Consensus statements from leading governing bodies generally recommend that carbohydrate quantities should range from 3 to 12 g kg 1 body weight.9 - 10 However, recent work suggests that LCHF diets that raise blood ketone levels can increase
fat oxidation rates and markers of health and exercise performance.11 - 12 In addition to increased fat oxidation, other potential benefits of LCHF eating plans for endurance athletes include improved training and racing energy, lowered incidence of delayed onset of muscle soreness, reductions in exogenous caloric requirements during training and competition, and the reduced incidence of serious gastrointestinal complaints.13 Although nontraditional, an LCHF eating plan approach has been recommended for athletes in a variety of sports for nearly 40 years, 14 and this report is representative of other cases.
There are also increasing numbers of reported performance benefits of lowering dietary carbohydrate.12, 19,20 Phinney et al. 21 showed enhanced

A possible reason for the alleviation of the athlete's symptoms in this case study (gastrointestinal distress, fatigue, hunger, and menstrual complaints) in response to the implementation of the exercise and dietary recommendations may relate to the removal of physiological stress on the HPA axis, stemming largely via the improved whole body
fat oxidation rates.
The reduced exogenous caloric needs may have been due to higher
fat oxidation rates and could have also contributed to improved performance.
