Sorry. I ride 20+ miles / day. 5 days / week. Fasting doesn’t work for me.
Your 8 hours of sleep are included into the 24 hours obviously. That’s only 16 hours of not eating. Think of it that way.
Riding what 20 miles a day? Do you mean cycling?
Intermittent fasting works well when exercising. A ketogenic diet replaces carbs with fats and increases stamina and eliminates the crashes due to blood sugar volatility. The incidence of diabetes (and obesity) is directly correlated to the modern high carbohydrate diet promoted by the “experts.”
The other part of our decline is provided by synthetic fats that are touted as “healthy alternatives.” Real fats do not change composition when heated, nor do they contain toxins that destroy internal organs and cause innumerable autoimmune diseases.
Humans were never vegans, nor were they fueled by glucose. All societies knew the energy benefits associated with fats. Nutrient dense real foods are far superior.
People wonder why we have so many obese poor, when it’s easily explained by the empty calories provided by high carbohydrate diets prevalent among them. Real food takes preparation and doesn’t last for months on a shelf. The healthiest diets from around the world are similar—simple foods where fats provide a majority of calories, a good portion of clean proteins and a mix of complex carbohydrates.
