When you’re working out later in the day, have a small snack about an hour before you get started. A sports bar that has 200 calories or less is a good option.
Look for a bar with low-fiber content, ideally 3 grams or less. Too much fiber before a workout can upset your stomach.
On the ingredients list, keep an eye out for sugar alcohols, like sorbitol, xylitol, isomalt, and mannitol. Too much of these ingredients can give you cramps or diarrhea.
