In this video, I want to talk to you about how fasting affects hormones.

I’m going to compare the effects of short (2-7 days) and long (8-20 days) fasts. This data is not based on intermittent fasting.

Adrenaline - This is a counter-regulatory hormone. During short fasts, adrenaline can increase. During long fasts, adrenaline lowers. When adrenaline levels are high, you may experience poor sleep. It can help to take calcium citrate or calcium lactate.

Cortisol - Cortisol is a stress hormone and a counter-regulatory hormone that will help prevent blood sugar levels from dropping too much. During short fasting, cortisol can raise, and during long fasts, cortisol tends to normalize.

Leptin - This is a hormone that helps you feel satisfied. When leptin is up, you feel satisfied and not hungry. However, way too much leptin causes leptin resistance—this is common in obese people. In turn, leptin stops working, so you never feel satisfied after eating. Both short and long fasts will lower leptin, which helps fix leptin resistance and restore your satisfaction after eating.

Insulin - One of the biggest benefits of fasting is lowering insulin levels. High insulin causes insulin resistance, which causes even higher levels of insulin that can develop into diabetes. Both short and long fasts help reduce insulin.

Serotonin - This hormone increases with both short and long fasts. Serotonin has a lot of cognitive benefits. It will help you sleep better at night and feel like you’re in a better state of well-being.

Growth hormone (GH) - This is the anti-aging hormone. It protects muscle, collagen, joints, and skin. Most people over 50 are deficient in GH. Both long and short-term fasting will increase growth hormone.

Glucagon - This is the opposing hormone to insulin. Levels of glucagon are raised with both short-term and long-term fasting. Glucagon helps you burn fat and prevent weight gain.

T3 - This thyroid hormone will actually lower with all forms of fasting. However, this will not harm your metabolism because it causes an increase in reverse T3.

Estrogen - Fasting will lower estrogen levels. This usually isn’t a big problem unless you have low estrogen. If you have low estrogen levels, you can take natural vitamin E to help balance your estrogen.
