bit more complex than this. the types of food you eat can also have a dramatic impact. simple carbs go through you relatively quickly, spike insulin, don't produce leptin, leaving you feeling hungry sooner than if you were to eat an equal number of complex carbs for example. Your
body also needs all 3 macro nutrients to some degree, so even when you're full, your
diet could very well be lacking if you're not eating the proper types of fats, proteins, etc.
But yes, eat when feeling hungry, with good healthy nutritious foods, is a good way to go about it.
