have you tried low or zero carb diets? I have found that I can much more easily go without eating on a high fat high protein diet.
Not a perfect solution, but it beats the heck out of losing control and bingeing on carbs.
Also, IIRC, while fat doesn't produce a ghrelin response, protein still does.
Keto is like some kind of religion with fitness people. My personal opinion is that people use it as an excuse to eat pounds of steak and bacon while virtue signaling that they're being healthy, but clearly some people really do believe it has helped them and who am I to say otherwise? What I can say, is that I certainly didn't see any of its supposed appetite suppressant effects, and there's a way to get there without becoming some kind of dietary zealot.
Anyhow, was just trying to share some knowledge not give advice. Everyone is different when it comes to preferences but the satiating effects of fat and protein are pretty well studied.
