For GLP-1 Users

Lose the fat.
Keep the
muscle.

Up to 40% of the weight you lose on Ozempic, Wegovy, or Mounjaro can come from lean body mass. Xwerks Grow delivers 25g of grass-fed whey isolate per scoop — the cleanest way to protect the muscle your metabolism depends on.

The Hidden Cost of GLP-1s
Your medication is working.
Your muscles are paying for it.

GLP-1 drugs suppress appetite and drive serious weight loss. But that same appetite suppression makes it dangerously hard to eat enough protein — right when your body needs it most.

01

Up to 40% lean mass loss

Research shows GLP-1 users lose 20–40% of total weight from lean body mass — far higher than traditional dieting. That's muscle, bone density, and metabolic tissue disappearing alongside the fat.

Frontiers in Nutrition, 2025 · Circulation, 2025
02

Only 5% hit protein targets

A cross-sectional study found only 5% of GLP-1 users consumed the recommended 2.0 g/kg of protein daily. Most fell well below even the minimum 1.2 g/kg threshold for muscle preservation.

Frontiers in Nutrition, 2025
03

Less appetite, more need

GLP-1 medications suppress appetite and shift food preferences away from protein — precisely when your body needs more protein, not less, to maintain muscle during rapid weight loss.

How much protein
do you need?

Researchers recommend 1.2–2.0 g/kg of body weight daily for people on GLP-1 therapy. Use this calculator to find your target — and how Grow helps you get there.

1

Preserve Lean Mass

Adequate protein maintains muscle during caloric deficit, keeping your metabolism elevated as you lose weight.

2

Maximize Fat Loss

Higher protein shifts body composition toward greater fat-to-lean loss ratio. Lose what you want, keep what you need.

3

Fast Absorption

Whey isolate delivers amino acids rapidly — critical when GLP-1s slow gastric emptying and make heavy meals uncomfortable.

What the Research Says
The science is clear.
Protein protects muscle
during GLP-1 therapy.
Frontiers in Nutrition · 2025
Only 43% met the minimum 1.2 g/kg protein threshold
A study of GLP-1 receptor agonist users found the vast majority fell short of protein targets needed to preserve lean mass during pharmacological weight loss.
Endocrine Society · ENDO 2025
Higher protein may protect against muscle loss on semaglutide
Researchers at Massachusetts General Hospital found women and older adults on semaglutide face elevated muscle loss risk — but higher protein intake showed protective effects.
Circulation (AHA) · 2025
1.2 g/kg preserved metabolic gains lost at 0.8 g/kg
Standard protein intake during weight loss impaired insulin signaling improvements that higher protein intakes preserved — a key reason to aim above the RDA on GLP-1s.
ScienceDirect · 2025
Even protein distribution increased MPS by 25%
A crossover feeding study showed distributing ~25–30g protein per meal boosted muscle protein synthesis versus eating protein mostly at dinner — crucial for GLP-1 users managing reduced appetite.

How to Use Grow on GLP-1s
Spread your protein.
Maximize the effect.

Research shows distributing protein evenly across meals optimizes muscle protein synthesis by up to 25%. Here's how to structure Grow around reduced appetite.

AM
Morning
Breakfast Shake
1 scoop with ice and water when solid food doesn't appeal. An easy 25g to start the day. Add a banana if appetite allows.
MID
Post-Workout
Training Recovery
1 scoop after resistance training. Pairs the stimulus with the building blocks muscle needs. Mix into oatmeal or yogurt if preferred.
PM
Evening
Protein Top-Off
If dinner was light (common on GLP-1s), a final scoop closes the gap. Slow-sip as a shake or stir into cottage cheese.

Protein FAQ
No. Whey protein is a food, not a pharmaceutical — it doesn't interact with semaglutide, tirzepatide, or liraglutide. Major medical organizations recommend increasing protein intake while on GLP-1 therapy. Always consult your prescribing physician with medication-specific questions.
This is exactly why a protein isolate matters. Grow packs 25g of protein into just 110 calories with a light, smooth texture. Many GLP-1 users find liquid nutrition far easier to consume than solid food when appetite is suppressed. Start with one scoop in the morning and build from there.
Whey isolate is the purest form of whey — higher protein per calorie, virtually no lactose, faster absorption. GLP-1 medications slow gastric emptying, so a fast-absorbing protein is less likely to cause GI discomfort. Grow is 100% isolate, never blended with cheaper concentrates.
Current research recommends 1.2–2.0 grams per kilogram of body weight daily during pharmacological weight loss. For a 180 lb person, that's roughly 98–163g of protein daily. Use our calculator above to dial in your personal target.
Both matter. The strongest evidence combines adequate protein with structured resistance training at least 2 days per week. Think of protein as the raw material and training as the signal telling your body to use it for muscle, not just energy.
Grow is 100% grass-fed whey protein isolate from New Zealand — not a blend. It's cold microfiltered, naturally sweetened with stevia, and contains zero artificial colors, no soy, and no fillers. 25g of protein in only 110 calories. For GLP-1 users watching every calorie, that ratio is hard to beat.
