Marathon DPC - GLP-1s For Weight Loss

GLP-1s for weight loss: A Physician -Guided Protocol for Sustainable Fat Loss

GLP-1s can drive rapid weight loss. But without a personalized strategy, this can lead to muscle loss and decreased strength

GLP-1s work. But how you use them matters

Medications like semaglutide (Ozempic) or tirzepatide (Mounjaro, Zepbound) are powerful tools for weight loss. But appetite suppression without appropriate protein intake and resistance training can lead to unintended consequences

Why we created a GLP-1 program

Too many people start GLP-1 medications without the guidance they truly need. They follow the prescription but receive little to no support.

As a result, they often lose muscle instead of fat, feel frustrated with their progress, and don’t achieve the results they hoped for.

Our role is to ensure that while body weight changes, we protect muscle, strength and long term health.

Unlike other clinics, we ONLY use FDA approved GLP-1s

Do GLP-1s cause muscle loss?

They can, but they don’t have too.

GLP-1s reduce appetite and slow gatric emptying which leads to a drop in calories and protein intake.

Data shows that without enough protein, resistance training & monitoring, a meaningful portion of weight lost can come from muscle rather than fat

Weight loss ≠ fat loss

The scale cannot tell you

How much fat vs muscle you are losing
If strength is being preserved
If metabolic health is improving
If bone density is becoming compromised
