Protein goals on a GLP-1: the simple formula

If you're on a GLP-1 and you take one thing from this column, let it be this: protein is not optional anymore. It's the difference between weight loss that feels sustainable and weight loss that leaves you tired, flat, and losing the wrong tissue.
The simple formula
A useful starting point that providers commonly recommend: aim for roughly 0.8 grams of protein per pound of your goal body weight, per day. If your goal is 150 lbs, that's about 120 grams. It sounds like a lot. On a GLP-1, where you're eating less total food anyway, it's a real target — but it's reachable when you front-load.
A 3-day template
| Day | Breakfast | Lunch | Dinner | Snack | ~Total |
|---|---|---|---|---|---|
| Mon | Greek yogurt + berries (25g) | Chicken bowl (40g) | Salmon + veg (35g) | Cottage cheese (15g) | ~115g |
| Tue | Scramble + turkey (30g) | Shrimp salad (35g) | Lean steak (40g) | Protein shake (20g) | ~125g |
| Wed | Protein oats (28g) | Tuna wrap (32g) | Ground turkey chili (38g) | String cheese x2 (14g) | ~112g |
Why this matters so much on a GLP-1
GLP-1 medications reduce the total volume of food you want to eat. That's the point. The risk is that you lose muscle along with fat, especially if your protein drifts low. Muscle is what keeps your metabolism active, your strength up, and your next phase easier. Under-eating protein is the fastest way to stall a plan that was working.
“Eat the protein before you're full. That's the whole game.”
