@Brian12388 I think that diet sheet you got is for Type 1 diabetics who need carbs to balance the insulin they are taking.
Type 2 diabetics like me do best on low carbs and some of us only eat 1 or 2 meals per day.
For overweight people (or even normal weight ones like me) it makes no sense to eat when you are not hungry. On a Low Carb way of eating I put my T2 diabetes into remission, lost 2 stone in weight and got fat adapted so my body can burn fat stores when it needs to. This means I can go for longer periods without loss of energy and without feeling hungry, so I eat 2 meals per day during the week but only 1 meal per day over the weekends.
