Research summary
Sports nutrition guidelines for carbohydrate intake during exercise are currently generic to people of all body sizes. This is because the present evidence suggests that people of different body sizes display a similar ability to burn ingested carbohydrates during exercise. However, this analysis is based on studies which were not designed to answer this specific question, and may not be able to detect this potential effect.
Our pilot work suggests that body size does affect the ability to burn ingested carbohydrates during exercise, but to be confident that this effect is real, we need to follow this work up with a study specifically designed to answer this question. The aim of this study is to understand if larger people are able to burn more ingested carbohydrate during exercise than smaller people. To answer this question, people who weigh less than 70 kg will be compared to people who weigh more than 80 kg with respect to the rate at which they burn ingested carbohydrate during exercise.
