PROTEIN COMPARISONS

Protein Files

Every shake, bar, and sippable ranked by protein density — because you eat small, not often.

When your stomach is the size of a shot glass, "20g per serving" doesn't tell you anything useful. What you need is grams of protein per 100 calories — the only metric that matters when your stomach has 200 calories of room and you've already used 80 on a banana.

Protein Files compares the shakes, bars, and sippables that GLP-1 users actually tolerate, ranked by the only number that counts. We weigh taste-tolerance, label cleanliness, and price-per-gram alongside the density math. Brand-payment-free, every single time.
