Wish I could find that study! But it would be an interesting hypothesis to test for: if someone reduced their calorific content too quickly then the body will attempt to compensate when normal eating resumes. Obviously it would need to use animals and a control group but it might be insightful.
There's a natural experiment of sorts in re-feeding people with anorexia. Many people think this is a risky time because they think it's easy for someone to gain wieght too rapidly.
(I'm not talking about the related, but different, "refeeding syndrome" https://en.wikipedia.org/wiki/Refeeding_syndrome)
Very good info, though I honestly don't think it was exactly what I was thinking of. I'll keep looking for that info...
Ever fast? I find fasting extremely effective at reducing my post fast appetite dramatically. In fact, fasting occasionally the only thing that keeps me from gaining more weight, it "resets" my appetite.
It sounds like gradual improvements are the only way to handle weight loss. So it takes time and effort...
