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.
What is Autophagy?
Autophagy is the name for your body’s natural cell optimization process that usually starts on day 3 of a prolonged fast. Your cells optimize and recycle old and damaged parts resulting in a profound benefit: cell rejuvenation.
What is Ketogenesis?
Ketogenesis is the biochemical process through which organisms produce ketones by breaking down fatty acids and ketogenic amino acids. Ketosis is a metabolic state in which there’s a high concentration of ketones in the blood, which happens when fat is used most of the fuel for the body rather than glucose.
Prolonged fasts unlock the deepest level of fasting. It triggers your body’s natural way of cleaning house. Your cells clean and recycle old and damaged parts, resulting in a profound benefit: cell rejuvenation. Your cells renew themselves and act like younger cells.
The practice of fasting involves calorie restriction.
Do not start a fast if:
• During this period of COVID-19, if you are over 65 years of age, or are in a high-risk category.
• If you have a diagnosis of or are on a prescription for diabetes (type 1 or type 2), cancer, or congestive heart failure, or you have a history of fainting, fast only with the approval and supervision of a healthcare practitioner.
• If you have a fever, cough, diarrhea, signs of an active infection, or are at risk for a repetitive infection.
• You are underweight, pregnant, or breastfeeding.
• If you have a known, diagnosed, or suspected eating disorder.
• You are under 18 years of age over the age of 70.
• You have dietary restrictions
• You are underweight or do not want to lose weight - during the fasting period, an individual will naturally lose 2-5% of his/her body weight
