Here’s What Happened When I Tried Carb-Cycling For A Month!


Ever since cutting carbs became a thing back in the late ’90s, I’ve made it my personal mission to rehab their rep. Apart from the fact that mashed potatoes are the best, cutting out an entire food group has always seemed extreme to me. Plus, as a health and fitness journalist and a certified strength and conditioning specialist, I appreciate that carbs fuel our body for high-intensity exercise, are the prime energy source for our brain and red blood cells, contain heart-healthy fiber, and also pack B vitamins, iron, and other nutrients.

I also recognize that, as a whole, Americans eat far more carbs than we need. The current recommended daily carb intake is 140 grams per day, plus an extra 60 for every hour of intense exercise we do. However, the average American eats roughly 300 grams a day, the majority coming from highly-processed foods like frozen pizza and soda, says Donald K. Layman, Ph.D., professor emeritus of food science and human nutrition at the University of Illinois. Carbs are, first and foremost, fuel, so it really doesn’t make sense to eat a ton of them if we’re not working out consistently.

I’ve always taken a pretty balanced approach to macros, typically eating between 1,800 and 2,000 calories per day, with about 40 percent of those calories coming from carbs, 30 coming from protein, and other 30 coming from fat. (I’m five-foot-two, about 120 pounds, and about 23 percent body fat these days.) That’s about 180 to 200 grams of carbs per day, which is pretty consistent with carb recommendations considering I hit the gym most days.

On days I don’t exercise (usually about two days a week), though, I can be shockingly sedentary. I work from home and my computer sits all of 30 feet from my bedroom… and about 15 from my kitchen. On some of these days, I bank fewer than 1,000 steps—all day.

Realizing that I don’t need nearly as much energy to fuel typing as I do deadlifting, I wondered if I should try carb-cycling, which involves eating different amounts of carbs on different days. Could this approach to eating help me shed fat and build muscle?

I hit up one of my favorite dietitians, Jim White, R.D., a spokesperson for the Academy of Nutrition and Dietetics, to find out. Extreme carb-cycling protocols can cut carbs as low as 50 grams a day on low-carb days, but White (who isn’t a fan of these extreme protocols) proposed I cycle carbs just a little, cutting out just the amount of carbs I’d burn during a workout and need for exercise recovery on those sedentary days.

Here’s what he recommended for me:
