Recipe to Try: Hasselback Tex-Mex Avocados

Avocados are rich in monounsaturated fatty acids, dietary fiber, potassium and phytochemicals. People who eat avocados tend to have lower BMI, body weight and waist circumference than people who skip this green superfood, per a study in Nutrition Journal. While avocados are higher in calories than other fruits and vegetables, their satisfying fat and fiber combo may help you slim down. Add some to your salad, sandwich or taco night for a burst of creaminess and flavor.

2. Eggs

Recipe to Try: Muffin-Tin Quiches with Smoked Cheddar & Potato

Eggs are rich in high-quality protein, fats and essential nutrients, like vitamin D and choline. It's the protein, and the time of day we tend to eat them, that especially makes them a powerhouse for weight loss. Eating a high-protein breakfast promotes weight loss, because protein increases satiety while regulating hunger and appetite hormones, helping fend off your hunger until lunchtime. One study found that eating eggs for breakfast left people feeling more satisfied than those who had bagels—which helped them eat less throughout the day.

3. Beans

Recipe to Try: Better Three-Bean Salad

All beans are high in fiber, which is your friend when you're trying to lose weight because it helps you feel fuller longer, thus controlling hunger. Eating beans and legumes has also been linked with various other health benefits, including lowering blood pressure, reducing LDL cholesterol and reducing risk of cardiovascular disease. Beans are fairly low in calories and deliver protein as well. Try them in homemade veggie burgers, soups and salads.

4. Yogurt

Recipe to Try: Raspberry Yogurt Cereal Bowl

Yogurt is protein-packed and full of probiotics, which are good for gut health and may help your weight-loss efforts. Your gut health can impact your weight, and eating more fiber and probiotics helps keep your gut bacteria happy, which can be good for your metabolism (read more about your gut-weight connection). Go Greek for more protein; plus, research from Appetite found that consumption of Greek yogurt was associated with reduced appetite and increased satiety. Just keep an eye on added sugars in flavored yogurts, which only add calories. Instead, use fresh fruit to sweeten plain yogurt.

5. Salmon

Recipe to Try: Garlic Roasted Salmon & Brussels Sprouts

Salmon is a rich source of high-quality protein and provides plenty of "good" fats: omega-3 fatty acids. A diet rich in omega-3 fatty acids helped people feel more satisfied when they were watching their calories, per a study in Appetite. Eating salmon can be a delicious and versatile way to get your recommended two weekly servings of heart-healthy fish.

6. Fruit

Recipe to Try: Fresh Fruit Salad

Fruit gets a bad rap sometimes because it naturally contains sugar. But eating fruit can help you lose weight, especially when you swap in fresh fruit for processed foods or other unhealthy snacks. You'll get a naturally sweet treat, plus reap the benefits of fiber and antioxidants. A recent study published in the Journal of Nutrition found that higher fruit consumption was associated with lower risk of becoming overweight or obese, independent of vegetable or fiber intake—though including fruit as part of a healthy diet overall is always the best strategy.

7. Popcorn

Recipe to Try: Lemon-Parm Popcorn

As long as this popular crunchy treat isn't doused in movie-theater butter, it makes an excellent weight-loss snack. Not only is popcorn high in fiber, it even delivers some protein. A 1-ounce serving of air-popped corn (about 3½ cups) has 4 grams of fiber, almost 4 grams of protein and clocks in at 110 calories. This combination makes it a snack with staying power. Popcorn is filled with air, so you get a pretty large portion without a lot of calories. You can eat 3 whole cups of popcorn for only 100 calories.

8. Almonds

Recipe to Try: Mango-Almond Smoothie Bowl

Almonds are an excellent source of fiber, and they're high in protein. Eating foods with the one-two punch of fiber and protein can help you feel fuller longer—which makes it less tempting to reach for an unhealthy snack between meals.

Rich in vitamin E and a good source of heart-healthy mono- and polyunsaturated fats, almonds are a great choice to sprinkle over a salad or side dish. You can also use them in pesto in place of walnuts or pine nuts, top your morning granola with them, or simply keep a small bag in your purse as an emergency snack.
