Personally, I wouldn't. Just eat healthy and exercise regularly. 👌🏾

Cutting your calories will cut your milk supply. You burn 20 calories for every oz you make. So if your baby is eating 20-40 oz a day that is an additional 400-800 calories a day on top of a normal 1200 calorie diet. If you are wanting to lose weight just keep nursing and eating as much as you can but eat healthy foods. Like snack on nuts. Eat salads. Etc.

From my own personal experience I couldn't. It caused my daughter to lose weight and I wasn't producing what they call high fat milk anymore. I had to stop drinking them and start a high fat diet to get her back on track.
