Breastfeeding and Body Composition (Nursing, Lifting, and Fat Loss) | Ep 451

"Just breastfeed and the weight will fall right off." That's what every nursing mother hears. 

And then it's a struggle because of what's going on hormonally while you're producing milk.

Lactation does a few things. It suppresses estrogen to near-menopausal levels, shifts fat storage toward your midsection, and creates anabolic resistance in your muscles, all while burning 350 to 450 extra calories a day. 

One side says don't touch your nutrition until you're done breastfeeding. The other says eat in a deficit and train hard like everyone else. Both are inadequate.

Philip walks through the actual research on calorie restriction during established lactation, including the landmark New England Journal of Medicine study that showed zero effect on infant growth with a moderate deficit. You'll learn what's really happening with your hormones, why protein needs are 50 to 100 percent higher than the RDA suggests, why sleep may matter more for body composition than your nutrition plan, and 3 signs that tell you your approach might be too aggressive.
