Just have breakfast and lunch every day, from two hours after a meal to the next meal, and from two hours after a meal to bedtime, jog or walk at the speed of crossing the road for 30 minutes. Try to eat less dinner. Don't eat too much for the other two meals. It is best to be hungry 10 to 30 minutes before the next meal. Stick to it and you can lose weight. Weight loss training camp doesn't cost money.
