justinhoward's own diet

aim of this diet is to achieve and maintain Keto-Adaptation, sufficient for a high level of aerobic exercise where the body uses its own fat stores for energy.
No need to add carbs for long duration/endurance exercise

15-20hr or more endurance exercise per week

Keto-Adaption can take 2-4+ weeks to achieve, and exercise during the 1st week-2weeks at least can be challenging. Once adaptation occurs exercise levels maintaining 70-80% Vo2 Max can be sustained for several hours with just water (add sodium and magnesium to avoid cramping if you sweat a lot)

Typically you need to add sodium (1-2 teaspoons to food per day) to the diet to maintain good levels of both sodium and potassium in the blood.
