I’m breastfeeding my newborn but want to get back into shape. I’ve heard that I shouldn’t lose more than a pound per week or toxins can go into my breast milk. Is this true? —Amanda, Eagle Rock, CA

Sam Page Fitness associate and founder of Maternabliss, ILONA, responds:

“Your body is continually metabolizing and excreting toxins, regardless of dieting. Some of these toxins do indeed get passed through to your baby while breast feeding, along with many powerful GOOD antibodies (that protect your baby’s immune system) as well.

The idea of not losing more than 1lb per week is a good guideline. However, it is just that: a guideline. Unless you are doing extreme dieting, which can cause a significantly increased amount of toxins to be passed along to your baby during breast feeding, I would not worry about this too much.
