The Problem No One Talks About

GLP-1 medications work. But they’re taking your muscle with them.

Clinical research shows why: pharmacotherapy alone strips lean mass, slows metabolic rate, and sets up the rebound. Resistance training is the clinical counterpart that nobody is delivering.

40%

Muscle Loss

Up to 40% of weight lost on GLP-1 medications alone is lean muscle mass not just fat.

2/3

Weight Regain

Two-thirds of weight lost comes back within a year and it comes back as fat, not muscle.

The Vitelize Fix

Our hybrid model pairs GLP-1 therapy with supervised resistance training to preserve muscle and prevent fat regain.

Frequently Asked Questions

What is GLP-1 therapy and how does it work?

GLP-1 receptor agonists (like semaglutide and tirzepatide) are FDA-approved medications that work by mimicking a natural hormone that regulates appetite and blood sugar. They help you feel fuller longer, reduce food cravings, and improve your body’s response to insulin. When combined with our supervised resistance training, you get the weight loss benefits while preserving the lean muscle mass that GLP-1 alone can strip away.

Why is muscle preservation important during weight loss?

Research shows up to 40% of weight lost on GLP-1 medications alone is lean muscle mass. Muscle is metabolically active it burns calories at rest. When you lose muscle, your metabolism slows, making weight regain almost inevitable. That’s why two-thirds of GLP-1 weight loss comes back within a year. Supervised resistance training is the clinical solution to this problem.

How does the free consultation work?
