The best high-protein, low-carb foods are chicken breast, turkey, fish, shellfish, eggs, cottage cheese, plain Greek yogurt, tofu, tempeh, and edamame. Most contain 15 to 25 grams of protein per serving with fewer than 5 grams of carbohydrate. They form the backbone of any blood-sugar-friendly meal plan because they keep you full, blunt glucose spikes, and preserve muscle during weight loss.
Why High-Protein, Low-Carb Foods Help Blood Sugar
Carbohydrates have the fastest and largest effect on blood glucose. Protein has a small, slow effect (some amino acids convert to glucose over hours), and dietary fat has almost none. Building meals around protein and non-starchy vegetables — with carbohydrate as a smaller side — flattens the post-meal glucose curve dramatically. This pattern is the foundation of every effective prediabetes diet plan.
Protein also boosts satiety more than carbs or fat per calorie, which makes weight loss easier — and weight loss is the single most powerful tool for improving insulin sensitivity.
Top Animal Proteins (Under 1 g Carb)
Chicken Breast
3 oz cooked: 26 g protein, 0 g carbs, 3 g fat. The gold standard. Versatile, affordable, available everywhere.
Turkey Breast
3 oz cooked: 25 g protein, 0 g carbs, 1 g fat. Even leaner than chicken.
Tuna (Canned in Water)
3 oz: 20 g protein, 0 g carbs. Cheap, shelf-stable, ready in seconds.
Salmon
3 oz cooked: 22 g protein, 0 g carbs, 6 g fat (mostly omega-3s).
Shrimp and Other Shellfish
3 oz cooked shrimp: 20 g protein, 0 g carbs. Mussels and oysters carry a tiny amount of glycogen carbs (3-4 g per 3 oz).
Eggs
1 large egg: 6 g protein, 0.4 g carbs, 5 g fat. Two eggs provide roughly 12 g of protein.
Lean Beef and Pork
3 oz sirloin: 25 g protein, 0 g carbs. Pork tenderloin: 23 g protein, 0 g carbs.
Top Dairy Proteins (Low Carb)
Cottage Cheese
1/2 cup low-fat: 14 g protein, 4 g carbs. Excellent for breakfast or snacks.
Plain Greek Yogurt
6 oz nonfat: 17 g protein, 6 g carbs (lactose). Avoid flavored versions which can add 15+ g of sugar.
Plain Skyr
5.3 oz: 17 g protein, 4 g carbs. Even thicker and slightly tangier than Greek yogurt.
Hard Cheeses
1 oz cheddar: 7 g protein, less than 1 g carb, 9 g fat. Useful in moderation.
Top Plant Proteins
Tofu (Firm)
3 oz: 8 g protein, 2 g carbs. Soaks up flavors well.
Tempeh
3 oz: 17 g protein, 9 g carbs (mostly fiber). Nutty flavor, denser than tofu.
Edamame
1/2 cup shelled: 9 g protein, 7 g carbs (4 g fiber). Best plant source under “low-carb” thresholds.
Seitan (Wheat Protein)
3 oz: 21 g protein, 4 g carbs. Avoid if gluten-sensitive.
Hemp Seeds
3 tablespoons: 10 g protein, 2 g carbs. Easy to sprinkle on salads or yogurt.

Building a Balanced Low-Carb Plate
Use these ratios for the most stable blood glucose:
- Half plate: non-starchy vegetables (cooked or raw)
- Quarter plate: high-protein food (4-5 oz cooked weight)
- Quarter plate: small carb portion (1/3 cup whole grain, 1/2 cup beans, OR 1/2 cup berries) — or skip carbs if very low-carb
- Add: 1-2 tablespoons healthy fat (olive oil, avocado, nuts)
Hidden Carb Traps
Many “protein” foods carry surprising amounts of carbohydrate:
- Breaded chicken or fish: the breading can add 15-25 g of carbs
- Teriyaki, BBQ, sweet chili sauces: 8-15 g of sugar per 2 tablespoons
- Honey-glazed ham or turkey: often 5-10 g sugar per slice
- Flavored Greek yogurt: 15-25 g added sugar
- Imitation crab: contains starch and sugar (about 13 g carbs per 3 oz)
- Protein bars: many contain 25-40 g total carbs
- Sweetened protein shakes: can hide 20+ g sugar
- Rotisserie chicken seasonings: some contain dextrose; check label
Special Notes
Kidney Disease
People with chronic kidney disease may need to restrict protein. Talk with your nephrologist before adopting a high-protein eating pattern.
Older Adults
Adults over 65 actually benefit from higher protein (1.0-1.2 g/kg/day) to preserve muscle and bone. The plate method still works — just slightly bigger protein portions.
Vegetarian and Vegan
Tofu, tempeh, edamame, seitan, and hemp seeds are the easiest plant proteins to fit into a low-carb plan. Lentils and beans are higher in carbs (15-25 g per half cup) but provide fiber that softens their glycemic impact — they may suit a moderate low-carb approach better than a strict one.
The Bottom Line
The best high-protein, low-carb foods are skinless poultry, fish and shellfish, eggs, cottage cheese, plain Greek yogurt, lean beef and pork, tofu, tempeh, and edamame. Build each meal around 25 to 35 grams of protein from this list, fill half your plate with non-starchy vegetables, add a small amount of healthy fat, and keep starchy carbs to a single small serving. This pattern keeps blood glucose steady, reduces hunger, supports muscle, and makes weight loss more sustainable. Watch out for hidden carbs in sauces and processed proteins, and work with your healthcare team or a registered dietitian to fine-tune protein targets if you have kidney disease or other special considerations.
