I highly recommend NOT starving yourself. You can stuff yourself with loads of fresh fruit and vegetables and not gain weight. You will feel better for it. Limit or avoid meat, eggs, milk, and refined foods and beverages that contain lots of syrup and sugar. Seriously, you have no reason whatsoever to go around hungry. I've been vegetarian since early January. I weigh 132 lbs. (I'm 5' 7"). My blood glucose is normal, and my blood pressure has dropped from 140/90 to 120/80. I have oatmeal or cream of wheat with cinnamon and raisins for breakfast. I eat bananas as a mid morning snack. Lunch is usually peanut butter on whole grain bread, but today I had homemade tamales. For dinner I made a black bean burger with fresh bakery bread, tomato, onion, mushroom, light mayo, chunky mild salsa and a side of potato slices. With a little planning you can eat well and lose weight. Set aside time for exercise too.
