Visceral adipose tissue (VAT)
What a GLP-1 receptor agonist actually does: which receptors it reaches, how it slows gastric emptying, and the satiety pathway it runs through.
What is Visceral adipose tissue (VAT)?
Fat packed deep in the abdomen around the liver, pancreas and intestines, as opposed to the subcutaneous fat under the skin.
It is the metabolically dangerous kind. DEXA substudies of STEP-1 and SURMOUNT-1 found GLP-1s strip it preferentially, which helps explain why cardiometabolic risk falls faster on these drugs than on calorie restriction reaching the same weight.
