Obesity: Are We Food Obsessed?

By Neuroskeptic | March 24, 2012 9:24 am

According to a Professor Greg Whyte, writing in the Independent, when it comes to obesity, we’ve got an unhealthy obsession with diet. There is –

an incessant diatribe of diet propaganda purporting to possess the panacea for health… [but] the focus on diet linked to the volume and make-up of calories we consume has overshadowed the importance of the critical half of the energy balance equation: physical activity.

Clearly weight is, to a first approximation, a matter of calories in (diet) vs. calories out (physical activity). For any given diet, whether you lose or gain weight is determined by how much exercise you do, and vice versa. There’s no such thing as “overeating” as such, there’s just eating out of proportion to your level of exercise.

But have we forgotten that? Do we talk about the diet side of the equation more? I ran a few searches on PubMed and Google for “obesity” + various other terms to try and find out and it looks like Whyte is right.

See the graph above.

There does seem to be an imbalance, with “food” and “diet” being much more popular than “exercise” and “physical activity”, both in terms of the scientific literature (PubMed), and more generally (Google). This is just a quick analysis of course, but it does suggest that when it comes to weight and obesity, we are more interested in calories in, than calories out.

I wonder why?

    “I wonder why ?”

    Just two passing thoughts:

    So many physicians and researchers have unhealthy sedentary habits. They might prefer not to look too much into it.

    Industrial sponsors might be hoping to make money on “improved food” or “healthy food” like non-organic yogurt in green pots when sport streetwear makes more money that the sport equipement-unless it is a Ferrari of course.
    On the same front, clients will not come and pay a psychologist or a psychiatrist or diabetologist or whatever to learn how to run or swin or play tennis etc…

    Also, sponsors

    Could it be that people who actually research this stuff now know that exercise is comparatively ineffectual compared to diet when reducing obesity? A calorie is not just a calorie.

  • Anonymous

    One opposite example is the television program 'The Biggest Loser' — the contestants are constantly shown exercising, and while they have challenges where they have to show awareness of the calorie content of various foods, we are never told what their daily diet is.

    I am afraid that actually a calorie is just a calorie like an hour is just an hour, a meter or an inch is just a meter or an inch…

    But I see what you meant.Did you noticed therefore what was written in the article NS post is about?

    I cite the article:

    ///Indeed, it appears it is healthier to be “fit and fat” than it is to be “thin and unfit”. Increasing one's physical activity through daily living and exercise has a more positive effect on health than weight loss through diet alone. Furthermore, physical activity is valuable in combating mental health issues such as depression.

    All told, physical activity is the “magic bullet” for health as it targets physical and mental health and, combined with its social benefits, it has the power to truly enhance well-being.///

    But I agree that life is unfair and some genetic studies have shown that -to be concise- a traditionnal full English food diet s' metabolic damages are not reversed equally on everybody with physical exercice.

    Dr Fulli
    I entirely agree with you on the beneficial effects of exercise both physically and mentally, and nothing in my post should be taken as contradictory to that view. I would probably suggest also that regulating the omega 3/omega 6 intake, and increasing the amount of medium chain triglycerides would be good news too, as it would reduce inflammation and increase the bioavailability of ketone bodies for our neuronal metabolism (as you will be aware exercise also increases ketones and reduces inflammation).
    A calorie is indeed a calorie within the context of a closed system, as per the second law of thermodynamics. So if you are counting calories in a laboratory setting, for example measuring the increase in temperature of a fixed volume of water with various fuels then it makes no difference whether that calorie comes from carbohydrate or fat or protein. Similarly in controlled conditions, provided your experimental subjects have their energy input (food) controlled and their outputs (respiration and waste) carefully measured, then again a calorie is a calorie (although there is an energy cost in metabolising protein versus carbohydrates).
    The problem is that outwith a laboratory context the body is not usually seen as a closed system. For people in the outside world different metabolic rates, different levels of insulin sensitivity/resistance, different macronutrient composition and different levels of satiety (resulting from macronutrient composition) all confuse the issue.
    “It is commonly held that “a calorie is a calorie”, i.e. that diets of equal caloric content will result in identical weight change independent of macronutrient composition, and appeal is frequently made to the laws of thermodynamics. We have previously shown that thermodynamics does not support such a view and that diets of different macronutrient content may be expected to induce different changes in body mass. Low carbohydrate diets in particular have claimed a “metabolic advantage” meaning more weight loss than in isocaloric diets of higher carbohydrate content. In this review, for pedagogic clarity, we reframe the theoretical discussion to directly link thermodynamic inefficiency to weight change.”
    “Severely obese subjects with a high prevalence of diabetes or the metabolic syndrome lost more weight during six months on a carbohydrate-restricted diet than on a calorie- and fat-restricted diet, with a relative improvement in insulin sensitivity and triglyceride levels, even after adjustment for the amount of weight lost.”
    But the overall theme from the foregoing for both physical and mental health would appear to be anything which reduces inflammation.
    As an aside, as a psychiatrist I take it you are aware of Dr Emily Dean’s writings in Psychology Today. She posts regularly on issues which cover the above, which may be of interest to you.

    From a sociological perspective, I do wonder if our diets are the main factor in rising rates of obesity. As much as my parents (and grandparents) might like to say that our lifestyles are increasingly sedentary, I don't think intergenerational attitudes towards exercise are all that different over the last 50-60 years.

    But what HAS changed is our diet. Immensely. So from a scientific POV, diet and exercise are two sides of the same coin. But from a historical/cultural/sociological view, our diets are the real catalyst for increasing waist lines in the last 30 years.

  • http://www.blogger.com/profile/05528467206826018008 Jesse Marczyk

    There was a fairly large discussion going on over at Psychology Today not so long ago on the subject:


    The gist of many of the comments seemed to be that it doesn't matter what people eat, weight is weight, always will be, and there's nothing to be done about it. That, and the idea that weight = calories in – calories out was wrong, or too simple. It seemed to be in the service of, essentially, saying that people should not, in any way, be held accountable for their weight.

    As for why they'd focus on food over exercise, that's not immediately obvious, though one solid possibility is they can justify their weight better through that avenue than they can through the exercise route.

  • http://www.blogger.com/profile/07895094545069682233 InBabyAttachMode

    Like Ivana Fulli said, I also think that the obsession with food instead of exercise in the literature may be because the holy grail of the pharmaceutical industry regarding this matter is to find a drug that can treat obesity, by making people eat less (like gastric bypass surgery does, although that effect doesn't last for everybody).
    I also think that once you're morbidly obese it is very hard to start exercising if you don't first lose some weight by dieting.

  • http://www.blogger.com/profile/05609032995818591810 Elliot

    The idea that the energy stored = calories in – calories out is certainly true– what isn't true is that this equation implies that all you have to worry about is calories in – calories out, which is clearly false.

    As a simple example, assume a case where calories out > calories in. The equation will be just as satisfied if the energy removed from storage comes from, among other things, either fat or muscle tissue. Are two diet/exercise regimes equally good if one causes you to lose mostly muscle and one causes you to lose mostly fat?

    It seems rather odd to simply assume that different lifestyle regimes have equivalent effects on these non-caloric differences as long as calories out > calories in. And this is only the first issue with looking at weight gain and loss strictly from the perspective of calories.

  • Left Coast Bernard

    Your weight will certainly go up or down depending upon the balance of calories in and calories out. This is an absolute requirement of the First Law of Thermodynamics or the Conservation of Energy. This law applies to everything, and everything includes organisms.

    Attending to the amount and calorie density in the food you eat keeps track everything on the calories in side.

    Attending to the calories burned during exercise, however, accounts for only about 10% of the calories a typical person uses each day. About 90% of the calories you burn are used for basal metabolism; staying alive while sitting on the sofa watching the telly.

    Carelessly increasing your calorie intake by 5%, munching chips while watching the telly, will require a 50% increase in calories burned during exercise just to maintain your weight.

    Increasing your daily exercise by 10% will only put you 1% out of balance and lead to a slow decrease to a new overall steady state, 1% lower.

    Exercise is important, but it is a small part of our calorie expenditure. The main factor controlling our daily calorie expenditure that is available for us to change is our weight, as our basal metabolic rate is the product of the specific metabolic rate (calories per day per kilogram) and our weight (kilograms).

    Suppose you increase your exercise by 50%. Your weight will gradually decline until your basal metabolic rate has declined by about 5%. There will then be about 5% less of you. If you maintain this new life pattern, your weight will now be stable. If you reward yourself by abandoning your heavy exercise program, your weight will return to its original value.

    The secret to weight control is to pay attention to calories in and calories out, but you must consider all of these calories.

  • Anonymous

    The focus on diet is appropriate. If not for the development of gigantic portion sizes, the ubiquity of calorie dense junk food (which research has shown might have addictive properties), and the shift in social norms that allow people to eat at all times (and in all contexts), there would be no obesity crisis. There is no amount of exercise that can neutralize the enormous amount of calories that people consume today.

    And what about not being obsessed with food and weight but about feeling good and keep using your muscles and also your brain to find interests in life and fun in healthy eating?

  • Ivana Fulli MD

    D Ferguson,

    We are out of topic and you may have discover something to be published.

    I agree with one commentator that very overweight people might benefit from a short strict diet to start a “wellbeing treatment”.

    It is amazing what calory restriction and not taking food at all for a time seems able to do to the human body (fighting cancer, they published, living longer in rats).There is a tradition about that in many culture (a day a month for the Mormons or whatevergiving them better scoring at the “fat lab tests” etc).

    Other than that , as a vegetarian I am disgusted by the four steaks a day diets.

    No good for the planet either to feed and kill so many animals.omg could help there.

    Plus I have seen a case report of health disasters in a french medical journal following Dr Dukan's diet written by an endocrinologist and a judiciary report (TGI Bordeau Mediator case )according to which Dr Dukan himself had prescribed an anorexigen type 2 (Mediator)to a private client- presumably that one could not read the books that make Dr Dukan famous and rich- dyslexia?

    PS:Actually, living without pasta and Italian ice-cream with French sorbet and cake occasionnaly- will not be a life for me and I bet I would be snacking all day long instead of preparing nice pasta for family visit or friends.

    This is interesting topic. I think role of pysical activity in obesity debate should be greater. Benfits of physical activity are impressive no-matter how much (if any)weight loss is achieved. Topic is also discussed in medical journals every once in a while. Look for exemple recent article from Nature Review Cardiology: Olivier L. Charansonney & Jean-Pierre Després 2010. Disease prevention—should we target obesity or sedentary lifestyle? (Behind the paywall)

    Food is everywhere in our culture and we are constantly being reminded by advertisements about nice stuff to eat. If you place an organism in an environment where it is constantly bombarded with stimuli to do something what do you think the mass effect of that will be on a population of organisms?

    There is increasing evidence pointing towards a epigenetic factors playing a role in the obesity problem. Perhaps these are only generational, we cannot yet know.

    There is abundant literature that many chemicals in plastics and food wraps are obesogens. It is another factor in rising obesity and a good reason to stay away from packaged foods.

    There is no single reason for the obesity epidemic. Exercise has been touted but the data on that is not so strong. No amount of exercise will make up for a bad diet.

    Get rid of so many carbs in the diet, we are carb mad and this is contributing to obesity and type 2 diabetes.

    Fasting is a very good idea for health but if you are being persistently bombarded with stimuli to eat … .

  • omg

    Yes ugly paywall for plebs like me not that I'd read it anyway. I could totally live on crackers and diet coke. Plus coffee, water, vitamins, energy shots. That should be our lifestyle. Good old days in the womb when the umbilical cord was all the nutrition we needed. We didn't even need to exercise for 9 months.

  • Ivana Fulli MD

    Hi John,

    A pleasure to read you as usual.

    Weren't you very fond of exercice in your past?

  • http://ironicallyenough.com/ Bryan

    Bernard summed up much of my thinking. However, I think an easy formulation of a key part of it would be this: Between caloric reduction and caloric expenditure, reduction is the low hanging fruit.

    This is because our modern lives are so out of balance in terms of opportunities for each. For example, consider what would it take for you to burn an extra 500 calories. Now compare that to the ease with which you could consume an extra 500 calories.

    I do the daily exercise thing, and lots of it. Over the past few years I’m easily in the top 2% of Americans in terms of caloric expenditure and/or time spent being fully active. Yet even slight bits of carelessness in food or beverage choice can cancel out those numbers and then some.

    When a single common beverage can deliver more calories than most people are capable of burning without significant lifestyle changes, that side of the equation is going to get the majority of the mindshare in this debate.

    I agree that this isn’t ideal, and I am personally a huge advocate of a more active lifestyle. But I can’t deny the stacking of the deck that we all have to deal with.

  • http://www.blogger.com/profile/06647064768789308157 Neuroskeptic

    Thanks for the good comments everyone.

    Bryan: The idea that diet is the low-hanging fruit was what I thought initially as well. But I wonder if it really is? If it's hanging so low, why is it so hard for people to 'pick' it?

    I suppose it's all relative. You might say, not everyone can stick to a diet, but they have even less chance of sticking to an exercise program… but I'm not sure that's true. Certainly it's objectively easier to diet than to exercise, but that doesn't mean it's psychologically easier.

  • DS

    I suspect that talk about diet and dieting is more prevalent than talk about exercise and exercising because one looks kind of silly talking about exercise rather than doing it. Hence Nike's “Just do it”. I don't envision the Broccoli Growers of America starting a “Just eat it” campaign.

  • http://www.blogger.com/profile/17401232760394588049 John

    Hey Ivana,

    I was a the full fitness nut in my younger days but now I wonder if all that exercise has impacted on my longevity. Exercise is clearly very important but once again we turn something into a competitive stressful endeavour and that is supposed to be healthy. Beyond a certain point that is not hard to reach I don't think there are any real benefits to exercise. Endless jogging and gym workouts are more for our vanity than our health.

    A very long time ago I read of a study which claimed that smokers who exercised were in better health than sedentary individuals. True over the short term at least. A recent Australian study has asserted that even if you have good exercise habits sitting down for long periods(say > 1 hour) is an independent risk factor for type 2 diabetes. No-one knows why this is true but I suggest that poor lower leg circulation due to constriction is inducing micro thrombotic events in the lower legs which induce inflammation blah blah blah probably wrong about that. Point is: Get up and walk around at regular intervals, at least every half hour.

    My car died some weeks ago and in the short term I have no intention of replacing it. So I have started walking and the beneficial effects are immediate. I walk fast though but never get anywhere near stretching my cardio and respiratory capacity. I see people running everywhere with their heart meters and their fancy shoes. Tthere is now even a question mark of those shoes, some arguing bare foot running is better bio-mechanically. I just hope they know an orthopedic surgeon in the latter years. Intense exercise is not about health it is about fitness. Two different things.

    What many do not seem to appreciate is that our 3 meals a day cultural imperative may be expanding the stomach beyond healthy limits. A friend and myself have both noticed that we cannot eat the “typical meal” anymore, especially if it is fatty, because we feel full so quickly. We are minimal eaters, only eating not by some cultural imperative but when our body says eat you fool, and even then delaying by several hours. So whereas most people eat by habit we eat by demand. I can't eat a full meal anymore, my stomach must have shrunk so much it protests too much. It is now nothing for me to go a whole day without eating living on coffee and thought. It takes time but I suspect our physiology is trained to expect certain inputs and needs to be retrained. There is even some fascinating research that touches on this at the cellular level. It was found that prolonged fasting causes the mitochondria to fuse and become more efficient. Mitochondria, not external oxidants, are the primary drivers of oxidation events in our bodies so improving mitochondrial function is first and foremost a key strategy against excessive free radical load.

    Stuffing yourself with food all the time not only prevents this mitochondrial fusion, it “clogs up” the cells with detritus. Again, in fasting you find that mTOR collapses and this in turn induces autophagy which is a form of intra-cellular house keeping. This is vital for our health because the build up of detritus(lipofuscin) very much hurts cells. If we are never hungry we are reducing the rate of autophagy. Most animals, or at least predators, go through hungry periods, it appears that evolution has taken advantage of these periods to clean up the house. After all, you don't do housework when you're eating, neither does your body.

    I am now of the opinion that light exercise conducted nearly every day is enough. Preferably aerobic and strength training because of differing physiological benefits from the two. So you could drive to the gym and sweat for an hour or walk into the garden and do some gardening for an hour. Exercise for its own sake? I think that is a big mistake.

  • http://www.blogger.com/profile/08172964121659914379 andrew

    In practice, health care professionals who are in the business of treating obesity tend to be of the opinion that instructions to diet are more effective than instructions to exercise in most patients for weight loss, while exercise is more helpful in maintenance once a goal is obtained.

    This may have as much to do with which behavior is easiest to modify in people who are heavy as a result of their existing habits and the notion that calories are created unequal. Also, most people have limited control over their schedule for a large part of they day (school/work/sleep/travel to and from, etc.) but have relatively more control of what they eat, and heavier people tend to be more sedentary.

    ///one looks kind of silly talking about exercise rather than doing it/// said you.

    Like any psychiatrist's clients, mine have often not being shy about delivering me critics and very sensible ones at times up to the point of hanging off the phone or standing up to leave the room. I do not remenbered thet occuring more often when we talked about exercise though.

    It makes you take interest in their material difficulties like their budget and schedule and in their cognitive problems with motivation and making choices.

    And it shows you care for them but it is time consuming: In the long run it might save time (and money) but you cannot do it within a 20mn session at first.

    (I was blessed of sort doing pro bono for relatively few people taking my time-although it makes me poor and it was fun only as long as it was my choice and not the French Medical Gestapo's).

    PS: Velib is my transport system in Paris and I found a creative way to protect my clothes from the under-saddle disgusting and vexing bike grease (plus my modesty from view when I dress up for some occasion in a nice floating dress). Really funning to look at although my children are not amused.

    Brian, Neuroskeptic and the “low hanging fruit”,

    ///If it's hanging so low, why is it so hard for people to 'pick' it?///

    A concise question smartly and elegantly put in a typical Neuroskeptic way.

    My take on this is that only the rotten fruit are hanging low in our rich but competitive and market driven societies.

    Low hanging fruits -when diet is concerned- are heavy in calories, hyperloaded in toxic additives and light on the wallet
    (fast food, but also heavy loaded in “bad sort of fat” and sugar industrial “sophisticated” food, chocolate bars- you name it

    -in the USA they almost give away for free pork meat and ribs in their supermarkets but to buy a vanilla pod to cook a nice light sauce for scallops or whatever light dessert costs you a patrimony).

    TV and internet seating sessions for hours available 24 hours a day are low hanging fruits too in indefinite supply-when TV used to offer three channels long ago and computer was something I used at work only.

    Plus, life is unfair and exercise is -like religion- something you can discover by yourself but parents have a role- also your school and class mates and partner in life.

    It makes that when exercise is concerned not every young person has the fortune of enjoying a good fruit trees in its garden.

    Last but not least, in the rich societies eating badly and being sedentary are passive decisions when eating sensibly for your health and exercise are active decisions.

    NB: In an African village not overeating and exercising are both passive decisions : women have to do the domestic chores without machines, walk to their plot of farming and cultivate it with an infant to carry on their back and without machinery and seldom get to eat as much as they want…

    Sorry to be a bore but I feel motivated by exercise as a psychiatrist's prescription.

    Diets do not work.
    This is a well proven fact, people who talk about “lifestyle changes” are talking simply talking about life-long diets. That fail the same second you relax.
    Trying to control ones food intake is such a sisyfos project and a good way to keep busy with pointless stuff, staying distracted from the existential questions.

    Look at your cat, he probably relaxes a lot, eats when he wants to, plays when he wants to. Are our brains so much different when it comes to such basic principles as metabolism?
    Stressing an animal will make it eat more, play less and eventually make it obese.

    I recommend to relax, be nonjudgemental to your body, eat what you want (yes, go ahead and eat three packs of Oreo cookies! And then do not judge yourself, it is hard but quite possible), and do what you enjoy doing.

    “Other than that , as a vegetarian I am disgusted by the four steaks a day diets” is a position statement rather than an argument, however I respect that position even if I don't share your revulsion.
    I also agree that modern factory farming techniques can be cruel and unhealthy, and I have grave reservations about the Dukan diet. High protein, low carbs low fat is ironically a high protein high carb diet, as the body creates glucose through gluconeogenesis, and I suspect is basically proinflammatory.
    Time pressures prevent me from looking up the original references, but you may wish to look at points 5 and 8 of Prof Feinman's Blog. http://rdfeinman.wordpress.com/

    To return to topic, hunter-gatherer cultures seemed to do just fine on a moderate protein, high fat, moderate carbohydrate diet (diet as a noun not a verb), and did comparatively little exercise: certainly not exercise for the sake of exercise like modern day gym bunnies.

    Their resistance to the 'diseases of civilisation' seem – at least in part – to be ascribed to their diets (noun) which have a low percentage of grain-based carbs.

    This supports the notion that a focus on diet (as a noun)rather than exercise is more likely to be effective. Don't get me wrong, exercise is good and we should do more of it.

    D Fergusson,

    ///”Other than that , as a vegetarian I am disgusted by the four steaks a day diets” is a position statement rather than an argument (…)///

    I am afraid that a calory is just a calory and “as a vegetarian I am disgusted by the four steaks a day diets” is just the expression of a feeling.

    I reckon that this feeling of mine would makes me unfit to prescribe a four steraks a day diet and that my “political ecological stand” on feeding beefs with cereals will not help. Would it be nice for a client to read disgust on my face or to recognize forced enthousiasm in my voice?

    Lucky me: for now I have never read good science making me feel the urge to prescribe such a diet.
    Of course it might change.

    I agree with Anonymous. The labour saving strategies he speaks about can be thought as ways we have invented to minimize caloric expenditure. We focus on lack of exercise. Electric can openers, electric car windows, snow blowers, elevators etc. The list goes on and on. Calorie out rates are not down because we do not do a regular exercise program. They are down because we have developed ways of doing things as easy as we can.

    I wonder how future generations will see us? In say 200 years from now when there is more people and perhaps food rations, will they look back on images of the obese and think that it was a status symbol of our time?
    I saw a study that showed how obese people get less satisfaction out of eating more food than a thin person does for less, in other words the thin person is mentally satisfied after a small meal, but the big person still feels something is missing on a mental level even after eating more.
    I personally find it very sad to see obese folks say they cannot afford to eat healthy, how can you not afford to eat less? But I think now it is a mind game.
