@GoodBoyUV I think it's even simpler than that. Just have protein in every meal.
Protein is the biggest of the 3 macronutrients that blunts hunger, even higher than fat and your body doesn't store protein. It just uses it in 2 days time.

Eating more slowly also helps since it takes about 20 mins for the signal to travel and register in your brain that you are full, but I can argue that's secondary since a lot of the time people eat socially and are chatting while eating, making any meal take longer.
