You can eat anything. As long as you have breakfast and lunch every day, from two hours after a meal to the next meal, and from two hours after dinner to bedtime, jog or walk at the speed of crossing the road for 30 minutes. Try to eat as little as possible for dinner. Don't eat too much for the other two meals. It's best to feel hungry (be sure to feel hungry) for 30 minutes before the next meal. Stick to it and you can lose weight.
