Is it required that i eat extra calories while breastfeeding if im trying to loose weight? breastfeeding and diet

Not really: "Dieting" is not needed, as long as the 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 just 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).
