You've heard the weight loss success stories, but what about the hidden cost? While the scale drops, something precious might be disappearing too – your muscle. With the rise of GLP-1 medications helping millions shed pounds rapidly, a critical question emerges: are we losing the right kind of weight?

The harsh reality is that for every pound you lose, up to 25% could be lean muscle mass. And here's the kicker – when you regain weight (which happens to most people), you don't get that muscle back. You end up at the same weight but with a completely different body composition, setting yourself up for a metabolic disaster. But there's hope, and the solution is simpler than you might think.

Join Holly and Jim as they welcome Dr. Stuart Phillips, one of the world's leading experts in muscle physiology and protein metabolism. As a distinguished university professor at McMaster University and holder of a Tier 1 Canada Research Chair in Skeletal Muscle Health, Dr. Phillips has spent decades uncovering the secrets that bodybuilders and physique competitors use to lose fat while preserving every precious gram of muscle.
