How much carbs your body can handle can depend on your genetics (i.e. how many AMY1 enzyme activators do you have?)… so just because Billy can lose weight on a high-carb/low-fat diet, does not mean I can, for sure. I don’t do well with lots of carbs, at all. But I do need a little… my one slice of bread for breakfast and about a 1/2 cup of rice with dinner is all I need to stave off cravings for crackers in the afternoon.
I do have diabetes in my family, too… so processed carbs and lots of sugar are not something I want to load up on. Doesn’t even appeal to me, so if my body’s not asking for it, I’ll skip it.
