Hello Dear
I would suggest you to have healthy diet like fresh fruits, green vegetables, milk, curd ,paneer, nuts, eggs etc. Avoid sugar, rice, junk food.Our bodies store any extra water in the body; this includes the cheek and face. So take 2 to 3 liters water in a day. I am sharing a exercise which you can fo easily do at home for this you have take a balloon and blow some air into it. Keep blowing for at least ten seconds. While you do this, you will feel your cheek muscles stretch. Next, allow the air to escape from the balloon, and repeat this step five to ten times. You should be able to see a difference in your face within a couple of weeks.And another exercise is push your tongue out and try to touch your nose with it. Hold this position for five seconds. Next, try to touch your chin with your tongue for another five seconds. You should repeat this for a total of five to ten times. Chewing gum is an exercise that helps reduce cheek fat. Chew for atleast 15 mins.Sleep atleast 8 hours in day for a healthy life.:)
