However , there are so many tall claims .
Just imagine , if you eat food containing 2500 k calories and you require only 1000-1500 Kcal , where will this extra calories will go?
This will deposit in the form of fat .
So avoid sweets , oily , greasy , pizza, burgers .
Take low calories food and within six month your weight will reduce .
Hope this will help you.
However , orlistat120 mg two times in day on empty stomach burn extra fat in body.
Good luck.
