High-protein snacks under 180 calories

Ready-to-drink protein shakes carry the most protein per serving in this catalog: 70 of the 648 qualifying products list 30g protein or more while staying under 180 calories. Sort the grid by Highest protein to see them, or by Protein density to rank by grams of protein per 100 calories instead.

180cal draws the line at more than 8g of protein per serving, with 180 calories or fewer. Together the two limits mean every product on this page carries more than 4.4g of protein per 100 calories. Protein density, not grams alone, is what separates a lean snack from a large one.

Yes — 154 of the 648 products on this page list fewer than 100 calories per serving while still carrying more than 8g of protein. Set the Calories filter to Under 100 to see them, or open the under-100-calorie collection for the full list with protein density figures.

That depends on the bar and on the person. 180cal does not rate how filling a snack is — it publishes the numbers so you can judge for yourself, and each card shows protein, calories, and grams of protein per 100 calories. 129 bars currently clear the 8g protein and 180 calorie rule.

The figures come from the Amazon listing and the product label, and each product stores the date it was last checked. Nutrition figures were last verified on July 9, 2026; Amazon price and availability are refreshed more often and are confirmed on Amazon at checkout. Brands reformulate and sellers change pack sizes, so confirm the nutrition panel on the Amazon listing before buying.

180cal doesn't sell, stock or ship anything: every product link opens the Amazon listing, where price, delivery, returns and checkout happen. 180cal earns Amazon Associates commissions on qualifying purchases at no extra cost to you, and sells brand placements through its partners page. Every product, sponsored or not, still has to list more than 8g protein, 180 calories or fewer per serving, and 648 currently do.
