Why do some people lose 50 pounds on a diet while others on the same diet gain a few pounds?  Simple: they don't. You used self-reported results and the fatties LIED about following the diet. That article is total bullshit. Claims that CICO is bullshit because guhnetics/environment/ feelz, then says bariatric surgery is the only way to lose weight. Because the surgery changes your genes, not because it makes you eat less, correct?
