I've bounced back and forth for years. I finally dropped the excess weight (about 60 pounds) and have kept it off with intermittent fasting. I follow a book that my doctor recommended to, The Obesity Code by Jason Fung.

It sounds like an eating disorder. I guess it could be if you do it to excess, but it works for me.

I don't eat breakfast. I don't even put cream in my morning coffee any longer. No calories until the afternoon.

Mid-afternoon I have a small snack. Something high protein, low sugar. Often it's leftovers from last night's dinner. Dinner is normal dinner. I eat healthy, but I'm not weighing my food or counting almonds.

No late-night snacks. I go at least 18 hours, sometimes more, between dinner and the next day's afternoon snack.

A few times a month I do a longer fast of at least 24, sometimes 36 hours (usually from dinner one night to breakfast 2 days later).

Lots of water. Lots of protein. Minimal carbs. I avoid added sugar as much as possible. Black coffee in the morning, sometimes a latte or coffee with cream in the afternoon. I don't count calories at all.

It's not for everybody, but it works great for me.
