The Calorie Debacle – T2D 19

The Calorie Debacle

Eat Less. Cut your calories. Watch your portion size. Those form the foundation of conventional weight loss advice over the last 50 years. And it’s been an utter disaster, perhaps only topped by the nuclear meltdown of Chernobyl. This advice is all based on a false understanding of what causes weight gain.

Why don’t we ever consider the critical question of “What causes obesity?” We believe that we already know the full answer. It seems so obvious, doesn’t it? We think that excessive intake of calories causes obesity. We think that this is a caloric imbalance. Too many ‘calories in’ compared to too few ‘calories out’ leads to weight gain. This Calorie Balance model of obesity has been drilled into us since childhood.

Fat Gained = Calories in – Calories Out

The underlying, unspoken premise is that these are independent variables fully under conscious control. This completely ignores the multiple overlapping hormonal systems that signal hunger and satiety. This further assumes that basal metabolism remains stable and unchanging.

But these assumptions are known to be incorrect. Basal metabolic rate can adjust up or down by forty percent. Restriction of calories invariably leads to a reduction in metabolism, ultimately defeating weight loss efforts.

For the last 50 years, we have unquestioningly followed this ‘Caloric Reduction as Primary’ program. Dietary fat, being high in calories were restricted. We made food guides, food pyramids, and food plates to indoctrinate children into this brand new low-calorie religion. ‘Cut your calories’ was hymn of the day. “Eat Less, Move More!” we chanted.

Nutrition labels were mandated to include calorie counts. Programs and apps were created to more precisely count calories. We invented small appliances like Fitbits to measure exactly how many calories we were burning. Using all of the ingenuity that makes us human, focused like a laser beam, and dogged as a turtle crossing a road, we cut calories. What was the result? Did the problem of obesity simply fade away like the morning mist on a hot summer day?

The results could hardly have been worse if we had tried. The storm of obesity and type 2 diabetes started in the late 1970’s and today, some forty years later, it has become a global Category 5 hurricane, threatening to engulf the entire world.

What went wrong?

Only two possibilities can explain how obesity could spread so rapidly in the face of this shiny new advice to reduce fat and calories. Perhaps the ‘Caloric Reduction as Primary’ advice is simply wrong. The second possibility is that this advice was good, but people simply were not following it. The spirit was willing but the flesh was weak.

This is the game called, “Blame the Victim”. This shifts the blame from the advice giver (the advice is bad) to the advice taker (the advice is good, but you are not following it). Was the entire obesity epidemic simply a sudden, simultaneous, coordinated, worldwide lack of willpower? The world can barely agree upon which side of the road we should drive, but yet, without discussion we all decided to eat more and move less?

By declaring that their scientifically unproven caloric reduction advice was flawless, doctors and nutritionists could conveniently shift the blame from themselves to you. It wasn’t their fault. It was yours. No wonder they loved this game so much! To admit that all their precious theories of obesity were simply incorrect was too psychologically difficult. Yet evidence continued to accumulate that this new caloric restriction strategy was about as useful as comb to a bald man.

The Women’s Health Initiative was the most ambitious, important weight loss study ever done. This enormous randomized trial involving almost 50,000 women evaluated this low-fat, low calorie approach to weight loss. Through intensive counseling, women were persuaded to reduce daily caloric intake by 342 calories and increase exercise by 10%. Calorie counters expected a weight loss of 32 pounds over a single year. This trial was expected to validate conventional nutritional advice.

But when the final results were tallied in 1997, there was only crushing disappointment. Despite good compliance, over 7 years of calorie counting led to virtually no weight loss. Not even a single pound. This study was a stunning and severe rebuke to the Caloric theory of obesity. Reducing calories did not lead to weight loss.

So, there were now two choices. First, we could respect the expensive, hard-won scientific evidence to devise a most robust, more correct theory of obesity. Or, we could simply keep all our convenient, preconceived notions and ignore the science. The second choice involved far less work and far less imagination. So, this groundbreaking study has largely been ignored and relegated to the dustbins of nutritional history. We have been paying the pied piper every since, as the twin epidemics of obesity and type 2 diabetes explode.

Real world studies only served to confirm this stunning fiasco. Conventional dietary treatment of obesity carries an estimated 99.4% failure rate. For morbid obesity, the failure rate is 99.9%. These statistics would not surprise anybody in the diet industry, or even, for that matter, anybody who has ever tried to lose weight.

The Calories In, Calories Out theory had gained widespread acceptance based on its seemingly intuitive truth. However, like a rotting melon, digging past the outer shell reveals the putrid interior. This simplistic formula is riddled with erroneous assumptions.

The most important source of error is that reducing ‘Calories In’ leads to a reduction in metabolic rate, or ‘Calories Out’. A 30% reduction in calorie intake is quickly met with a decrease in basal metabolic rate of 30%. The net result is that no weight is lost.

The other major false assumption is that weight is consciously regulated. But no system in our body is wholly unregulated like that. The thyroid, parathyroid, sympathetic, parasympathetic, respiratory, circulatory, hepatic, renal, gastrointestinal and adrenal systems are all closely controlled by hormones. Body weight and body fat are also strictly regulated. In fact, our bodies contain multiple overlapping systems of body weight control. Body fat, one of the most important determinants of survival in the wild, is not simply left to the vagaries of what we decide to put in our mouths.

Hormones control hunger, telling our body when to eat and when to stop. Ghrelin is a powerful hormone that causes hunger, and cholecystikinin and peptide YY are hormonal satiety signals, which tell us that we are full and should stop eating. Think about the last time you were at the all-you-can-eat buffet. Imagine that you’ve already eaten many heaping platefuls of food, and you are completely, 110% full. Now, could you eat a few more pork chops? Merely the thought might make you nauseous. Satiety hormones are exerting a powerful effect to stop you from eating. Contrary to many popular beliefs, we do not simply continue eating simply because food is available. Calorie consumption is under tight hormonal control.

Studies show that weight loss leads to persistent elevations in ghrelin which leads to increased hunger even 1 year after weight loss. It was simply the loss of willpower, these patients were actually, physically, measurable hungrier.

Hormones also regulate our basal metabolic rate, the baseline level of energy needed to keep our bodies running normally. This is the energy used to generate body heat, to power our heart muscles, our lungs, our liver, our kidneys, etc. Low caloric intake reduces basal metabolic rates as much as 40% in an effort to conserve energy. Deliberate over-feeding increases basal metabolic rates as the body tries to ‘burn’ off the excess energy.

Fat accumulation is really not a problem of energy excess. It’s a problem of energy distribution. Too much energy is diverted to fat production as opposed to, say, increasing, body-heat production. This energy expenditure is controlled hormonally. For example, we cannot decide how much energy to expend on fat accumulation versus new bone formation. Therefore, what is important is how to control the hormonal signals we receive from food, not the total number of calories we eat..

As long as we believed, wrongly, that excessive caloric intake led to obesity, we were doomed to failure. Under this paradigm, 500 calories of brownies is just as fattening as 500 calories of kale salad, a notion that is clearly ridiculous. Blaming the victim turned obesity from a hormonal disorder into a moral failure and excused medical professionals from their botched attempts to treat the obesity epidemic.

We could not ‘decide’ to be less hungry. We could not ‘decide’ to increase basal metabolic rate. If ate less calories, our body simply compensated by decreasing metabolic rate. Different foods evoke different hormonal responses. Some foods were more fattening than others. Calories were not the underlying cause of weight gain. Therefore, reducing calories could not reliably reduce weight.

Obesity is a hormonal, not a caloric imbalance. The hormonal problem was mainly insulin.

We made food guides, food pyramids, and food plates to indoctrinate children into this brand new low-calorie religion.

I’m currently picturing a black pyramid with a ring of children dancing around it, offering plates of the “preferred foods” (the ones pictured on the pyramid) and chanting as they go around and around it–this may be a good opening to some sort of nutritional horror movie. If only Hitchcock were still alive!!

So how come some people can just count calories and eat at a deficient and lose weight while others can’t?
Though some people will weigh and count every little thing and that’s just plain ridiculous. We didn’t’ evolve with calorie tracking apps and weight scales.

David Sandy

Maybe some people are just fat because of traditional reasons. They then lose weight and start blabbering if I can do it anyone can. People with real hormonal issues aren’t going to be part of the successful 1%.
Note almost every story of big weight losses starts with out of control gluttony even exceeding CICO predictions.

Birgit
Guest
David Sandy, I deeply resent your insulting remark stating that out of control gluttony is the cause of big weight gains. I have been dieting all of my life and after losing weight, I always gained it back and then some. I have T2D and have followed Diabetes Association and my dietiticians advice for 15 years. The result? In January of this year I weighed 300 lbs. THIS WAS NOT DUE TO GLUTTONY!!!!! Since I found Dr Fung’s website and have read his books, I have lost over 50 lbs. I follow an LCHF protocol with 15 grams on net… Read more »

I said some not everyone. 3 years ago I weighed 440+ now I weigh 250 and am going lower like it was nothing after I found Dr Fung. However, problems don’t have to be binary. There can be people fat because they are glutton. Then there could be people fat because they need specific advice. There can be a combination of above. Those people are the current success stories and they talk about it with the it worked for me and I was an out of control glutton everyone must be. This provides anecdotal evidence that standard advice givers latch… Read more »

David Sandy, Thanks for your reply. Had I read your other posts, I might not have posted my reply. I congratulate you on your progress. I guess I am overly sensitized by the condescending and disgusted attitude that many people (both lay and professional) have shown towards me over the decades. Feelings of guilt and worthlessness due to a condition that is denied by the medical establishment in Canada are very hard to bear.

Maybe not so much “out of control gluttony”, here in the USA, but victims of fast food, convenience stores, and successful marketing and production of all that swett, good-tasting soda and junk food that swarm our shelves, and that are so cheap that the indigent and less fortunate among us can only afford to feed their families foods that are rife with carbs and sugar.

Reply to Deb Griffith–
These folks within the community you spoke may be poor– but remember Dr Fung debunks the excuses and says everyone can fast. No money? You can still fast. Can’t cook? You can still fast. I doubt Dr Fung would mind if I add; No healthy food available? You can still fast.

I find this thread of comments somewhat amusing, aside from the hurt feelings, of course. I lost about fifteen lbs. with IF alone. And my point in posting is that continuing on this program as far as I am concerned is the liberation, to some extent, from having to eat ONLY “healthy” foods (Although I generally do…). Thus, if I want a fast-food burger, I eat one. Or maybe two, along with large fries and a real sugar-sweetened cola. Or beer. Yes I like the paleo foods as well, but really a big fat burger on occasion is just perfect.… Read more »

Patrick,

Studies have found that for people without insulin resistance, many types of diets are effective. For those with insulin resistance, it’s the low carb-high fat approaches which are effective.

Tale
Guest

One factor among several is that reducing calories will also tend to reduce some of what is hormonally problematic, at least for the short term. For example, if a dieter opts to switch from soda to water as a calorie reduction method, they are also causing a sugar reduction.

I’m one of those who can just count calories, eat at a deficit and lose weight. Must have done it a dozen times, losing the same 20-30 pounds–the number I needed to lose creeping up year after year. A bit over a decade ago, I switched to a low carb diet–and lost 20 easily. The other ten–I still yo-yo a bit, but I’ll trade a 10 pound yo-yo for a 30 pound one any day. Calories in calories out does work, in the extreme–because you can push things past your body’s ability to compensate. But is it worth it? Maintenance… Read more »

I don’t follow a protocol. Strictly determination and willpower and use of intuitive judgment. I don’t calorie count. I do mainly 5-10 fasts as they fit into my schedule. Longest was 20.

Thanks David. I read your blog and found it really inspiring. I agree that it can be very socially awkward to do longer fasts, and there is even a lot of pressure from my family to not do them. My personal record is 96 hours, but I hope to do even longer fasts to reap more of the rewards.

Out of curiosity, do you have any restrictions on the type of foods you eat when not fasting?

David Sandy
Guest

Stevo,

My only hard rule is no sodas or juice. I’ll go into that in depth in a later post. I periodically restricted various things throughout my life and I think it’s led to good habits so I can effectively self manage as long as I fast. (Example I eat small amounts of bread)

The other rule I follow is I eat things that might be bad but I run in through a badness yumminess tradeoff filter. So no cadbury bars only godiva.

ChrisW
Guest

>No one ever started mentioning a metabolic slowdown as a real factor

Not only that, they said that a relatively small caloric deficit (like 500 kcal/day) would *prevent* metabolic slowdown. What are they saying now, or are they just denying?

David Sandy
Guest

Currently CICO proponents seem to have three major narratives they are split between

Pseudoskeptical denial based on “flaws” in the study.
Just not hearing it.

And the major one is now

CICO still works. You just have to eat even less and it’s your own fault you got fat in the first place so you need to suffer and accept the consequences of your past bad behavior. We knew this all along. Why should we spend money trying to fix this problem.

Patrick

Do you have the links to the studies with metabolism and fasting? Fung has so many blog posts it’s hard to find the right one.

Thats fantastic David, congrats! However, I think people still tend to oversimplify this issue, on both sides. In my case, I lost 125 in 16 months. I retired Feb of 2015, long before hearing about Jason Fung. Between Feb 1st and mid June (4 1/2 months) I lost 20lbs for no apparent reason other than, I believe, I retired from a 2+ hr/day commute.

doing HIIT decreases my appetite. seems counterintuitive. what’s the mechanism here?

JohnM
Guest

The decrease is due to the body’s fight or flight reponse shutting down digestion in order to cope with the extreme exertion.

honeycomb
Guest

Karen .. men and women behave differently to HIIT .. as a general rule ..

You fall into the general rule. Women obtain a hunger supression effect .. generally.

Men just the opposite .. again as a general rule.

Because I am carrying around 10% body fat .. I don’t follow the general rule. When I am very lean .. I do follow the general rule. In fact to avoid that I strictly follow the “lean gains” 16 hour fatsing and 8 hour feeding protocol.

Dr. Larry Siders
Guest
Karen, I experience the same decrease in hunger after doing HIIT. My theory is that the HIIT depletes glycogen stores and switches hormones into “fat burning” mode. And after finally reaching “fat burning mode”, hunger fades (hormones that control hunger are adjusting). This theory is supported (at least for me) by the fact that HIIT has less effect on hunger the first day of a fast when glycogen stores are still high enough that the ~250 to 350 calorie HIIT workout doesn’t use up the last of the glycogen stores. AND according to my caliper readings. Fat utilization (and therefore… Read more »

Another brilliant article Dr Fung, I always learn so much from your posts. I can see how hard it must be for doctor’s and dieticians to admit they were wrong and go back to basic training from the likes of your good self but they have a moral obligation to their patients to admit they got it all WRONG as did we all, from being brainwashed by our respective governments.

In previous post Dr. Fung points out that basal metabolic rate is not decreased when a person fasts INTERMITTENTLY. The 40% drop in BMR occurs only over long periods of caloric restriction, as the graph demonstrates, representing the body’s attempt to maintain its original set point.

David Sandy
Guest

Actually,

in extended fasting the calorie restriction doesn’t seem to occur. See Dr. Fung talking about the mad scottsman. The bmr reduction occurs with calorie restriction. Fasting is different.

This also accord with my experience.

Kathy Meyer

Even though I never truly believed CICO, I still blamed myself. One day I decided to start tracking my calories and daily exercise in a tracker. I discovered what I already knew: I was technically running at a deficit every day of my life. I almost always ate below 1500 calories, and did light activity, and still weighed over 250 pounds. So if the CICO theory worked, I shouldn’t even exist! So many of us knew this and did assume we had very slow metabolisms, but just thought if we worked harder or ate less fat and calories, we’d eventually… Read more »

“the hormonal problem was mainly insulin” So what about the recent studies demonstrating the herb Berberine is as effective as Metformin without the side effects? And when synergized with d-limonene provides, in addition to blood sugar reduction, other health benefits.

https://www.ncbi.nlm.nih.gov/pubmed/?term=berberine+and+d-limonene

David
Guest

For all you know this herb affects insulin or the satiety hormones.

Elaine
Guest

I have read berberine is hard on microbiome and a break from it is required along with taking a probiotic, regularly. I have taken in for limited time and have read it is a substitute for metformin, but why take anything if intermediate fasting and LCHF diet can retrain body to not be insulin resistant?

Liliana Diaz
Guest

This makes a lot of sense. I used to be overweight and after loosing the weight my body is extremely sensitive to gain again. I have been on a LCHF regimen for a while but not very successful in loosing the last 15 pounds of extra visceral fat. I know is due to a hormonal imbalance and a decrease basal metabolic rate. I recently incorporated fasting into my routine with the purpose of helping my system to balance the hormones. What do I need to do to increase my basal metabolic rate?

David
Guest

Eat monounsaturated and saturated fasts, and consider heavy weight training and HIIT.

Richard S Stone
Guest
I think what Dr. Fung is suggesting is that you cannot directly control your Basal Metabolic Rate. Instead you can manage it indirectly by fasting. Dr. Fung is not a supporter of the exercise aspect of weight loss, as I see it. The thing to avoid is caloric restriction and continual eating during the day and night. And based on what he has posted I do not think exercise is critical to weight loss or insulin resistance. Still, as I see this, exercise is part of the concept of being fully healthy, and exercise has some effects on mood. You… Read more »
Walt
Guest

Richard, have you read Dr Fung’s new book on Fasting? One question I’ve had for some time is the blurring of LC and VLC. In the Complete Guide to Fasting, it feels like he uses them interchangeably. Perhaps part of the problem is I did Atkins several times in the past and Atkins tends to equate carbs < 10gr/day to be the way to maintain ketogenesis. I've been trying to keep mine, < 30% of calories. I find it ever so confusing. Any thoughts?

Stephen T
Guest

Walt, that seems to be mixing up the amount of calories with the type of calories. Low calories and very low calorie diets can’t work long term. A low carbohydrate way of eat can and does work, but anywhere near 30% carbohydrates wouldn’t be thought by most people to be low carb, although it’s certainly a lot better than the standard diet. I’d say I’m more in the 5% – 10% carb range and it means I’m rarely hungry and sometimes go into ketosis, but it’s not something I concern myself about.

Walt
Guest
Steven, LC and VLC are for low carb and very low carb. So if the current recommendation by, at least MyFitnessPal is for 55% carbs 30 is, by comparison low by about 1/2. Probably an operative question is when talking diets is, is it a Diet or a diet. Strictly speaking a diet is what one eats, period. I believe Diet is a short time adjustment to what one eats but not intended to be a life long thing. To that extent I don’t esp have an issue with Atkins or the 10g or less of carbs short term but… Read more »

Dr. Fung, is it possible to increase one’s basal metabolic rate after decades of yo yo dieting?

Would a combination of LCHF and Fasting be sufficient or are there other methodologies that need to be applied (such as excercise) to increase BMR?

Hi Birgit, I will offer you some hope. There was a study that came out a few months ago studying the Biggest Loser contestants in the US. The study showed that their metabolic rates were significantly lower after several years following the show. On the surface, this seems like a pretty bleak message. However, if you look at their baseline figures, those metabolic rates look pretty good. You cannot tell me that their time on the show was the first diet they had ever tried. Those contestants more than likely were yoyo dieting for years and years prior. During the… Read more »

Perhaps a controversial “Biggest Loser” show is on order. Why not have a CICO vs. LCHF season. Controversy sells. The sheer scandal of the contestant “breaking all the rules” would draw in millions of viewers. I would love to see Dr Fung coaching someone through to not only lose weight–but possibly lose/reduce some medications.
I am envisioning the CICO contestants with crazy non-stop exercise and the LCHF taking wonderfully, relaxing moderate hikes in the woods.
I girl can dream.

Stevo74

I totally agree. It would be fun to watch one group do an extended fast with minimal exercise versus the traditional subway sandwiches and torturous exercise. One group would be up at 5AM to hit the gym, while the other would sleep in, walk downstairs in their robe, and enjoy a cup of black coffee while leisurely watching the morning news on television. 🙂

Despite the fact that I think that the “Blame the Victim” game players are wrong, I understand why they are confused. We separate the objective (insulin, glucose, sugar, obesity, etc.) from the subjective (hunger, anger, fear, etc) so stridently and so strongly that we often fail to understand that they intersect in the human body just as the physical intersects with the spiritual in the human body.

Thank you Richard, Stephen and Andy for your input– I guess I’ll have to wait and see what my body does. IF paired with LCHF really fits my lifestyle–I think I’ll keep things as is until/unless I develop health issues.

I really love Dr.Fungs articles and learn every time new things. But I have one question going on in my mind for long time… If I eat only food that don´t cause Insulin (like fat), and I eat about 5.000 calories per day (I´m a women 46 years old, so no way to use them all for energy). What happens with the more calories (or food)? Do I store them as fat anyway, even if it don´t causes Insulin? Or what happened to this surlpus of energy? (Of course I don´t eat only fat, it´s only a hypothesis)

Stephen T
Guest
Katy, interesting thought. When you’re off the sugar and carb rollercoaster – eating followed by high and then low blood sugar, and eat again – and instead eat a higher fat diet, your body will know when it’s had enough. We have an off switch, which is why we didn’t used to get fat (and no other creature does so). Fat satiates the appetite and refined, or two many, carbs fuells appetite. You can eat almost endlessly on sugar and carbs and I’m sure we’ve all seen it. So, I don’t think you could eat those 5,000 calories of fat.… Read more »
