INSIGHT

Insulin Resistance Causes Chronic Disease

Insulin resistance underlies nearly all chronic diseases, including cancer.
Frequent eating triggers insulin resistance by constantly elevating insulin levels, blocking cell fuel uptake.

ADVICE

Benefits of 18-Hour Intermittent Fast

Try intermittent fasting with an 18-hour fast and a 6-hour eating window.
This approach helps reduce belly fat, improves mood, and lowers inflammation.

INSIGHT

Extended Fasting Fuel Shift

Extended fasting depletes liver glycogen and initially causes significant water weight loss.
After 1-2 days, your body primarily burns ketones, boosting muscle growth and fat burning with elevated growth hormone levels.

Did you know that insulin resistance is behind most chronic diseases, including many types of cancer? Frequent eating leads to insulin resistance, which blocks cells from getting fuel. Diets involving 5 to 6 small meals daily destroy the metabolism the most!

An intermittent fasting plan involving 18 hours of fasting with a 6-hour eating window can provide tremendous health benefits, such as weight loss in the midsection, improved mood, and decreased inflammation.

A 24 to 48-hour fast can significantly magnify the benefits of fasting. Extended fasting enables you to deplete the stored glycogen in your liver. You may also notice significant initial water weight loss.

During a 1 to 2-day fast, most of your fuel will come from ketones. Your microbes will thrive, and growth hormone will increase, boosting muscle growth and burning fat.Ketones will feed the neurons in the brain, so you may notice improved cognitive function.Extended fasting allows you to get into a state of autophagy, where your body removes damaged cells and proteins and creates new ones. Autophagy also allows you to build new brain cells.

A 3-day fast can produce even more benefits! Extended fasting for 72 hours can clean up intracellular pathogens, including Epstein-Barr and herpes viruses.

A 3-day fast can stimulate your immune system, protecting you against cancer and autoimmune diseases. You can achieve results similar to stem cell therapy for free!

If you’re unsure of how to fast and want to make the process as comfortable and beneficial as possible, try these fasting tips for the most fasting benefits:

•Coffee and tea are okay during a water fast

•Make sure you have enough sea salt

•Consume electrolytes like potassium and magnesium

Refeeding can have a negative impact after a 3-day fast. It’s best to rebuild your caloric intake slowly. Bone broth is a great option to break your fast.
