The Claim

The insulin-to-glucagon ratio directly determines the rate of lipolytic activity in human adipose tissue.

How it works
2 studies reviewed
In plain English

The balance between insulin and glucagon in the blood controls how much fat is broken down in human fat tissue.

See the scientific wording

The insulin-to-glucagon ratio is a primary determinant of lipolytic activity in human adipose tissue.

Why this might work

When insulin levels are high, it binds to fat cells and turns off the enzyme that breaks down fat, preventing fatty acids from being released. When glucagon levels rise, it does not turn on fat breakdown in human fat tissue. The amount of fat released depends on how strongly insulin can block this enzyme, not on glucagon's activity.

2 studies
  1. Study: The Anti-Lipolytic Effect of Insulin in Adipocytes Associates with the Magnitude of Dietary Induced Loss in Body Weight and Fat Mass: A Longitudinal Study

    When insulin is better at telling fat cells to stop breaking down fat, people lose more weight — even when eating the same diet. This suggests that the balance between insulin and glucagon (which does the opposite) controls how much fat your body burns.

  2. Study: Action of glucagon and glucagon-like peptide-1-(7-36) amide on lipolysis in human subcutaneous adipose tissue and skeletal muscle in vivo.

    The study found that giving glucagon — a hormone thought to help break down fat — didn’t make fat tissue break down any more in humans. This contradicts the idea that the balance between insulin and glucagon controls fat breakdown.
