After a long hiatus, we're back!

Dr. Mark and Dr. Alan dive into body composition—aka why the number on the scale is not the whole story, and sometimes not even the right story. Come unpack the difference between weight loss and improving the ratio of lean muscle to body fat, explaining how muscle acts like a metabolic engine while excess visceral fat can drive inflammation, insulin resistance, and long-term health risks. (Basically, your bathroom scale may be dramatic, but your muscle-to-fat ratio is the real plot twist.)

The conversation also explores why maintaining muscle mass is one of the biggest keys to aging well, improving health span, and reducing mortality risk.

With a mix of research, real-world examples, and a little classic Peptide PhDs banter, this episode makes a strong case for building muscle, managing fat, and treating your body composition like the biological upgrade it is.

From air squats to incretin signaling, this one is packed with practical takeaways: lift something, eat enough protein, protect your muscle, and maybe stop letting your couch win the tug-of-war.
