Could it be it’s actually getting “rewarded” with a high carb diet? An “embarrassment of riches” - too much food - is harder to deal with than the unrewarded preparation for carbs that never come?
We’re getting away from things that can be tested by experiment when we talk about justifications. It’s like the “thrifty gene hypothesis” that used to get talked about more than it does now. It said people got fat because we were programmed through ice ages and other threats to store fat whenever possible. The ones who wasted energy and didn’t store fat when times were good died when times were tough. Nice idea, but how can you test that? And then what do you do about it? (obviously, eat keto!)
I’m familiar with Dr. Bikman - at least in the sense that I’ve watched a few of his videos. From what I know, he’s right. As Dr. Fung said, “I can may you fat. I can make anyone fat. I just give you insulin”.
