In today's video, I'm reacting to Gina Echols' advice about GLP-1 medications, muscle loss, protein, and strength training. While I actually agree with several of her recommendations, one of her later claims appears to contradict the muscle-building principles she explained earlier.
We'll talk about what the current body of scientific evidence says about preserving muscle during weight loss, why protein matters, the role of resistance training, and why it's important to understand the difference between lean mass and skeletal muscle when discussing GLP-1 medications.
📚 Studies and resources referenced in this video are linked below so you can read the evidence for yourself.
