Most dancers I know wish they had the strength of an iron man in the frame of a runway model. Sounds pretty impossible, right? There’s good news. Soy protein apparently not only helps you lose weight, but also makes sure the weight lost is fat, not muscle. To get technical on you, the isoflavones in soy inhibit the enzyme that helps your body store fat. So you’ll slim down, shedding fat without losing muscle tissue—or strength. Your best bet to add some soy into your diet? Edamame, aka soy beans. One cup has 25 grams of the stuff!
