Am breastfeeding 2 month baby,on healthy diet plan,but still cant lose enough weight,i work out 3 times weekly,can i take fat burner sup??

Count the calories: "Dieting" is not needed, as long as a breastfeeding woman eats only as many calories as needed to maintain her normal (pre-pregnant) weight. For example, if she was 120 pounds before pregnancy and is now 145 pounds, she should eat merely enough for a 120 lb woman. Her 25 lb excess will be gradually used up in the production of breastmilk (25 ounces of breastmilk contains about 500 calories).
