I believe in health at every size this far--even if weight loss is for some reason very difficult, there are still often things that can be done to improve health. And for a lot of people, a low carb diet or paleo etc. can give health improvements (or at least things that will lead to better health) immediately--lower or even normalized blood glucose, lower insulin, lower blood pressure, improved blood lipids, before much if any weight has been lost. But saying that increased body fat in and of itself can't have some direct adverse effects on health really just isn't true.

Anti-cravings... alcohol becomes sort of yucky when I go more keto, I get a real aversion to it.
