the best way to make it stick is to take it slowly. Become more aware of the food choices you make - a food log is helpful here - without necessarily looking to correct them first. Just note the times when you think about food, the times you're able to eat healthy and smaller portions and the times when it's harder. Then try and inject some alternatives, make healthier options available for yourself at home, and gradually move your food decisions toward more nutritious food and smaller portions of comfort food.

Even then, thinking in nutrition has moved on from eliminating "bad foods" to eating "good foods" first, and finding a level of moderation with less nutritious food that fits with your goals.

"Stop eating" diets and "fast weight loss" as a primary goal are very good ways to sabotage yourself in the long term. The psychological costs of very restrictive diets are real and lead to losing adherence down the road. Maybe it works for some but the more gradual choice-focused approach worked a lot better for me. Just do what you're capable of day to day, always trying to push that needle a little further, and you might be surprised at how fast noticeable progress comes!
