"Impaired physical performance is a common but not obligate result of
a low carbohydrate diet. Lessons from traditional Inuit culture
indicate that time for adaptation, optimized sodium and potassium
nutriture, and constraint of protein to 15?25 % of daily energy
expenditure allow unimpaired endurance performance despite nutritional
ketosis."
