Lentils. High in protein, lentils can help prevent spikes in insulin levels that can cause your body to store excess fat.
Kale. This leafy green provides fiber, iron and calcium and it is a low calorie way to fill up.
Blueberries. A good source of antioxidants, blueberries have over 3.5 grams of fiber per cup, which can help to fill you up and keep your digestive system running smoothly.
Wild Alaskan salmon. An excellent source of omega-3 fatty acids, salmon can help improve insulin sensitivity, which helps build muscle; the more muscle you have, the more calories your body burns. Sardines are another good omega-3 and protein-rich fish option.
Steel-cut oats. An excellent source of fiber, eating steel-cut oats is a good way to fill up without a lot of calories.
Quinoa. A healthy alternative to white rice, quinoa can help curb hunger via its fiber and protein content.
Apples. A calorie-efficient way to curb hunger, apples contain antioxidants that may help prevent metabolic syndrome, a condition marked by excess belly fat.
Quinoa pasta. Unlike regular white-flour pasta, quioa is high in fiber and contains protein, making it more satiating, so you eat less. Try quinoa noodles in place of spaghetti.
Olive oil and avocados. Both contain heart healthy monounsaturated fats. Many people find that increasing their intake of healthy fats makes them feel fuller while keeping insulin - which helps conduct fat into the cells for storage - low and steady.
