Intermittent Fasting

Are there dangers with prolonged fasting?

Prolonged fasting is very beneficial to support a healthy body. However, there is one aspect of prolonged fasting that can be dangerous, and that’s what we’re going to cover today.

Prolonged fasting is when you fast for three or more days. The biggest danger of prolonged fasting is called refeeding syndrome. This can happen if a person consumes too much of the wrong foods too fast after coming off of a prolonged fast.

Rare complications of refeeding syndrome can include coma, seizures, convulsions, and death.

Refeeding syndrome typically involves malnutrition.

Certain conditions cause a higher risk of refeeding syndrome, such as:

• Eating disorders

• Alcoholism

• Type 1 diabetes

• Starvation

However, the risk of refeeding syndrome is low if you aren’t malnourished going into a prolonged fast. As a bare minimum, when you start any type of fasting, you need to take electrolytes and B vitamins.

How to come off of a prolonged fast:

1. Consume foods that align with Healthy Keto®

2. Take electrolytes and B vitamins while fasting (you may also want to take cod liver oil, vitamin D, vitamin K2, and trace minerals)

3. Gradually consume very small amounts of food
