The Fasting Mimicking Diet and protein

Health Q & A with Dr. Michael Jacobson, D.O.

From the November 2019 issue of Heartfelt Magazine.

Q: In the July 2019 issue of Heartfelt Magazine, you said that protein is one thing that is limited significantly in the Fasting Mimicking Diet. Is that all protein or just animal?

A: The focus, or intent, of the Fasting Mimicking Diet (FMD) is to restrict protein in general. However, meat is nearly all protein (except for fat). Even the most “protein-dense” non-animal foods (beans and peas, i.e. legumes) have less than 20 percent protein, and so are not restricted.

In my book, The Word on Health (Copyright 2000, Moody Press), I included a Relative Food Composition figure (page 87). It’s also included here. Notice that protein is most concentrated in fish and poultry. The difference with red meat, cheese and dairy has more to do with the relative fat content, since most meats are nearly devoid of carbohydrates. Be aware that these are only general approximations. Food composition can vary significantly depending upon how they are produced.
