You'd better try not to eat dinner. If you really can't help it, eat less and eat some fruits and vegetables: apples and cucumbers. If you can persist, you may see obvious effects in 10 days. However, if you don't eat at night, it may damage your health. This method is very useful. That's how I cut it down. You may feel uncomfortable if you don't eat at first, but after 7 or 8 days.
