Is a low-fat vegan diet costing you muscle mass?

I used to be a total cardio junkie and vegan, thinking I was doing the healthiest thing possible until a humiliating body composition test revealed my body fat had skyrocketed to 25%. Today, I am walking you through the physiological breakdown that occurs with chronic endurance training and inadequate protein, explaining why these habits can lead to a "muscle loss cocktail" and metabolic disaster. My goal is to share how shifting to a "muscle first" philosophy, incorporating resistance training, HIIT, and optimal amino acid balance, is the true key to aging powerfully.

What you’ll learn:

(02:00) Why chronic endurance training combined with a low-fat vegan diet led to muscle loss and increased body fat.

(05:02) How prolonged endurance exercise can elevate cortisol and create a catabolic environment when recovery and protein intake are insufficient.

(07:41) What research shows about muscle protein synthesis on vegan versus omnivore diets when protein intake is matched.

(09:16) Why athletes require more protein than the standard RDA to preserve lean mass and support recovery.

(10:52) How skeletal muscle mass directly influences resting metabolic rate and long-term fat burning.

(12:13) Why muscle is the body’s primary site for glucose disposal and essential for insulin sensitivity.

(15:19) How high-intensity interval training can stimulate mitochondrial growth and improve metabolic health in less time than traditional endurance training.

(19:42) Why essential amino acids can act as “muscle insurance,” especially for women over 40 facing anabolic resistance.
