Read labels, and watch YouTube videos to understand how your body responds to food. The more you know, the better you'll behave.

Don't lose weight rapidly, like you've been doing. It will almost always come back because you haven't changed your basic eating habits. What you need to do is quit "dieting" and figure out a healthy meal plan that you can live with that will let you lose the weight more slowly, -- maybe only a pound or two a month. You'll find that you will gradually get used to eating less, but also eating better. When you reach your goal weight, don't go back to your old habits, but increase your food intake enough that your weight stays steady. I lost 55 pounds just this way and have kept it off for 6 or 7 years now. I weigh myself every morning as soon as I get up so that I can catch any significant weight gain before it becomes a problem and do something about it. I enjoy eating now just as much as I ever did, and I also enjoy finally living at a healthy weight.

PS, my husband couldn't help but notice my weight loss success, and decided to on his own to use the same strategy. He dropped around 45 lbs and has also kept them off.

I tried Noom a few years ago and have lost 40 pounds in 3 years. It changed my idea about eating. I used to yoyo the same 30 pounds.

Track and look at macros. Tedious work but good to ID where you can cut. There is no need to cut carbs, just make sure you’re in calorie deficit.

There is no magic bullet (unless you get that injection that everyone in So. Cal. seems to get).

I am in my early 40s and my weight has been creeping up over the past few years. I was really lucky in my 20s and 30s that I could eat pretty much whatever I wanted and stay slim, but that is definitely no longer the case. I seem to have two issues: 1) I eat a lot (like a large volume of food), 2) I am kind of all or nothing, so either I am eating super healthy, or I am off the wagon.

I can lose weight relatively quickly when I do a combo of Keto/IF/calorie counting, but no surprise that after a month or two of extremely healthy and limited eating, I tend to relax a bit and then go too far in the other direction. Unfortunately at this point in my life I need to really restrict carbs and sugar in order to stay slim, so how do I find a way to stick to this long term?

Anyone have advice?
