The Claim

Dietary linoleic acid is metabolized into endocannabinoid ligands that activate CB1 receptors in the brain, resulting in increased appetite.

How it works
2 studies reviewed
In plain English

Consuming linoleic acid, a type of fat found in certain oils, leads to the production of molecules that bind to CB1 receptors in the brain, which can lead to an increase in hunger.

See the scientific wording

Dietary linoleic acid is metabolized into endocannabinoid ligands that activate CB1 receptors in the brain, increasing appetite.

Why this might work

When you eat a lot of linoleic acid — like from vegetable oils — your body turns it into another fat called arachidonic acid. That fat is then used to make chemicals that bind to special receptors in the brain’s hunger center. When those receptors get activated, they make you feel hungrier and eat more.

What the research says

2 studies
  1. Study: Sex-Specific Changes to Brain Fatty Acids, Plasmalogen, and Plasma Endocannabinoids in Offspring Exposed to Maternal and Postnatal High-Linoleic-Acid Diets

    This study found that eating lots of linoleic acid (like in vegetable oils) leads to higher levels of brain chemicals that make you feel hungrier. These chemicals activate the same receptors in the brain that are involved in appetite.

  2. Study: Enhanced 2-arachidonoyl glycerol-dependent CB1 activation contributes to feeding dysregulation in KK-Ay mice.

    This study found that in obese mice, a chemical made from fats in the diet activates a brain signal that makes them eat more. Since linoleic acid is one of those fats, it supports the idea that eating more linoleic acid could make you hungrier.
