Not all carbs are created equal, and while some people need to watch their intake, whether to manage type 2 diabetes or support other health goals, carbs themselves are not the enemy. The real key is choosing foods that provide lasting energy and nourishment.
That's where low-carb, high-protein foods come in. They are filling and nutrient-dense, giving you more vitamins, minerals, and fiber for a satisfying solution. Protein supports healthy muscles and keeps your metabolism running smoothly, while fiber helps with digestion and keeps you feeling satisfied between meals. Including these foods makes it easier to maintain a balanced, sustainable diet without feeling deprived.
But the dietitians in the Good Housekeeping Institute Nutrition Lab stress that no single food group can do it all. Even the best low-carb, high-protein choices work best when they are part of a diet that includes a variety of foods from all food groups. Here are some of our favorite low-carb, high-protein foods that actually keep you full.
Sardines
Canned sardines are more than just a trend, they’re a protein-packed powerhouse. A half can provides about 11 grams of protein, plus selenium to support immunity, choline for brain health, and electrolytes like potassium and magnesium to balance sodium. Try them on toast, in salads, or blended into spreads for a quick, nutrient-dense boost. Their omega-3 fats also support heart and brain health, making them a true multitasker in your diet.
