       Fats for performance

       Fats
       
       Fat also provides body fuel. For moderate exercise, about half
       of the total energy expenditure is derived from free fatty acid
       metabolism. If the event lasts more than an hour, the body may
       use mostly fats for energy. Using fat as fuel depends on the
       event's duration and the athlete's condition. Trained athletes
       use fat for energy more quickly than untrained athletes.
       Consumption of fat should not fall below 15 percent of total
       energy intake because it may limit performance.  Athletes who
       are under pressures to achieve or maintain a low body weight are
       susceptible to using fat restriction and should be told that
       this will hinder their performance.
       
       Fat may contribute as much as 75 percent of the energy demand
       during prolonged aerobic work in the endurance-trained athlete.
       There is evidence that the rate of fat metabolism may be
       accelerated by ingesting caffeine prior to and during endurance
       performance. However, insomnia, restlessness and ringing of the
       ears can occur with caffeine consumption. Furthermore, caffeine
       acts as a diuretic and athletes want to avoid the need to
       urinate during competition
