Since avocados are packed with nutrients and healthy fats that can stimulate weight loss, it’s no surprise that avocado oil acts in a similar fashion. When Penn State University researchers compared those who consumed monounsaturated-rich oils (like high-oleic canola oil or avocado oil) with those who consumed a flax-safflower oil blend, they found that those who used just three tablespoons of the monounsaturated-rich oil daily lost nearly two percent of their belly fat in just one month.
Blueberries are lousy with antioxidants, satiating fiber, potassium, and more, and according to researchers at the University of Michigan, the colorful fruits may also encourage weight loss. In a study of laboratory rats, scientists found that after 90 days the rats who consumed blueberry-enriched powder as 2 percent of their diet had less abdominal fat, lower triglycerides, lower cholesterol, and improved fasting glucose and insulin sensitivity, than the rats who didn’t consume any blueberry-enriched powder.
Though we singled out quinoa above, whole grains in general (we’re talking cereal, rice, pasta, and more) are conducive to weight loss, especially when they’re used in place of refined—white—grains. In fact, a study published in the American Journal of Clinical Nutrition found that substituting whole grains for refined grains in the diet increases calorie loss by reducing calories retained during digestion and speeding up metabolism. Unlike refined grains, whole grains are packed with satiating, heart-healthy fiber.
Although they're best known for containing potassium, bananas are also a great source of resistant starch, a type of starch that's important for weight loss. Your body digests resistant starch slowly—helping you feel full for longer—while simultaneously encouraging your liver to switch to fat-burning mode. And no need to wait for them to become completely ripe; bananas actually contain more of this calorie-torching ingredient when they're still a little green.
It’s time to focus on your lentil health. In one four-week Spanish study, researchers found that eating a calorie-restricted diet that includes four weekly servings of legumes aids weight loss more effectively than an equivalent diet that doesn’t include beans. Those who consumed the legume-rich diet also saw improvements in their “bad” LDL cholesterol levels and systolic blood-pressure. To reap the benefits at home, work lentils, chickpeas, peas and beans into your diet throughout the week.
Think of each almond as a natural weight-loss pill. A study of overweight and obese adults found that, combined with a calorie-restricted diet, consuming a little more than a quarter cup of the nuts can decrease weight more effectively than a snack comprised of complex carbohydrates and safflower oil—after just two weeks! (And after 24 weeks, those who ate the nuts experienced a 62% greater reduction in weight and BMI!) For optimal results, eat your daily serving before you hit the gym. A study printed in The Journal of the International Society of Sports Nutrition found that almonds, rich in the amino acid L-arginine, can actually help you burn more fat and carbs during workouts.

Like peanuts, avocados contain metabolism-enhancing monounsaturated fats that have been shown to reduce hunger. In fact, a study in Nutrition Journal found that participants who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterwards. What’s more? The trendy toast topping is also loaded with unsaturated fats, which seem to prevent the storage of belly fat, as well as satiating fiber and free-radical-killing antioxidants.
Another weight-loss-friendly substitute to keep in mind is favoring salsa over ketchup. While ketchup typically has around 19 calories and 4 grams of sugar per tablespoon, fresh tomato salsa has about 5 calories per tablespoon, no added sugar, and is packed with nutritious veggies. Tomatoes, for example, are loaded with fat-blasting fiber and vitamin C, a deficiency of which Arizona State University researchers associated with increased body fat and larger waists. If you can handle spice, toss some jalapenos in your salsa to rev up your metabolism. For more on how you can switch your metabolism into overdrive, check out the best ways to boost your metabolism!
One of the best ways to have a healthy diet is to prepare your own food and eat in regularly. Pick a few healthy recipes that you and your family like and build a meal schedule around them. If you have three or four meals planned per week and eat leftovers on the other nights, you will be much farther ahead than if you are eating out or having frozen dinners most nights.
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.
“Thirst and hunger cues feel similar, so it’s important to stay hydrated, especially if you’re trying to lose weight,” explains Moon. Yes, plain water is important, but 20 percent of our daily water intake comes from foods, she says. “Watermelon is 92 percent water, plus it is bursting with vitamins A and C and anti-inflammatory nutrients like lycopene,” she explains.
This often over-looked gem is loaded with protein, filling fats, and calcium to help you build and repair muscles, which can aid in weight loss. “It's fabulous with fruit, on whole grain toast, oatmeal or salads, but the super high protein content [13 grams per 1/2 cup serving!] helps to keep you full in between meals,” says Harris-Pincus. You can also use it in smoothies, in eggs, or in pancake batter. Just be sure to check labels and find a product that’s low in sugar.
These support bone health and have other possible benefits. Dairy products are the best sources of calcium, but you can also get it from fortified foods as well as canned salmon, sardines, dark leafy greens, and most tofu. If you can’t get the recommended 1,000 to 1,200 milligrams a day from food, take a calcium supplement. It’s hard to consume enough vitamin D from foods (the RDA is 600 to 800 IU a day, though other experts advise more). Thus, many people—especially those who are over 60, live at northern latitudes, or have darker skin—should consider taking a supplement.
