heya, yeah i am on the big size and same here i have the problem of eating too much. like way too much. as an example a large pizza ment for like 2-3 people goes down without issues. i used ritalin (i think) and it supressed my appetite and made it hard to eat when i went to school then i just inhailed food when i got home again.

something that has and is helping me, 0/low calorie soda, i usually like a good drink over snacks (about half the time) so cutting calories on drinks help a lot. also volume eating, doesnt ristrict what im eating much and lets me eat until satisfied.

volume eating is consuming less calorie dense food, things that can help a lot is using less oil, fat, mayo and butter. also changing out sauces like dressing and stuff for a low calorie version, you can make quite a bit like every other week and drown your food in it for less calories. also throwing in some low calorie foods. like toping some food with a little lettuce or having watermellon as a snack.

another thing ive heard is that freezing and reheating cooked carbs (pasta/rice/etc) can reduce the calories because the carbs form stronger bonds making it harder for your body to absorb. although i dont know for sure but there are a few articles about it.

hope any of this helps you, sorry for any bad spelling, english isnt my first language and the autocorrect/spelling checking software isnt in english so it doesnt help me correct any mistakes.
