Why Protein Intake Is So Important on GLP-1: How to Protect Muscle While Losing Fat

December 24, 20253 min read

Disclaimer: This post is for educational purposes only and is not medical advice. We do not sell or prescribe GLP-1 medications. Our goal is to help individuals who are already on a GLP-1 learn how to eat right, train effectively, and protect muscle while losing fat. Always consult your doctor before starting or adjusting any medication.


Muscle Isn’t Built in the Gym — It’s Protected in the Kitchen.

If you’re currently using a GLP-1 medication, you’ve probably noticed how fast the scale moves.
The problem? Not all of that weight loss is fat — and without enough protein, your body can start burning muscle instead.

At Game Changing Performance in Mundelein, we coach every GLP-1 client through one of the most important rules of long-term success:

Eat enough protein to protect your muscle while losing weight.


How Much Protein Do You Really Need?

A good baseline for anyone on a GLP-1 is at least 0.6 grams of protein per pound of body weight.

That means:

  • If you weigh 200 lbs → aim for 120 grams of protein per day

  • If you weigh 150 lbs → aim for 90 grams per day

This amount supports recovery, maintains lean muscle, and helps your metabolism stay active while your calories are lower.


Why Protein Is So Crucial on GLP-1

GLP-1s suppress appetite — which means many people eat significantly less food without even realizing it.
The result? Not enough nutrients to support muscle, energy, or hormone balance.

Here’s what happens when you prioritize protein:
✅ You burn fat, not muscle
✅ You stay full longer (reducing cravings)
✅ You maintain strength and energy
✅ You recover faster from workouts

Protein isn’t just about building muscle — it’s about preserving the body you’ve worked hard to create.


Easy Protein Sources for GLP-1 Users

When appetite is low, food choices need to be strategic. At Game Changing Performance, we help clients simplify nutrition with easy-to-digest, high-protein foods that don’t cause nausea or discomfort:

  • Chicken breast or turkey

  • Eggs and egg whites

  • Fish and shrimp

  • Greek yogurt or cottage cheese

  • Protein shakes or powders (when whole foods feel tough)

  • Lean steak, pork tenderloin, or bison

It’s not about eating large portions — it’s about making every bite count.


Pairing Protein With Strength Training

Protein alone isn’t enough — your body also needs a reason to keep muscle. That’s where strength training comes in.

Our GLP-1 Coaching Program combines both:

  • Customized nutrition plans built around your protein needs

  • Resistance training programs designed for energy levels and recovery

  • Accountability coaching to help you stay consistent when motivation fades

Together, nutrition and strength training are what create lasting, healthy transformation — not just quick weight loss.

We’ve lived this process ourselves — and we know what it takes to do it right.


Final Thoughts

GLP-1s can change how your body responds to food — but you control what happens next.
By eating enough protein and staying consistent with strength training, you can build a body that’s strong, healthy, and sustainable long after the medication.
