Ever wonder why meal replacement shakes have such a bad reputation, even though some of the most successful weight loss stories involve exactly that?
There’s a lingering idea that meal replacements are outdated or that GLP-1 medications have completely replaced them, but that’s not the full picture. In this episode, we sit down with Jennifer Barlow, a board-certified family nurse practitioner and founder of True North Medical in Rhode Island, a practice focused on evidence-based obesity medicine and midlife health.
With more than 25 years of healthcare experience, Jennifer brings a unique perspective to the conversation, combining clinical expertise with her personal experience of losing more than 100 pounds and keeping it off.
We dive into what medical-grade meal replacements are actually made of, why very low-calorie diets can work when properly supervised, how ketosis affects hunger, and how meal replacements can complement medications like GLP-1s. We also discuss exercise, medical supervision, who may not be a good candidate, and how patients can transition off a program.
