Not difficult. 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 feel hungry 30 minutes before the next meal (be sure to feel hungry) 10. Stick to it and you can lose weight.
