A study in the Nutrition journal aimed at determining the relationship between caffeine intake and ketogenic (low-carbohydrate) exercise allows for a decrease in glycogen and ammonemia, which can impair body function The caffeine group showed a significant decrease (up to 25% ) in blood ammonia 60, 90, and 120 minutes after the start of exercise compared with the placebo group. The researchers concluded that caffeine consumption may reduce the amount of ammonemia that occurs during exercise.
