The Claim

Excess thyroid hormone increases metabolic rate, leading to weight loss, increased bowel frequency, and elevated body temperature.

How it works
2 studies reviewed
In plain English

When thyroid hormone levels are too high, the body burns energy faster, resulting in lower body weight, more frequent bowel movements, and a higher body temperature.

See the scientific wording

Excess thyroid hormone increases metabolic rate, resulting in weight loss, increased bowel frequency, and elevated body temperature.

Why this might work

Excess thyroid hormone enters cells and turns on genes that make more energy-producing machines called mitochondria, while also breaking down proteins to fuel them. This forces cells to burn more fuel, releasing heat and using up stored energy, which raises body temperature, burns fat and muscle, and speeds up digestion.

What the research says

2 studies
  1. Study: In vivo regulation of human skeletal muscle gene expression by thyroid hormone.

    When people are given extra thyroid hormone, their body’s cells start working harder and burning more energy, which explains why they lose weight, have more bowel movements, and feel hotter.

  2. Study: Pregnancy negates thyroid hormone-induced pyrexia.

    When pregnant mice were given extra thyroid hormone, their body temperature went up at first, just like the claim says. Even though their bodies later adjusted to protect the baby, the hormone still made their metabolism work harder, which supports the idea that too much thyroid hormone makes your body burn more energy and get warmer.
