How much protein should I eat on a GLP-1 like Ozempic or Zepbound?

Aim for 1.5–2.0 g of protein per kg of body weight per day. For a 75 kg person that is roughly 113–150 g. This is higher than the general 0.8 g/kg minimum because rapid weight loss increases the risk of losing lean muscle mass alongside fat.

Why is protein so important on GLP-1 medications?

Weight loss on GLP-1 medications is often fast, and without adequate protein plus resistance training a meaningful share of the weight lost can come from lean tissue rather than fat. Preserving muscle helps maintain strength, function, and easier long-term weight maintenance.

What should I do if I feel too full to eat enough protein?

Eat the protein portion of your meal first, choose protein-dense foods instead of high-volume ones, spread intake across 4–5 small occasions rather than 3 big meals, and use liquid protein such as shakes or yogurt drinks when solid food feels impossible.

Are protein shakes a good idea on a GLP-1?

Yes. Shakes are one of the most practical tools because liquid protein sidesteps early fullness and nausea. A standard scoop of whey or a plant blend delivers 20–25 g in a form that is easy to tolerate. Whole foods still come first when appetite allows.

Do I need to keep tracking protein if I'm barely hungry?

Especially then. GLP-1 medications suppress the hunger cues most people rely on, so it is very easy to end a day at 50–70 g of protein while feeling like you ate normally. Logging meals makes the shortfall visible while there is still time to fix it.

Which protein foods are best tolerated on a GLP-1?

Soft, mild, protein-dense foods tend to work best: Greek yogurt, cottage cheese, fish, shredded chicken, eggs, tofu, lentils, and protein shakes. Many users develop aversions to red meat and greasy foods, so switching sources rather than cutting protein is the fix.
