A probiotic and a few grams of/soluable fiber/FOS
like inulin, oligofructose, fructooligosaccharides (FOS), galactooligosaccharides (GOS), and other oligosaccharides in my coffee. This tides me over for 3-4 hours, drinking lots of water keeps my belly feeling full.
MAY CAUSE LOTS OF GAS! if you not use to fiber. Start with small amounts
Sometime I eat a tablespoon or 2 of coconut oil. That will usualy add another hour till I'm feeling hungry.
