Dr Chalmers Path to Pro - Fasting and Muscle Loss

August 15, 2025

Fasting can be a useful way to improve health and manage weight, but it’s not the same for everyone. Your body type, metabolism, and hormones all affect how you respond, and knowing whether you’re an ectomorph, mesomorph, or endomorph can help prevent problems like muscle loss and low energy.


It’s important to understand how your body uses fuel, why easing into fat-burning mode matters, and how the right nutrients can support the process. Factors like gender differences, gut health, and hormone balance also play a big role in making fasting safe and effective.
