The Claim

In healthy young adults, consumption of dairy at breakfast increases postprandial glucagon-like peptide-1 (GLP-1) levels in a dose-dependent manner, leading to enhanced satiety and reduced glucose response independent of insulin.

How it works
1 study reviewed
In plain English

Eating dairy at breakfast raises levels of the hormone GLP-1 after eating, which results in greater feelings of fullness and lower blood sugar levels without changes in insulin.

See the scientific wording

In healthy young adults, consuming dairy at breakfast increases postprandial glucagon-like peptide-1 (GLP-1) in a dose-dependent manner, which may contribute to enhanced satiety and reduced glucose response independently of insulin.

Why this might work

When dairy is eaten for breakfast, proteins in the dairy break down into amino acids that travel to the gut and trigger special cells to release a hormone called GLP-1. This hormone tells the pancreas to stop releasing glucagon, which lowers blood sugar, and sends signals to the brain to reduce hunger. This happens without changing insulin levels.

  1. Study: Graded Replacement of Carbohydrate-Rich Breakfast Products with Dairy Products: Effects on Postprandial Aminoacidemia, Glycemic Control, Bone Metabolism, and Satiety.

    This study found that when young, healthy people eat dairy for breakfast, their bodies release more of a fullness hormone called GLP-1—and the more dairy they eat, the more hormone they release. This helps lower blood sugar without changing insulin, which explains why they felt fuller longer.
