So what is a high-protein, low-carb food? Anything that contains at least as much protein as net carbs (calculated when you subtract the fiber amount from the total carbs) will fit the bill, according to nutritionist Sonya Angelone, RD. And it's a super important macronutrient if you're trying to build muscles, which help boost your metabolism. 'Since protein moves more slowly through the stomach than carbohydrates and fat, it can contribute to feelings of fullness,' nutritionist Kelly Jones, RD, previously told WH. Bonus: These foods are great to keep on hand if you're eating a keto or low-carb diet. Even better? High-protein, low-carb foods that will ensure your meals are super satisfying. That said, some types are better than others (hello, complex carbohydrates like millet, chickpeas, and oats!), while the simple carbs in foods like store-bought cookies and cakes can spike your blood sugar quickly and keep you from feeling satisfied. While carbs may have a bad rap, not all should be thought of as evil or worthy of cutting from your diet completely.
