In your nutrition program, we recommend getting most of your protein from poultry, seafood, or plant-based foods (e.g., tofu, beans). However, it’s certainly OK to eat beef occasionally. When you do, choose grass-fed sources and consider non-beef meats as well, such as lamb, buffalo, bison, or venison. Here's why:
In the United States, mass-produced beef comes from cows that are fed mostly grain and soy, a cost-effective diet to promote growth.
A grass-fed diet is closer to what a cow would eat in nature, and leads to meat with a better nutritional profile.
Grass-fed beef usually has less total fat and fewer calories than grain-fed, with more good nutrients like omega-3 fats, CLA, carotenoids, vitamin E, and other antioxidants.
Wild game meats are a good alternative to beef because they are produced on a smaller scale, typically consume a grass diet, and tend to be leaner. Fun fact: Tim Ferris, Joe Rogan, and others at the top of their professional game get most of their meat from wild game - an excellent nutrition strategy if you can make it happen.
Whichever meat you buy, choose a lean cut (at least 90% if ground) and have a 4-ounce portion (about the size of your palm).
