Understanding the 'Just Protein' Concept
While it's nearly impossible for a single, unprocessed food to contain only protein and nothing else, the term 'just protein' in snacking typically refers to items with an extremely high protein-to-carbohydrate ratio. These snacks are often favored by those on ketogenic, low-carb, or high-protein diets because they provide the satiating benefits of protein without a significant carb load. The key is to select whole foods and minimally processed options to avoid added sugars and unwanted ingredients. This guide explores various categories of snacks that come closest to this ideal.
Animal-Based Pure Protein Snacks
Animal products are some of the most reliable sources of high-quality, zero or near-zero carb protein. Many are conveniently portable and require little to no preparation.
Jerky (Beef, Turkey, and Salmon)
Jerky is a classic grab-and-go protein option. It is meat that has been trimmed of fat and dried, resulting in a portable, shelf-stable snack. A single ounce of beef jerky can contain 9-12 grams of protein. It's crucial to select low-sugar varieties, as many store-bought brands contain excessive added sugars and sodium. Jerky from turkey or salmon is also available and offers excellent protein counts.
Hard-Boiled Eggs
A perfect, simple snack, one large hard-boiled egg offers about 6 grams of complete, high-quality protein and less than 1 gram of carbohydrates. Eggs are incredibly versatile and can be made in batches for easy meal prep. They also provide essential nutrients like choline, vitamin D, and vitamin B12. You can eat them plain or sprinkle with salt, pepper, or other seasonings for added flavor.
Cheese
Many cheeses are naturally very low in carbohydrates and rich in protein. String cheese is an excellent pre-portioned, portable choice, providing about 7 grams of protein per stick. For an even higher-protein, zero-carb option, consider cheese crisps or baked parmesan crisps. An ounce of cheddar cheese also offers around 6 grams of protein.
Deli Meat Roll-ups
For a quick, refrigerator-friendly snack, roll up a slice of low-sodium turkey, chicken, or ham with a slice of cheese. These are like sandwiches without the bread, maximizing protein while keeping carbs minimal. Adding a pickle spear or cucumber can provide extra crunch and hydration.
Canned Tuna or Salmon
Canned fish is a powerhouse of protein and omega-3 fatty acids. A 3-ounce serving of tuna can provide over 20 grams of protein. Single-portion pouches of tuna and salmon are widely available, making them highly portable. Enjoy it straight from the can, or mix it with some mustard and dill for a simple, savory snack.
Plant-Based 'Almost' Just Protein Snacks
Plant-based diets also offer several high-protein, low-carb options, often accompanied by fiber and healthy fats.
Edamame
These immature soybeans are a fantastic source of plant-based protein. A half-cup serving of shelled edamame contains about 8 grams of protein and is considered a complete protein source, containing all essential amino acids. It also provides fiber, which helps promote fullness. Edamame can be steamed and sprinkled with sea salt for a quick and satisfying snack.
Tofu
Tofu, made from soybeans, is a versatile plant-based protein. A 3-ounce serving of firm tofu provides 9 grams of protein and can be cut into cubes, marinated, and baked for a crispy, easy-to-carry snack. It offers a significant protein boost for any diet.
Seeds
Seeds like pumpkin and sunflower seeds pack a solid protein punch along with healthy fats. An ounce of shelled pumpkin seeds contains 8 grams of protein, while sunflower seeds offer 6 grams per ounce. They are a great portable snack for on-the-go energy.
Dairy-Based High-Protein Snacks
For those who consume dairy, several options provide a convenient protein boost.
Greek Yogurt and Cottage Cheese
Unsweetened Greek yogurt and cottage cheese are staples in high-protein snacking. Greek yogurt is strained to remove excess liquid, resulting in a higher concentration of protein. A 3/4-cup serving of plain, nonfat Greek yogurt can offer up to 17 grams of protein. Cottage cheese is also very high in protein, with a half-cup serving containing about 12 grams. These can be enjoyed plain, mixed with seeds, or with a few low-carb berries for sweetness. Both are rich in casein protein, which digests slowly, prolonging feelings of fullness.

Tips for Smart High-Protein Snacking
- Portion Control: Even high-protein, low-carb snacks like nuts and seeds can be high in calories. Measure your servings to stay on track with your goals.
- Read Labels Carefully: Many packaged snacks, including jerky and protein bars, hide sugars and additives. Always check the nutrition facts for hidden carbs.
- Combine and Customize: Pairing protein with other macros can enhance the nutritional value. For instance, add a tablespoon of nut butter to celery sticks or mix nuts into Greek yogurt.
Conclusion
While a snack with just protein is a conceptual ideal, a variety of whole foods come remarkably close. From the convenience of jerky and hard-boiled eggs to the plant-based goodness of edamame and tofu, the options are plentiful for satisfying hunger and meeting nutritional needs without an excess of carbohydrates. By focusing on these wholesome choices and practicing careful portion control, you can ensure your snacking habits support your health and fitness objectives.
