️ The number that doesn't move

The general protein recommendation — 0.8 grams per kilogram — was designed for healthy sedentary adults and may be insufficient during weight loss, aging, or illness. It's a floor, not a target.

Canned fish is the shortcut

Half a can of tuna or salmon on a few crackers delivers 15 to 20 grams of complete protein in under two minutes. No cooking, no cleanup, easy to eat in small amounts. On days when appetite shuts off early, canned fish is one of the most efficient protein options available.

The easiest protein in the world

Soft-scrambled 🥚 eggs are quick to make, easy to tolerate, and deliver complete protein with all essential amino acids. Two to three 🥚 eggs with a little 🥣 cottage cheese gets close to 20 grams in a portion most people can manage when appetite is very low.

Leucine is the signal

Research suggests that around 2 to 3 grams of leucine per meal may help stimulate muscle protein synthesis signaling in the presence of adequate total protein. Three 🥚 eggs contribute a portion of that threshold, and adding dairy or fish can help close the gap. 🥚 Eggs, dairy, and fish are among the richer leucine sources per gram of food.

A protein shake is a real tool on the days food feels impossible. Whey in cold water is not a meal replacement — it's a backup. Keep some on hand.

These are the letters that matter

Lower-fat protein sources may be easier to tolerate during slowed digestion. Lower-fat options like 🐟 white fish, 🥣 cottage cheese, and silken tofu may be easier to manage when the stomach is already moving slowly.

👖 How do I get enough protein on GLP-1?

Note: This article is for informational purposes only and does not constitute medical advice.

Early protein-sparing modified fast research showed that carefully designed very-low-calorie, high-protein diets could produce weight loss while helping preserve lean body mass. Fifty years later, a similar protein-first principle is often applied in weight loss contexts, including on GLP-1.

The medication changed. The math didn't. Meals on GLP-1 often carry a higher emphasis on protein — because there are fewer of them, and the body's need doesn't negotiate. A commonly used target is around 1.2 grams per kilogram per day during weight loss.
