Sweets are made of pure sugar, meaning they are carbohydrates in their most refined form and have the highest glycemic index (GI). For disciplined athletes who are not diabetic, it’s generally best to avoid sweets.
As harmful as sweets can be for athletes, there are still a few situations where sugar can be used strategically to boost performance. Since sweets are carbohydrates with a very high GI, their energy is absorbed rapidly by the body.
For example:
If you're on a long run and your energy reserves are depleted—to the point that you're feeling weak or dizzy—a quick dose of sugar can give you a fast energy boost and help you continue.
