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.

Ketosis
Is a metabolic state. Think of being in or out of ketosis like the settings in a hybrid car; you can rely on gas or electricity to different degrees.

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.

Intermittent Fasting (IF)
The dietary practice of restricting your food consumption to a specific window of time. It is used as a supplement to your diet.
In this fasting state, our bodies can break down extra fat...
Approaches to intermittent fasting
- Skipped meals - when you skip over a meal to induce extra time of fasting.
- Eating windows - this condenses your entire macronutrient intake between a 4 and 7-hour window. The rest of the time you are in a fasting state.
- 24-48 hour cleanse - where you go into extended fasting periods and do not eat for 1-2 days.
Autophagy definition and benefits
The process by which the cell devours itself.
- Non-essential parts like damaged proteins are recycled and invading microorganisms and toxic compounds are removed.
- Autophagy plays an important role in stopping the aging process, reversing disease, and preventing cancer, but it doesn’t happen all the time.
- Autophagic processes can be initiated by fasting, protein restriction and carbohydrate restriction.

Intermittent fasting
Fasting means abstinence of some or all food for a period of time.

A metabolic shift
It can take 10 to 12 hours to use up calories in the liver before your body changes over to use the stored fat.
After meals, glucose is used for energy, while fat is stored in fat tissue. During fasts, once glucose is depleted, stored fat is broken down and used for energy.
The easiest way to lose weight
To lose weight, strive for sixteen calorie-free hours. Stop eating by 8 pm, and eat again at noon the next day. Results can take up to four weeks to notice.
Intermittent dieters should eat healthy foods, including whole grains and healthy fats and protein. They should limit saturated fats and avoid sugar and refined carbohydrates. Be sure to stay well-hydrated.
