Many small meals is best for me but then I have to watch that they don't turn into many large meals!!! I should say I have been diagnosed hypoglycemic.
OK so realistically tho I eat 3 main meals (ideally protein and veg tho Ezkiel English muffin or oatmeal for breakfast works) with a whole bunch of small snacks (fruit, nuts, cheese stick, leftovers, etc.) That seems to be doable and good for me and when I plan my meals and stick to it, I lose. No sugar, lowish carb, not too crazy on the dairy. Occasional treats like pizza or dessert (best for me: sugar free dessert like sf cookies or chocolate.)
