Low-Sugar Low-Carb Foods

Eating high-protein, low-sugar foods can prevent spikes in blood sugar and satisfy hunger longer than foods that are high in simple carbohydrates, according to the Harvard School of Public Health. Choosing a wide of variety of foods with different flavors and textures can help individuals stick to a diet that restricts sugar and carbohydrates.

Fruits and Vegetables

Increasing the amount of fruits and vegetables an individual consumes on a daily basis reduces his risk of developing heart disease, reports the Harvard School of Public Health. To limit carbohydrates, choose non-starchy vegetables. Examples include leafy greens, such as lettuce and spinach, and cruciferous vegetables, such as broccoli and cabbage. A balanced diet should include fruit. Choose fruit and fruit juices that are low in sugar, such as lemon and lime juice, grapefruit and berries. For example, a 1/2 cup serving of blackberries contains less than 7 grams of carbohydrates and 4 grams of sugars.

Meat and Poultry

Red meat, pork and poultry contain high amounts of protein and no carbohydrates. However, fatty cuts of meat should be avoided to limit the daily intake of saturated fat. The Harvard School of Public Health recommends that individuals avoid processed meats to reduce their chance of developing colon cancer. For those who prefer beef, lean options include eye of round roast, top sirloin steak, bottom round roast and mock tender steak.

Fish and Seafood

Fish and seafood are a good source of protein that is also low in carbohydrates and fat. For example, a 3-ounce serving of boiled shrimp provides approximately 19 grams of protein, 1 gram of carbohydrate and 1 gram of fat. A 5-ounce can of light tuna packed in water provides about 26 grams of protein, 1/2 gram of fat and no carbohydrates. Options that are readily available include cod, crab, flounder, pollock, salmon, shrimp, snapper, tilapia and tuna.

Nuts and Seeds

When enjoyed in moderation, nuts and seeds can add variety to a low-carbohydrate diet. They provide protein, fiber, essential fatty acids and many nutrients that contribute to a healthy diet. Popular options include almonds, peanuts, pecans, pumpkin seeds, sesame seeds, sunflower seeds and walnuts. To limit sodium, avoid products that are smoked or salted.

Dairy Products

Before purchasing dairy products, read the labels to determine the amount of carbohydrates and sugar the products contain. Low-carbohydrate options include eggs, cheese and cream. Select reduced-fat or fat-free varieties to limit the consumption of saturated fat.
