After meals i feel heavy n lazy.although try to eat good food .i take green tea but that doesn't work either?

See below: That is kind of normal. Try eating smaller meals, more often if need be. Hope this helps.

Overhyped: Green tea is the latest in a long line of overhyped nutritional products. Claims include weight loss, better health, longer life, better endurance. Do not believe the hype. Yes green tea contains some anti-oxidants and phytonutrients, but it still contains caffiene which is a stimulant and has diuretic properties. Too much green tea is not good for you.
