I've been on a keto diet for several years now - mostly since an under-5active thyroid makes me sensitive to carbs and I also have been striving to adapt to using fat as my feul sorcerer in my ultramarathon races instead of the ubiquitous carb aid station food.
Today I slapped a load of fatty ribs onto my little grill for a nice lunch before starting another 24 hour fast.
A hot fire = nice grilled meat
I've cut down to pretty much one healthy meal per day with intermittent fasting and the results are good with my reading today being fantastic despite not fasting yesterday.
