What seems to work and make sense --- is that certain ethnicities have naturally more insulin-sensitivity (this can be overly simplified to "resistance to getting fat and diabetes") than others. Africans and Native Americans, for instance, have a short history of carby eating (as little as 150 years in some cases), and that probably explains why they gain weight and become diabetic sooner than Iranians. Insulin sensitivity is also developed in the womb. If mom's insulin resistant, baby tends to be, too. As you age and eat a diet that requires a constant stream of insulin from your pancrease, WHATEVER insulin resistance you had at the beginning of life will decrease. What that insulin resistance IS for anybody is largely unknown without testing. The tests are available and cheap, but people don't do them (for the most part) until they're confirmed diabetics who have to do them or suffer. To test your glucose without being diabetic is to be regarded as a nut-job. Meanwhile we have naturally insulin-resistant people, skinny and all while following (for instance) a vegan diet and using their own success with that as proof that it works for others---without considering the wide range of insulin sensitivities in others. The comment about moderation working for some but not for others seems to be right on the money. You can't accumulate fat in the absence of insulin (Type 1 diabetics, who produce none of it, tend to be skinny, and only aren't skinny when they eat lots of carbs and have to inject lots of insulin to cover them). insulin literally prevents you from burning body fat as fuel. You cannot burn off your buttocks riding tons of miles if you eat carbs to fuel your riding, which is why there are so many relatively heavy megamilers. OF COURSE, one must do what works for one, but the reality seems to be that over time your insulin sensitivity decreases (you become more insulin-resistant, more closer-to-diabetic), and if your carb intake doesn't decrease commensurately, you will get fatter as you age. This may be good news or bad news, but these ideas here are not chock full of nonsense.
