Introduction:
With weight loss medications like Ozempic, Wegovy, and Mounjaro going viral, many are wondering:
“Should I get on meds, or stick to fasting?”
This blog breaks down the science, safety, and sustainability of GLP-1 drugs vs. intermittent fasting, so you can choose the method that fits your life, body, and long-term goals.
What Are GLP-1 Weight Loss Medications?
GLP-1 (Glucagon-Like Peptide-1) receptor agonists were designed for Type 2 diabetes — but they also suppress appetite and delay stomach emptying.
