The Claim

In obese males, a 72-hour fasting period increases glycerol levels and reduces cortisol and glucagon concentrations when growth hormone signaling is pharmacologically blocked, indicating that growth hormone modulates the hormonal stress response during prolonged fasting.

How it works
1 study reviewed
In plain English

In obese men, going without food for 72 hours raises glycerol levels and lowers cortisol and glucagon levels when growth hormone is blocked, showing that growth hormone influences the body's hormonal response to extended fasting.

See the scientific wording

In obese males, 72-hour fasting increases glycerol levels and reduces counterregulatory hormones like cortisol and glucagon when growth hormone is blocked, suggesting GH modulates the hormonal stress response during prolonged fasting.

Why this might work

During fasting, growth hormone tells the liver to make more sugar and blocks the breakdown of fat from fat cells, which keeps glycerol low. It also signals the body to release stress hormones like cortisol and glucagon. When growth hormone is blocked, the liver stops making as much sugar, glycerol builds up because it is not being used, and stress hormones drop because the signal to release them is gone.

  1. Study: Substrate Metabolism and Insulin Sensitivity During Fasting in Obese Human Subjects: Impact of GH Blockade

    When obese men fast for three days and their growth hormone is blocked, their bodies release less of the stress hormones cortisol and glucagon, but more glycerol — showing that growth hormone normally helps trigger the body’s stress response during fasting.
