Can you gain weight from sugar alcohol in free gum?

No, you cannot gain weight by consuming sugar alcohol in free gum. Sugar alcohols are a type of carbohydrate that is used as a sugar substitute in many products including free gum. They are not fully digested by the body, so they contain fewer calories than sugar and do not cause blood sugar levels to rise. Unlike regular sugars, sugar alcohols are not metabolised by the body, so they have no effect on body weight or fat gain.
