Postpartum weight loss can be a bit tricky, especially when you are breastfeeding.  While breastfeeding burns about 300-500 calories a day, this is not a time to limit your calories, as dropping below 1,500 calories a day has the potential to decrease a mother's milk supply.  What this means is that a breastfeeding mother needs to net at least 1,500 calories a day, therefore she should aim to eat about 2,000 calories per day to keep a robust milk supply.  Now, when a mother eats these calories, as well as the type of food she eats can make a difference in how those calories are used and burned throughout the day.  My dear friend, Keegan Sheridan, is a naturopathic doctor and author of a fantastic blog at KeeganSheridan.com.  Here is her most recent article about weight loss and eating breakfast for dinner.
