Weight cutting

Weight cutting is the practice of fast weight loss prior to a sporting competition. It most frequently happens in order to qualify for a lower weight class (usually in combat sports or rowing, where weight is a significant advantage) or in sports where it is advantageous to weigh as little as possible (most notably equestrian sports). There are two types of weight cutting: one method is to lose weight in the form of fat and muscle in the weeks prior to an event; the other is to lose weight in the form of water in the final days before competition. Common methods to cut weight include restricting food intake, water-loading, and perspiration through exercise, wearing a sweatsuit, and/or sitting in a sauna.[1]

Nutritional experts rarely give advice on how to cut weight safely or effectively, and recommend against cutting weight.[2] However, many athletes choose to do it because they wish to gain an advantage in their sport.
