The Claim

Ten days of total energy deprivation in healthy, normal-weight males is associated with a minor and gradual increase in cortisol levels and an increase in nocturnal urinary adrenaline excretion, indicating activation of stress-response pathways during prolonged fasting.

Source: Effects of total energy withdrawal (fasting) on thelevels of growth hormone, thyrotropin, cortisol, adrenaline, noradrenaline, T4, T3, and rT3 in healthy males.

In plain English

In healthy, normal-weight men, ten days of complete fasting leads to a small, steady rise in cortisol and increased adrenaline in nighttime urine, reflecting heightened activity in the body's stress-response systems.

Why this might work

When the body runs out of food for ten days, it detects low energy and turns on stress hormones to keep the brain and heart running. The brain signals the adrenal glands to release more cortisol and adrenaline, especially at night. These hormones break down fat for fuel and stop the body from using sugar unnecessarily, so vital organs get what they need to survive.

  1. Study: Effects of total energy withdrawal (fasting) on thelevels of growth hormone, thyrotropin, cortisol, adrenaline, noradrenaline, T4, T3, and rT3 in healthy males.

    When healthy men fast for 10 days, their bodies release a little more of the stress hormone cortisol and more adrenaline at night, which helps them survive without food by conserving energy and keeping vital organs running.
