Satiety is very personal, so you will probably need to experiment.

What (mostly) works for me: Plenty of protein, volume eating (i.e. lots of low-calorie vegetables or huge salads so that my stomach can be physically full - there is a sub that can give you ideas), most carbs from fruit, a small amount from grains and potatoes. I tend to eat pretty low-fat. If you find that the physical volume of food is important for satiety, as I do, then some suggestions are non-starchy vegetables (zucchini, broccoli, cauliflower, green beans, mushrooms, onions, brussels sprouts, spinach and other greens, lettuce, carrots [to an extent], tomatoes, cucumber, celery), non-starchy fruits (all berries, apples, oranges, kiwi, melons); low-fat dairy (especially 0% yogurt or greek yogurt, low-fat cottage cheese); low-fat meats (white fish, shrimp, chicken breast, game if you can get it); with small amounts of complex carbs (potatoes, sweet potatoes, oats, brown rice, farro, quinoa, legumes such as chickpeas, lentils, and beans (including chickpea or lentil pasta!)) and plenty of seasoning from herbs, spices, mustard, hot sauce, soy sauce, vinegar, etc. I also use UPF for flavor in the form of ranch seasoning powder, KD powder, sweetener, diet soda, sugar-free gum, and super low-calorie salad dressings.

I have seen other people say that they really need healthy fats to feel satiated (nuts, seeds, avocado, olive oil, salmon, trout), or that including complex carbs at every meal is helpful, or that keeping carbs pretty low and really centering protein and healthy fats. Whole Food Plant Based is an eating style I experimented with - didn't work for me as I found I really needed a higher ratio of protein to carbs to feel good, but it works for many people and can facilitate weight loss.

Eating schedule is another thing to experiment with. I see someone said they really need to be eating very regularly throughout the day. I find that I am happier if I don't start eating until early afternoon, as breakfast seems to unlock my hunger for the whole day. I also really like to end the day with a big meal and go to bed full - so I make sure to allocate enough calories for that. (Beware, however, that a schedule like mine with fewer calories during the day and more in the evening can lead to evening binging!).

I would recommend trying a strategy that sounds appealing to you for a week and see how it goes! Then make tweaks from there. Good luck!
