Quick answer: The best foods with low calories high protein are egg whites, shrimp, cod, skinless chicken breast, and nonfat Greek yogurt. Each delivers 18–24g of protein for under 130 calories, so you can build a full day of meals around them without a spreadsheet.
What are foods with low calories high protein? They’re foods that pack a large amount of protein into a small calorie footprint — measured as grams of protein per 100 calories, also called protein density. A skinless chicken breast (31g protein / 165 calories) qualifies; a scoop of peanut butter (7g protein / 190 calories) doesn’t, even though both get labeled “high protein.”
Most lists of foods with low calories high protein just hand you a ranked table and leave you to figure out the rest. That’s useful for research, less useful at 7am when you’re deciding what to actually eat. This guide flips it: instead of category (meat, fish, dairy), it’s organized by when you’re eating — breakfast, lunch, snacks, and dinner — so you can grab a page and go.
Why Protein Density Matters More Than “High Protein”
According to a 2015 review published on PubMed Central, protein’s satiating effect depends on the amount eaten relative to total calories — not protein content alone. That’s the exact mechanism that separates foods with low calories high protein from foods that are simply high in protein. Two “high protein” foods can behave completely differently in a calorie-controlled day. In practice, most people find the 10g-of-protein-per-100-calories threshold is the easiest rule of thumb to remember and apply at the grocery store when shopping for foods with low calories high protein.
Answer: A food counts as genuinely low calorie and high protein when it delivers at least 10g of protein per 100 calories. Egg whites, white fish, shrimp, and nonfat dairy consistently clear that bar; nuts, oils, and most plant proteins don’t.
Breakfast: Foods With Low Calories High Protein to Start the Day
Breakfast is where most people default to carb-heavy, low-protein options. Swapping even one item fixes that.
- Egg white scramble (1 cup, ~2 eggs’ worth of whites): 14g protein, 60 calories
- Nonfat Greek yogurt (170g) with cinnamon: 17g protein, 100 calories
- Skyr with berries (170g): 19g protein, 110 calories
- Low-fat cottage cheese (½ cup) with sliced tomato: 12g protein, 90 calories
Pairing any of these with a small serving of oats or fruit keeps the meal under 300 calories while hitting 25–30g of protein — a realistic per-meal target if you’re spreading a daily goal across three meals.
Lunch and Dinner: Building a Plate Around Lean Protein
Lunch and dinner carry the most room for error, since sauces, oils, and portion creep add calories fast without adding protein. The table below ranks the most reliable foods with low calories high protein for these two meals, sourced from the USDA FoodData Central database.
| Food (cooked, 100g) | Protein | Calories | Protein per 100 kcal |
|---|---|---|---|
| Shrimp | 24g | 99 | 24.2g |
| Cod | 18g | 82 | 22.0g |
| Chicken breast (skinless) | 31g | 165 | 18.8g |
| Turkey breast (skinless) | 30g | 135 | 22.2g |
| Tuna (canned in water) | 26g | 116 | 22.4g |
| Tofu (firm) | 8g | 76 | 10.5g |
Answer: Shrimp and cod have the highest protein density of any common food, at roughly 22–24g of protein per 100 calories. Both cook in under 10 minutes, which makes them practical weeknight anchors, not just spreadsheet winners.
Simple Lunch and Dinner Combos
- Grilled chicken breast + large salad + vinegar-based dressing — ~35g protein, ~280 calories
- Baked cod + steamed vegetables + lemon — ~32g protein, ~180 calories
- Shrimp stir-fry with peppers and a splash of soy sauce — ~25g protein, ~220 calories
- Turkey breast wrap in a low-carb tortilla with greens — ~30g protein, ~260 calories
If you want a full week mapped out instead of building it meal by meal, the 7-day protein diet plan for weight loss does that legwork for you.
Snacks: Foods With Low Calories High Protein Under 100 Calories
Snacking is where a good day of eating usually falls apart. Keeping a short list of foods with low calories high protein on hand removes the decision fatigue that leads to chips or crackers instead.
- Hard-boiled egg (1 large): 6g protein, 78 calories
- Light string cheese (1 stick): 6g protein, 50 calories
- Turkey jerky (1oz): 13g protein, 70 calories
- Shrimp (3oz, cooked): 17g protein, 85 calories
- Nonfat Greek yogurt (100g, unsweetened): 10g protein, 59 calories

Comparison: Animal vs. Plant Sources
Plant proteins carry a structural disadvantage when it comes to foods with low calories high protein — legumes bring carbs, and many plant fats dilute the ratio. Seitan is the exception, behaving more like lean meat nutritionally. If plant-based eating is the priority rather than a secondary constraint, cross-reference this list with a best protein sources for fat loss comparison, since the “best” source shifts once you’re not optimizing purely for calories.
Common Mistakes People Make With Foods With Low Calories High Protein
- Treating peanut butter, nuts, and granola as “diet” foods because they’re marketed as high protein
- Frying or breading lean proteins, which can double the calorie count while adding almost no protein
- Only checking protein grams and ignoring the calorie cost behind them
- Skipping meals and trying to “catch up” on protein late in the day, which usually backfires on hunger
- Guessing at a daily target instead of calculating one
Pro Tips
- Cook proteins in bulk on a set day — grilled chicken, baked cod, and hard-boiled eggs all hold up well for 4–5 days refrigerated
- Grill, bake, steam, or air-fry; avoid pan-frying in oil or butter, which adds 100–120 calories per tablespoon
- Keep 2–3 “under 100 calorie” options stocked at all times to close snack-time gaps
- Aim for roughly 25–35g of protein per meal rather than back-loading it at dinner
- Log your intake for two weeks so you know your typical meals without tracking forever
How Much Protein Do You Actually Need?
Research from the International Society of Sports Nutrition puts protein needs for people actively losing fat or building muscle at roughly 1.2–2.2g per kilogram of body weight per day, depending on training intensity — noticeably above the general RDA of 0.8g/kg. That range is exactly why a rotating list of foods with low calories high protein matters more than a single “best food” — hitting 1.2–2.2g/kg requires variety across meals, not one hero ingredient. Rather than guessing, run your numbers through the protein calculator for weight loss to get an exact daily target, then use the meal breakdowns above to hit it.
Bottom Line
Foods with low calories high protein aren’t a mystery once you organize them by meal instead of by category: egg whites and Greek yogurt for breakfast, shrimp and cod for lunch or dinner, and jerky or hard-boiled eggs for snacks. Build your day around the options above, avoid the frying and portion mistakes that quietly add calories, and check your own target with a calculator instead of guessing.
FAQ
What is the single best food with low calories and high protein?
Egg whites and shrimp both top the list, delivering 21–24g of protein per 100 calories with almost no fat.
Can you get enough protein without eating meat?
Yes — nonfat Greek yogurt, cottage cheese, tofu, and seitan can all contribute meaningfully, though most plant sources have lower protein density than lean animal sources.
How many low-calorie high-protein foods should I eat per day?
Spread 3–4 servings across your meals and snacks, targeting roughly 25–35g of protein per meal, depending on your total daily protein goal.
Does cooking method really change the calorie count that much?
Yes. Pan-frying in oil can add 100–120 calories per tablespoon used, which is often more than the food’s own calorie count.
Is Greek yogurt better than regular yogurt for this?
Generally yes — Greek yogurt is strained to remove liquid, which concentrates the protein and lowers the volume-to-protein ratio compared to regular yogurt.
What should I avoid on a low-calorie high-protein diet?
Watch out for peanut butter, whole milk, sweetened protein bars, and fried preparations — all get marketed as “high protein” but carry a poor protein-to-calorie ratio.
Individual protein needs vary based on body weight, activity level, and health status. Consult a registered dietitian or your doctor for personalized guidance, especially if you have kidney or metabolic conditions.
