Q: Is there a problem with consuming protein shakes for most of my protein intake?
A: Besides the fact that your muscles of mastication will forget how to chew, there are several other problems. If you're drinking nothing but shakes, you're probably forgetting that food contains much more of physiological value than its macronutrient profile. Protein shakes fail to provide fiber, many vitamins and minerals, and other substances that can improve health and performance. Check out Lean Eatin' Part I and Part II for appropriate food lists. In addition, check out some of my Appetite For Construction columns where I discuss fiber and vitamin intake. The other problem with eating nothing but protein shakes is that it's hard to impress women when you invite them over for "dinner" and pull out your crusty blender and whip up a frothy MRP.
