There are several of us doing the weight loss challenge and each one does what works for them. We don't call it dieting but a change of behavior and life and we give each other encouragement. I lost the first 20 by cutting out all the sugar. That was tough but I got thru it. The last 9 have been thru cutting back the amount I eat at each meal and exercise that I enjoy. I still eat the foods I like just don't make a pig of myself. I don't snack during the day but I have a snack in the evenings. I wake up with stomach cramps if I don't eat something before bed time. You just need to experiment until you find something that works for you.
