Buyer guide · for people eating less than they used to
When Appetite Is Low
When appetite drops — as it commonly does on GLP-1 medications — total food intake falls, but a protein target does not. This lane is about the honest problem that creates: getting enough protein, plus the fiber and electrolytes meals used to provide, into a smaller volume. It is general nutrition guidance, not medical advice; a range is a starting point, and your own targets belong with your clinician.
What matters most here
- A daily protein range from the Protein Target Calculator, confirmed with your clinician
- Protein-dense, small-volume products: powders, bars, and meal shakes
- Electrolytes and fiber, which are easy to under-eat once meals shrink
Honest note · Don’t chase the biggest tub or the record protein number — on a small appetite, the product you’ll actually finish beats the one that impresses on paper.
- Best Protein PowdersWhey isolate, concentrate, casein, and plant blends — ranked on protein-per-dollar, grams per scoop, and third-party testing.
- Best Meal ShakesComplete meal shakes in small volume — protein, fiber, and micronutrient coverage checked against the label.
- Best ElectrolytesSodium-forward mixes and tablets — read on the electrolyte panel and price per serving, not the marketing color.
