Hence, he argues not that we eat too much and don't exercise enough and therefore get fat, but actually we eat more, move less and have less energy to expend because we are metabolically or hormonally driven to get fat (i.e the arrow is actually the other way round; we our beliefs about causality are wrong).
He argues that all government recommendations are based on association trials, such as the Framingham Heart Study, hence have completely misinterpreted the data.
He also looks at why the obesity epidemic has started- not down to eating more, exercising less, or eating more fat, but actually eating more fast carbs and sugar.
It is also interesting to know his fiercist critics have been funded by General Foods, Coca Cola, and the sugar industry, hence a rather large conflict of interest.
I understand the claim that carbs are a 'moreish' food, and that we eat them, eat too many, get fat and are driven to do less through hormonal changes bought on by the obesity (increased leptin levels but reduced leptin sensitivity, effects on insulin etc and also the increased effort when an obese body does have to move is very offputting to doing exercise).
What the claim doesn't recognise is that it's perfectly easy to become obese on any macro split if you eat too much (any hormonal predisposition that excessive carbs may give you to get fat is equally given by excessive nutrients in non carb diets) - my ex housemate Andy is a good example. Great friend of mine but crap at listening to advice. For the four years i shared with him hardly ever ate a carb - bacon, eggs and sausages for breakfast, grilled chicken for lunch with ketchup & a single slice of bread, mixed grill for dinner would be a typical days feed.
During the time I knew him he went from 12 stone to seventeen stone, and developed high blood pressure and early diabetes symptoms despite a low carb (but high calorie) diet. It took six-twelve months of retraining to eat veg & fiber and control calories to get things back under control. He now eats probably around 40/35/25 C/P/F nicely calorie controlled and is in much better shape.
His example is one of the reasons I get so annoyed when told (almost always by anti carb people) that the single causitive factor of obesity and ill health in the modern diet is the carbohydrate. It isn't. Excessive crappy carbs definitely contibute and are over eaten by mos westeners and are certainly incorrectly pushed as healthy, but its still not down to them alone. My friend Andy was eating the way he did after being convinced of that same untruth about carbs by some retarded 'expert' making very similar claims to the headlines of that book and certain other people we know on various forums.
There can be many positive effects for many people in readjusting macros and altering food choices within those macros, but at the end of the day calories in vs calories out is always a vital consideration, and the most important one. Am convinced that if i were able to eat 50,000 kcals of anything per day it would kill me quick, even if of the most healthy foods you choose to think of.
