Protein Cycling

Implement this cutting-edge protein strategy for improved muscle gains.


“Take in a gram of protein per pound of bodyweight each day.” That’s the baseline held by the bodybuilding community as the gold standard for muscle growth. In the past few years, some bodybuilders have begun to raise the bar, consuming much more protein than that. Some take in as much as three times the recommendation.

Does increasing your protein

above the baseline result in greater gains in mass? Yes and no. Eating enough protein is a must for growth, and if you eat more than one gram (g) per pound of bodyweight, you’ll certainly cover all your bases, ensuring that you don’t fall short. However, eating more for the sake of it may not be as wise as cycling your intake of protein. This month, I explain how to move your protein around —eating less protein on some days, more on others. This type of “protein cycling” is a great way to stimulate greater protein retention and muscle growth.


Take in the protein baseline amount every day: 1 g per pound of bodyweight.

The typical intake is highly effective at supporting muscle growth for hard-training bodybuilders. When you eat at least 1 g of protein per pound of bodyweight daily (200 g for a 200-pound bodybuilder), you’re supplying your body with sufficient protein to rebuild and repair muscle tissue that has been damaged by training. When you rebuild and repair, the result is obvious —you grow. Regardless of whether you’re training to add mass, dieting for a contest or taking a few weeks off from training, you should strive to take in the baseline recommendation. The exception to this is when you’re following the protein-cycling guidelines explained in this article.


If you think you need 2 g of protein per pound of bodyweight, you would be consuming 400 g of protein a day if you weigh 200 pounds. That’s a lot of chicken, meat and eggs. If you rely on protein powders, that’s a lot of shakes (and gastric distress is one possible outcome of downing too many shakes). I believe that such high daily protein consumption is excessive, although it is common among many of today’s pro bodybuilders. I don’t recommend it because this practice demonstrates a misguided understanding of how muscles grow.

Growth depends on a sufficient

intake of protein — not on boatloads — and it is also correlated with carbohydrate intake. The right combo of carbs and protein tends to promote a musclebuilding state better than a diet overloaded with protein and short on carbs. Those who go heavy on protein usually eat far too few carbohydrates. Regardless of a huge daily intake of protein, shortchanging carbs may prevent the body from growing optimally. Plus, there’s a limit to how much growing a body can do no matter how much protein is consumed. I contend that 2 g of protein per pound of bodyweight daily is far in excess of any bodybuilder’s threshold for growth.


P.W. Lemon, PHD, one of the world’s most reputable protein researchers, has often stated that muscle building occurs with a protein consumption of roughly 0.7 g per pound of bodyweight a day (140 g a day for a 200-pounder). If you consumed less than that on a daily basis, you probably wouldn’t make significant gains. Although 160 g might be enough protein for a 200-pound bodybuilder, FLEX still recommends 200 g for a trainer that size, just to be on the safe side.
