falls below 80% of my diet I stall and stop losing. If i increase my fat back to 80%+, I will steadily start to lose again. I also have my best glucose/ketone readings after high fat days. My loss may be slower (54 lbs in 9 months, about 40 left to lose), but I’ll take slow loss over no loss. I tend to stop tracking my food when I get comfortable. Then I stall. Then I start tracking again and find the only thing really changing is my fat.… Read more »

Typo alert:

“If you are lean and leptin resistance, then eating more dietary fat, like cheese, will not make you gain weight.”

I presume the good doctor means “leptin sensitive” instead of “leptin resistance” [sic].

Since the answer is not eat more fat, not eat more carbs and not eat more protein – but just fast. It got me thinking that I can ADF (fast every other day) and eat hamburgers and ice cream every other day too. If only.

Martin Williams

Hello, Steve. You may be aware of it already, but Krista Varady’s EOD partial fast protocol (5-600 calorie allowance during ‘fasting’) permits indiscriminate food choices, since her research found no difference between high- or low-fat eaters’ results for weight loss.

I think the article basically says not to eat extra fat, as in there is no need to be eating fat bombs and BPC in addition to your meals. My day starts with breaking my 12+ hours fast with a cup of BPC. That is my breakfast and if I recall, BPC does NOT break your fast at all since there is no protein, carbs or sugar in it (correct me if I’m wrong). I then eat my normal low carb lunch with some fats, effectively breaking my fast of 16 – 18+ hours (remember I”m under impression that BPC… Read more »

Yes, you are right, it does not break your fast. Well maybe 10% but it’s probably not a big deal.

ChrisW

Well, taking any food at all, including BPC “breaks your fast” by the strict definition, but Dr. Fung allows for it (or low insulinogenic things like bone broth) if you need it to skip meals. You’re still breaking your fast, but you are still getting most of the benefit.

Abi

Blazer, you are right. If we are fat, we don’t need EXTRA fat added to whatever LCHF meals we fit into our fasting schedule. The fat built into the LCHF meal/s is enough and probably more than. For me,I do 24/1 hr OMAD with it being basically a keto meal. I can’t eat more than a smallish serving before the intense urge to ‘not have any more’ kicks in. The sight and smell of food at that point is completely a turn-off. I do worry that the calories in my OMAD would technically put me in the calories restriction camp… Read more »

All of what you’re saying would be true if we ate natural foods while living in the wild. Not if you get your food from a grocery store.

It is true even for people who shop at grocery stores. I personally believe we are supposed to get most of our calories from starch, not fruit, but fruit is a wonderful source of nutrition as well. I enjoy Dr. Fung’s blog for the science, and for comparison purposes, and others may too. There are doctors who are helping people reverse their diabetes left and right (and are successfully eliminating many other health conditions as well including obesity), and are doing it with a high carb (and high nutrition) approach. Even if Dr. Fung disagrees with their method, he can’t… Read more »

What you say is true in its own context. Personally, after revering fm metabolic syndrome in a few months using, fasting, if and low carb, I have gone on to other ways. All independent of medications. I try Nobel prize winner of medicine like dr Louis ignarro on nitric oxide, last year winner on autophagy, previous winner on the fact cancer cells cannot exist in an acidic environment, vitamin k2 and others. I find that it works better and faster.no one has a monopoly on reversing diabetics. It is all about working together in this new frontier. Btw, I agree… Read more »

Sarah, the idea that fruits and vegetables are the healthiest things we can eat is not backed by science. But you can see it for yourself if you look at major nutrition databases and compare nutrients in foods. The push for 5-a-day, 7-a-day, etc. was dreamed up the by the Fruit and Vegetable producers of California at a meeting in 1991. Do the research and see it for yourself. Veggies are certainly wonderful tasting and add nice color to our meals, but they’re not the nutrition bombs we’ve been led to believe, either. Here’s a sample article you can read… Read more »

For people who are metabolically f*cked, eating a diet of 80% carbs is an incredibly stupid thing to do.

Sarah

Not necessarily. A very low-fat, and low glycemic diet, even though relatively high in carbohydrates, would be a very smart thing to consider. You call it stupid, but are you sure? 🙂

Abi

Sarah have you ever been diabetic or insulin resistant? You reversed those conditions with a vlf 80% carb diet?

For me personally, I tried your ideas in general most of my life eating mostly organic from my own garden. I gained 100 pounds in 30 years so you’ll have to forgive me for not buying into it anymore. Fasting and LCHF have been the only things that have kept me from diabetes. I’m definitely insulin resistant and need to reset my body.

Low glycemic doesnt mean low insulin. Its the insulin resistance Dr. is addressing.

Ellen

Cathy

Fruit and carbs are a disaster for diabetics and insulin resistant people. They raise insulin levels, which trigger fat storage and increase hunger. I’m guessing the majority of Dr Fung’s followers fall into those categories, so this is why your high carb, low fat recommendation isn’t being well received. Believe me, pretty much everyone I know I tried low fat high carb–all thru the 80s especially. My family tried it eating unprocessed, natural foods as well. It didn’t work for us or for the rest of the nation either. Probably a great diet for thin people though.

I just need some clarity here. I am hearing that a LCHF way of eating is not good for weight loss if you are already obese? So then should it be low carb, moderate fat and moderate protein? And what is the difference of eating too few calories and going into starvation mode and not eating any calories while fasting for extended periods and not going into starvation mode? And if I am IF and unable to eat an adequate amount of calories in the short window that I am eating in, am I then at risk of my body… Read more »

As I was reading Dr. Fung’s post, your question is what I was thinking still would need clarification for some readers. I think his answer would be that you are ok as long as you aren’t chronically raising insulin while eating low-calorie. That is what actually causes slowed metabolism. If you are eating a satisfactory amount during your eating window, the fact that you aren’t eating outside the window won’t harm you since insulin is low. As for not eating LCHF, I think the key here is that ‘H’ is ‘high’ only in comparison to the carbs. It doesn’t mean… Read more »

This is not exactly a forum for keto.most of dr fung articles are about reversing diabetes, with obesity and ketosis as being secondary benefits. Look at it from this context, and a lot of things will clear up.

If you are only after weight loss, following dr fung will be a little drastic. Keto, dr ornithology, Mediterranean , paler all works. Depends on what you want. To draw fung, weight loss is just a fringe benefit. It is the internal fats in the blood and organs like liver and pancreas that dr fung is single mindedly going after .

Mike

I’m not sure I agree. Obesity is a sign of metabolic syndrome. Where you find obesity you stand a good chance of finding the others, or a risk of finding them in the not too distant future.

Terry teh

Gotta agree with you. But different folks have different needs and varying tolerance.most of dr fung cases are pretty serious. So some may go for ‘easier’ diet.in my experience, most of my friends just wanna lose weight and the girls just wanna weight loss and better skin complexion.

Anyway, I was replying to chrisTine,to put things into context.

Dr Fung states, “If you are instead worried about nutrient deficiency, then treat the nutrient deficiency, but let’s be clear – THIS HAS NOTHING TO DO WITH THE TREATMENT OF OBESITY.”. To me, this is a very odd thing to say. In the 1950’s, not many people were obese, but the reason especially women were not obese was that they chain-smoked constantly, and the smoking suppressed hunger and was a substitute for binge-eating. SUPER, GREAT, NOT OBESE!!! How wonderful! And no doctor or any researcher would say that today. I have had two good friends die of lung cancer; one… Read more »

They ate 3 meals and no snacks usually. Then their last meal tended to be early enough before bed that they had a longer fast before breaking it than we on the standard American diet would manage eating 5, 6, 7 times a day. The key being that on only 3 meals a day and mostly no snacks people in the 50s were keeping their insulin low which is why they were thinner.

Ken Stephens
Guest
I would say that while leptin is an interesting hormone, whether or not you gain weight with eating high fat has much more to do with your insulin levels, which is of course the storage hormone. So high insulin plus high fat means more fat storage. People who eat very low carb diets tend to have more healthy insulin levels so they don’t over store fat, not from carbs by way of lipogenesis, not from the fat either. The more interesting side of this though is why these people can eat gobs of fat and all this fat does not… Read more »

Eating fat while your insulin is high will probably help you put on more weight, but do we know that it causes insulin resistance in humans?

Here’s a question for you: I have had a lot of trouble losing weight. I finally had a consult with the great Dr. Lustig who said I have excess insulin not related to diabetes. His suggestion was low carb, but low carb made me hypoglycemic. Cutting calories and increasing exercise did nothing (even with nutritionist and personal trainer supervision and more than 1,000 cal deficit daily). She experimented with increasing my calories to 2800 cal and I didn’t gain anything either. So, I finally tried Paleo (+dairy). Still watching my macros and calories, I kept them the exact same as… Read more »
Claudia Wheeler

Katie Did, can you explain what your are doing now that is helping you to lose weight? I have a lot of trouble, too. I’m confused on what you did that actuallly worked. You weren’t Paleo before? Do you eat fruit for example, as that is Paleo? You are now keeping fat to 30% and you are at 50% carbs (what kind of carbs?) and you are losing weight like that????
Can you be super clear on what you are doing NOW and are you still losing? THANKS!!

Katie

I don’t eat fruit. I might try to incorporate it when I am happy with my weight. It’s basically paleo plus dairy. I eat a lot of squash and sweet potato for carbs. Lots of greens as well. No grains no added sugar.

Sarah

Dr. Fung, is it counter-productive to take PG-X while fasting to help curb appetite? They’re basically MCT-oil and fibre pills that are supposed to help regulate blood sugar and curb appetite. I’ve been taking them for about 6 months because I’m constantly famished without them, whether or not I’m fasting. During fasts, I drink a ton of water and rich bone broth and I occasionally eat coconut oil, but none of these help me curb my appetite for more than 10 minutes. Because of my hunger, I’ve never been able to fast longer than 3 days, although I’d love to.… Read more »
Stephen T
Guest

Sarah, I drink coconut oil twice a day with salt and I find it does help to curb my appetite. But you must give it at least half an hour to affect your system. Ten minutes is far to short a time to know if something is working.

Since I went LCHF, I have true control over my appetite for the first time in my life. I’ve noticed that I’ve become very carb sensitive and they fuel my appetite.

Stephen T
Guest

Sarah, I should add that I’m much less ambitious about the length of my fasts. I aim for 16 hours four or five times a week. I know some people like the challenge of going longer, but I’m really not sure that we need to go to extremes, unless there is a particular reason. Speaking personally, keeping things going long term is easy for me if I keep my goals realistic.

Sarah
Guest

Thank you for your reply, Steve. I’ve been eating LCHF since 2011, and did notice significant improvements in the beginning. Over the last few years, however, I’ve been steadily gaining more weight and becoming hungrier more often. Wondering if it’s an insulin issue, which is why I’d like to try for a longer-term fast.

Mike
Guest

I think this may address the argument about whether one needs to count calories on keto or not. Some people insist that they do, others do fine on lazy keto. It seems likely that those who do well on lazy keto are less leptin resistant than those who do not.

I’ve found that I’d rather fast longer between meals than count the calories of each meal.

Thanks, Birgit. I, too, find many of the success stories demoralizing, especially since some very bad advice gets mixed in with the good. I reduced carbs & protein, which reduced my bg (I’m T2), but didn’t help that much with my weight. So often I’ve read that I don’t have to count calories & to make low carb work I must eat a lot of fat. I was even scolded on a low carb forum for saying rabbit was good; it’s a lean meat so “forbidden.” However, I’ve come to the conclusion that to see results, I’m going to have… Read more »

I mean he’s saying NOT to add a lot of extra fat either, but def not a low fat way of eating.

Stephen T

A low fat, low calorie diet is one that leaves people hungry and has failed consistently for 40 years. Low carb with a higher fat content should mean you aren’t hungry and allows you to fast to some extent. The low fat diet is a predictable failure. If your blood glucose has improved on low carb, that’s important. You might have to play around with the proportions, but some combination of low carb and fasting is the way to go. As I’ve said elsewhere, I don’t think fasting has to be extreme to help. I usually do 16 hours and… Read more »

I should have said lower fat, as I am still eating some. But if the only way to lose weight is to lower calories, the fat is where they are. I eat fewer than 20g carbs & fast most days from my late lunch to breakfast. But recently (before cutting some of the fat) I’ve been very hungry in the evening & went from an occasional lc snack to almost a meal. That doesn’t help my bg or weight at all. I hate being so hungry, but I guess I’m going to have to live with it until I get… Read more »

If I can only have 20 grams of carbs (80 calories) and 60 grams of protein (240 calories) how could I possibly eat enough calories without added fat/fat bombs. Even eating fatty sausage, bacon and steaks, the fat on my meat is not enough to get me to an acceptable 1600-2000 calories per day. I need 150-175 grams of fat per day to get adequate calories.

Julie

Rats! I thought fat bombs and BPC were a good way to top off the day so I would stay satiated longer.

What about eating too little, starvation mode, and wrecking your metabolism? Is it ok to just eat 1,000 or so calories a day when doing IF 16/8? I have found that I’m just not hungry but have heard and read so many times that you should never eat only 1,000 cals a day. It’s all so confusing. This article really hit home because for a long time I was adding more fat to meet my fat macros for the day even though I wasn’t even hungry. Guess what? I gained weight. Now I have more weight to lose than when… Read more »
Stephen T

Claudia, eating when you’re not hungry makes no sense. The main reason LCHF works is that we’re not hungry, so eat less. Lower carbs means lower insulin when we do eat, and fasting means longer periods without insulin. I don’t know about some of the things you list in your breakfast, but three strawberries isn’t a worry, particularly after a fast. I have full fat yoghurt with 6 – 8 rasperies, usually after 11.00 a.m. I drink some coconut oil every morning and afternoon. It’s easy to obsess needlessly. I’m not overweight, so maybe I have more leeway, but low… Read more »

Thanks Stephen, I appreciate the response. I don’t like to count calories but I do a check in once in awhile to see what I’m eating and where I am. Since I gained weight in the last year, kind of unexpectedly, I recently checked in. I seem to fall around 1,000 calories. Because I have heard so often that you shouldn’t eat so little, I was sometimes making myself eat more even when not hungry. I also had not eaten any fruit (not even a few berries) for many years as I was doing very low carb (and not seeing… Read more »
Stephen T

Claudia, you’re doing very well as far as I can see.

The problem with LCHF and IF is that it’s not as simple a message as “Eat less, move more”, which is dumb but easy to understand. And that’s its appeal. The problem, of course, is that it doesn’t work.

Low carb made me feel much better and put me firmly in control of my appetite. However, fasting made me constipated and I couldn’t get much advice on this, except to drink more water. LCHF + IF involves a bit of awareness and some trial and error.

Claudia Wheeler
Guest

Thanks Stephen. Did fasting the 16/8 way also make you constipated or do you mean when fasting for several days? I would not want to ever get constipated. I only had one bad experience with constipation after the birth of my son and it was a nightmare. I think the fat in LCHF always keeps things regular. And magnesium certainly helps.

Abi
Guest
Claudia,if your body is in fat burning mode instead of sugar burning, then you don’t need to worry about ingesting only 1000 calories. Your body will get the rest of it’s energy needs from your fat stores. Fasting gets you into fat burning fairly quickly so long fasts of multiple days really are not starvation but your body is silently happily burning through its reserves. Just because we can’t see it happening doesn’t mean our only energy is coming from what we eat daily. It comes from what we have already eaten months and years in the past.
Claudia Wheeler
Guest
Thanks Abi. I’ve gone two days now. First day was 16/8 IF and second day I did 18/6. I think I can do either of those fairly easily most days of the week. But, this Sunday, for example, I will be out of the house early and not back until late so I prefer to eat before I leave the house because I have access to better LCHF foods while at home. So, I won’t be able to do the IF that day. I have fasted 3 days other years and lost weight, just a little. I did a cleanse… Read more »

Charlene
Guest
Excellent post Dr Fung. My thoughts are along these lines: if we are switching our bodies from burning sugar to burning fat, then tis best to pull from our fat stores rather than a recently ingested fat bomb. Why would our body take fat out of our fat stores to use for energy if a boatload was just ingested? If I ever get to the point when I want to stop losing weight (cannot imagine that) then fat bombs might be a good idea.

I am a bit skeptical of the whole “eat until you are full” concept. If someone is leptin resistant, then their ability to sense satiety is impaired. Wouldn’t it make sense to monitor and control caloric intake, even in the context of a LCHF/IF approach?

Sue
Guest

I think this is very simple. Follow a low carb high fat diet. Less than 20-30 grams of carbs a day. Moderate your protein. 70 to 80% percent in good fats.

Eat slowly and wait a bit before going up for that 2nd plate. Give your body a chance to recognize it’s full.

Don’t snack.

Drink lots of water.

If you are having a hard time losing weight don’t add or subtract from the food ratio, just fast more.

FAST. That really is the key.

Claudia Wheeler

Hi, Sue, That sounds good. What about when you are done losing? How do you eat then so as not to gain weight? I would think that if you fast a lot, and then stop fasting and just eat every day, you might gain weight. I once did a 500 calorie a day diet, a few years ago, in desperation to lose weight. I lost the weight fairly quickly, went back to eating LCHF (same ratios you suggest above) and slowly gained all the weight back. It’s not like I ate junk or anything; I just went back to LCHF.… Read more »
Sue and Tony
Guest
My opinion on this, based on what I have understood from Dr. Fung’s work is this; eating 500 calories a day sounds too much like calories in calories out which directly impacts your metabolism. When you fast, which mean nothing to eat at all, it actually speeds up your metabolism because your body switches over to feeding off of it’s self therefore you are getting an unlimited amount of “food”. Your growth hormones speed up too. Like I said before, it really is very simple, people (me included at first) seem to need to make it more complicated than it… Read more »

Thanks Sue! It is hard to wrap my head around it! I agree that the 500 calorie thing wasn’t good. I was in desperate mode and I’ve regretted it ever since. I felt that I did damage my metabolism. It’s been years, though, and I do feel my body healed itself somewhat since then. Still, I wonder if by eating so much less on a fasting way of eating–because you are fasting a lot–you are training your body to always eat that amount and when you eat more, you will then gain.

You have to understand when you give your body a “little” food it sends a signal that maybe there isn’t enough food and that sets up a whole hormonal response (that keeps weight on). That’s why it’s so important to eat… Read more »

My apology if the question as already been asked, but I’m a bit confused about this part: ” …therefore does not need any help from insulin signaling and goes directly into fat stores.”
My understanding was that Lipoprotein Lipase(LP) was required to extract fatty acids from all the different transport systems circulating in the blood(chylomicron, VLDL, LDL, HDL…). But…doesn’t low Insulin levels “turn off” LP???
