When I got gestational diabetes, I became scrupulous about weighing my food. But after delivery, I got lazy about my own diet. Now I'm back to weighing, measuring, and tracking my food. My life depends on it, and weighing helps. My healthy 19-yr-old son is proof positive!
A tiny and inexpensive set of scales really helped me keep track. And I really do measure out the half cup of rice, the tablespoon of mayonnaise... It keeps me honest! Good luck!
