If You Have This Kind of Belly Fat, It’s Not From Food

About this video

Kane interviews a doctor about why belly fat can persist despite healthy eating and exercise. The featured doctor claims the problem is often hormonal rather than purely caloric, arguing that insulin resistance and chronic cortisol drive visceral fat, that visceral fat carries more cortisol receptors, and that more than a pound of it raises mortality risk, with fatty liver worse still. She discusses testing with DEXA scans, which she says cost her about $100, or home visceral-fat scales, checked at least yearly. She calls sleep the cornerstone, suggesting a cool bedroom around 68 to 69 degrees and morning light, and lists labs including insulin, A1C, DHEA-S, and hs-CRP. She also describes, as her claim, a patient losing about two pounds of visceral fat in roughly three months using the peptide tesamorelin, and names building muscle as her top action step.
