Here is a method for not counting calories and eating healthily all through your life without feeling hungry.
Divide a not too huge plate (10 inches or even 8 inches) into four.
One fourth put protein, palm of the hand size
One fourth/or about a tablespoonful of complex starchy carb like brown rice. Other examples are a potatoes including skin or sweet potato with skin (boiled or baked).
The other two fourths (i.e the other half) vegetables like spinach broccoli cabbage. Cabbage is often cheap.
Something like lentils has starchy carbohydrate and protein contained in it all in one go. So those could be eaten as half a plate, with vegetables on the other half if you wanted.
Have a few snacks if you are very hungry of something like celery or raw carrot and about a level tablespoon of houmous, you make yourself. A few small pieces of tofu and some green pepper (misshapen are sold 4 for £1 in supermarkets). A tablespoon of ground linseed with warm water and mashed berries. (Cheap frozen summer fruit berries berries come frozen). You could also have some plain non creamy non fatty non-starchy vegetable soup you make yourself to help you feel full - as a filling snack.
Drink water throughout the day.
Have a tablespoon of oil like olive oil or hemp oil or coconut oil per day.
If you long for a treat, have a little of it after you have eaten a proper meal that has protein. Don't let it become a big issue.
Or have a small piece of whole fruit, preferably not too sweet but, if it is, then have very little/ Examples of very sweet fruit would be grapes and bananas. So in that case you might choose 10 grapes, half a small, not too ripe banana as a treat after your meal.
Avoid fruit juice.
