Key Ideas

Fasting improves insulin sensitivity

When more food is available, the cells in the body become less sensitive to insulin. When the food supply is scarce, during fasting, the human body tries to conserve as much energy as possible and cell membranes more sensitive to insulin, metabolising it better.

Fasting reverses chronic conditions

... like obesity & type 2 diabetes, both of which are risk factors for cancer. Studies have shown that fasting two to three times per week lowers weight and improves insulin tolerance. 

Fasting promotes autophagy

Autophagy is a cellular process in which parts of cells break down for later reuse. 

Autophagy is critical for maintaining proper cell function, and it also helps defend cells in the body. Autophagy plays an important role in preventing and treating cancer.

Fasting improves quality of life during chemotherapy

Early studies are showing fasting may help reduce chemotherapy-related headaches and nausea, because it promotes cellular regeneration.

The function of ketones

Ketones aren’t just a form of energy, they’re powerful signaling molecules. They regulate the expression of genes and dampen inflammatory processes.
Your body is always producing a very low level of ketones, irrespective of your diet. You start producing more of them when following a diet that’s high in fat and low in carbs.

Getting in ketosis
  • The stricter you restrict carbs (or total calories), the quicker you will be in ketosis.
  • Restricting your carb intake to 20g per day is a good heuristic (loose rule) for entering ketosis. It will generally get you into ketosis within a few days.
  • Fasting gets you into ketosis very quickly.

Keto is a cultural identity

Keto is more than just a diet. It is a cultural identity.

The Keto diet changes how adherents think about medicine and nutrition. With the fake news that dominates the news cycle, it's not surprising that keto went viral. It's anti-establishment.

Understanding ketosis

The body can only store glucose to last a few days. If we don't eat carbs, the body finds other ways to fuel the body, like ketogenesis. In ketogenesis:

  • The liver starts to break down fat from food and our body reserves. The useful energy source is called ketone bodies and can replace glucose as fuel when there's a glucose shortage.
  • Once ketogenesis starts, the ketone levels rise.
  • The body burns fat instead of the usual glucose.

Popular types of fasting
  • Intermittent fasts: eating no food or massively cutting back on calorie intake only intermittently;
  • Time-restricted feeding: involves consuming calories only for a 4- to 6-hour window each day.
  • Periodic fasts, the most extreme, typically last several days or longer. 
  • Fasting-mimicking diet, a plant-based diet that involves eating very few calories for several days each month. 
Religious fasting

Many religious groups incorporate periods of fasting into their rituals, though the focus there tends to be more spiritual than health-oriented: Muslims fast from dawn until dusk during the month of Ramadan, Christians, Jews, Buddhists, and Hindus who traditionally fast on designated days of the week or calendar year.
