What carbohydrate proportion is described in CrossFit nutrition guidance?

• A. 40% of total calories from low glycemic carbohydrates
• B. 60% from high glycemic carbohydrates
• C. 20% from carbohydrates
• D. Carbohydrates are not specified

Answer: (A)

The main idea this question tests is how CrossFit nutrition frames carbohydrate intake for an active, high‑intensity program: a moderate overall share of calories from carbohydrates, with a emphasis on low glycemic sources to fuel workouts and support steady energy.

Around 40% of total daily calories from low glycemic carbohydrates provides enough glycogen for demanding sessions while minimizing blood sugar spikes that can impair performance and recovery. This approach favors quality carbohydrate choices—like oats, sweet potatoes, legumes, and most fruits—over high glycemic carbs that cause rapid energy swings.

Choosing a much higher proportion from high glycemic carbs would risk energy crashes during workouts, while a very low allocation (like 20%) may not supply sufficient glycogen for intense training. Finally, CrossFit guidance does specify a carbohydrate target, so saying it isn’t specified would be inaccurate.
