This has been proven false. People are suffering under this lie and gaining weight because when you eat less, take in less of the nutrients your body needs to survive, your body will go into survival mode, lowering the BMR. And it will start stripping your non-essential parts, such as muscle and bone. And finally, people on extreme low calorie diets can actually gain weight because the body is stressed and conserving anything above its new base needs.
Finally, doctors for >100 years have attributed extreme obesity to the consumption of unnecessary carbohydrates.
LOL. Yeah, right. If I burn more energy than I consume, I'll gain weight. That's why the Americans found loads of overweight concentration camp survivors when they liberated them during WWII.
