Hi and welcome. I think it certainly has real value for weight loss in terms of insulin levels. Probably for overall metabolic health, too.

I don't believe we evolved to eat all day and night. We're supposed to wake up hungry and have to go kill something. When dietitians came up with this "eat every 3 hours/fuel your metabolism/breakfast is the most important meal of the day" nonsense, that was trouble. To paraphrase Dr Tro Kalayjian, "Time-Restricted Eating used to just be called, 'eating.' "

If I was writing a how-to weight loss and health book, IF would probably be in the middle. Kicking the sugar, grains and seed oils as much as practical would be chapter one. Get your appetite under control, get off the blood sugar roller coaster, and IF will come more naturally, anyway.

Good luck.
