Can you breastfeed while on an 800 calorie diet?

You can,but the nutritional quality of the milk will not be its best; eating 800 calories a day is considered a starvation diet, this is very wearing and unhealthy for the body. Breast-feeding women should be eating a highly nutritional diet of 1,000 or so calories a day (1,000 calories gives the body just about enough fuel for a whole day). You want to make sure your taking a full multivitamin.

No! A healthy woman should not be consuming less then 1,200 calories a day. And this is if you are very sedetary. If you are nursing, then you have a newborn and chances are you are more active then that. Plus, lactating burns 500 calories a day. So you should be consuming 1,700 calories a day AT THE LEAST. You should continue to take the same vitamin you took during the pregnancy. Even if you consume 1,700 calories a day (which will seem HUGE after living on 800) you will still quickly loose the extra weight you put on during the pregnancy. If you are loosing more then two pounds a week, there is a large chance that the weight will come back on, and you will hit a weight platue. It took you nine months to put on that weight, give yourself time to loose it. You need to take care of a little one, and that baby needs you to be healty.
