How to fast
to fit your goals & lifestyle
The reality is that humans have always fasted. In prehistoric times, we often went days between eating because we simply couldn’t find food. Over millions of years, we evolved to not only handle the threat and stress of not eating - we thrived. Why? Because prolonged fasting – and only fasting – triggers our amazing, natural cell clean up and rejuvenation process. This helps us live longer and healthier.
Yes, we now live in a world in which food is available 24 hours a day, 7 days a week. But nature, science, and evolution tell us that we’re built to fast.
What is fasting?
Abstinence from all or some kinds of food and drink.
The switch from burning external glucose for energy to burning internal fatty acids and ketones as main source of fuel; more efficient use of energy.
The absence of triggers of nutrient sensing pathways; stimulation of stress resistance.
