Protein Requirements on GLP-1s: The Numbers You Actually Need

Updated January 2026

----------|---------|---------| | 180 lbs (82 kg) | 98g | 131g | | 200 lbs (91 kg) | 109g | 146g | | 220 lbs (100 kg) | 120g | 160g | | 250 lbs (114 kg) | 137g | 182g | | 280 lbs (127 kg) | 152g | 203g |

If you're 220 lbs, you need 120-160g protein daily. That's a lot when your appetite is suppressed.

The Problem: Appetite Suppression

GLP-1s work by reducing appetite. Great for overall calories. Terrible for hitting protein targets.

What happens: - Total food intake drops 20-40% - If you don't prioritize protein, it drops proportionally - You end up eating 60-80g protein (not enough) - Muscle loss accelerates

The solution: Protein must be prioritized over everything else. When appetite is limited, protein is not optional — it's first priority.

Protein Strategy

Eat Protein First

At every meal, eat the protein before anything else. If you get full and can't finish, at least the protein is in.

Higher Protein Per Meal

With reduced appetite, you may eat fewer meals. Each meal needs more protein.

Target: 30-50g protein per meal Example: 3 meals × 40g = 120g (minimum achieved)

Protein at Every Eating Occasion

No "snacks" without protein. If you eat, protein is involved.

Protein Supplements

Reduced appetite makes whole food harder. Supplements help: - Whey protein: 25-30g per scoop, easy to consume - Protein bars: 20-25g, convenient - Fairlife/Premier Protein shakes: 30g, grab-and-go

Best Protein Sources

Per ounce of food: - Chicken breast: 8g - Greek yogurt (cup): 17g - Whey protein (scoop): 25-30g - Eggs (each): 6g - Beef: 7g - Fish: 6-7g - Cottage cheese (cup): 25g

Sample Day: 160g Protein

Breakfast: - Greek yogurt (17g) - 2 eggs (12g) - Protein shake (25g) Total: 54g

Lunch: - 6 oz chicken breast (48g) - Vegetables, small portion starch Total: 48g

Dinner: - 6 oz beef/fish (42g) - Vegetables Total: 42g

Snack: - Protein bar (20g) Total: 20g

Day Total: 164g

When Appetite Is Really Low

Some days on GLP-1s, eating anything feels hard. Strategies:

Liquid calories

Protein shakes go down easier than solid food. 2-3 shakes can provide 60-90g protein.

Cold foods

Many find cold foods more tolerable (yogurt, protein shakes, cold cuts).

Smaller portions, more frequently

If you can't eat 40g at once, eat 20g twice as often.

Timing around medication

Some men have better appetite on certain days of injection cycle. Time bigger protein meals accordingly.

Tracking Protein

Until it's habit, track your protein: - MyFitnessPal - Cronometer - Simple notepad

Most men think they eat more protein than they do. Track for a week and see reality.

Signs You're Undereating Protein

If these appear, audit your protein intake immediately.

The Trade-Off

"I can't eat that much protein."

Then accept more muscle loss. That's the trade-off.

Protein is the controllable factor. Medication dose isn't. Training stimulus has limits. Protein is where you have leverage.

Men who prioritize protein maintain muscle. Men who eat whatever fits their reduced appetite lose more muscle. Choose.

The Bottom Line

GLP-1s reduce appetite. Protein must be prioritized or you'll undereat it.

The protocol: 1. Calculate your target (1.2-1.6g/kg body weight) 2. Track intake until hitting target is automatic 3. Eat protein first at every meal 4. Supplement when whole food is too hard 5. Never let a day go by under target

Your muscle retention depends on it.
