Exactly. Despite what My 600 Pound Life wants us to believe, I think many, if not most, of us who are overweight know about portion size, reading labels, and healthy diet. We also knew, long before science confirmed it, that the problem wasn't losing weight, but keeping it off. Now that we understand more about things like the role of hormones like leptin and ghrelin in weight management, we need to get that information out. I think Whitney blaming her inability to maintain weight loss on PCOS is more about not understanding what her body is doing than making excuses.
