Regular vigorous exercise, THC, tasty and easily eaten foods with no offensive textures, throw it down your neck hole somewhat quickly before your stomach can tell you it's full when it's clearly not.

I take medication that severely suppresses my appetite and this works for me. I forgo the THC before breakfast and lunch as I work in medicine, I also just don't want to be high all the time. The first two are usually smaller meals, I try to get at least 500 cals per with high protein then a large meal for dinner.
