Drinks lead
Eight of the top 10 are drinks. Protein has 4 calories per gram, and a lean shake adds little else. Powders and broths are left out, since their label is one scoop with water. For food, StarKist tuna (17g, 70 calories) and Oikos Triple Zero tubs (17g, 80) are the leanest.
Fiber
- Julian Bakery Egg White Bar: 17g fiber with 20g protein, 170 calories.
- Atkins Strong, Milk Chocolate: 30g protein and 7g fiber in 159 calories.
- Kashi GO Original: 12g protein and 12g fiber, measured dry.
Bars often hit fiber claims with added fibers and sugar alcohols. Read the panel.
The limits
This is label math, not a diet plan. It doesn't know your total calories or activity. It shows which snacks give the most protein for the calories you choose to spend.
How we rank
Every product here lists more than 8g protein, 180 calories or fewer per serving. Anything that misses either line is out, with no exceptions.
We rank by protein per 100 calories, using the protein, calories and price on the Amazon listing as last checked on Nov 5, 2026. Listings whose numbers can't all be true are held back until we check the label. Confirm the live listing and the package before you buy.

Questions about high protein snacks for weight loss under 180 calories
Do high protein snacks help with weight loss?
Not by themselves. Weight change follows total calories. A high protein snack is useful because it gives you more protein for the calories you were going to spend on a snack anyway.
What are good high protein snacks for weight loss under 180 calories?
Look for the most protein per 100 calories. Chobani 30g Protein Drink (30g, 120 calories), Muscle Milk Pro Series (40g, 160), StarKist tuna pouches (17g, 70) and Protein Pop (22g, 100) lead the catalog.
What are the benefits of high protein snacks?
The practical benefit is measurability. A snack with more than 8g protein and 180 calories or fewer per serving gives you two fixed numbers to budget, instead of a vague healthy-snack claim.
Are high fiber high protein snacks better?
They can be, if the fiber is real and the calories hold. Julian Bakery Egg White Bars list 17g fiber with 20g protein at 170 calories. Check total carbs and sugar alcohols on the panel, since bars often add fiber to hit a claim.
How many high protein snacks fit in 300 calories?
Two, comfortably. Chobani 30g Protein Drink plus a David Protein Bar is 270 calories and 58g protein. Chobani 20g Protein Vanilla plus Ratio Strawberry is 270 calories and 45g.
Does 180cal give weight-loss or medical advice?
No. This is calorie and protein math from product labels, not a diet plan. Confirm the live Amazon listing and the package label before you buy.
