No fast,junk,oily,fried foods. avoid cream based foods on regular basis. fresh vegetables, fruits except banana, coconut dry fruits can help u. most importantly u v to practice body poses/yoga ,2 times early morning walking, skipping, etc Exercises. so plan proper diet as well as Exercises plans.

You need to follow a balanced low carb diet and couple it with regular squat exercises. Follow small quantity frequent feeding eating habit.
