Mistake #5: Relying too heavily on the number on the scale. It is not the lightest triathlete who performs the best; it’s the strongest, healthiest one who trains consistently without injury or illness. Yes, losing excess body fat will help you improve performance, but constant under-fueling to achieve or maintain a super-lean body will not. Use body weight and body fat measurements as well as power output or other measurable results to best assess your “ideal weight.” Need help? Seek advice from a certified sports dietitian who can test your body fat and resting metabolic rate to help you come up with a smart fueling and weight-loss plan.
