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.

To jumpstart your weight loss, we’ve selected some nutritious eats, like salsa, that are lower-calorie substitutes for less healthy choices (we’re looking at you, ketchup). And other weight loss foods, such as watermelon, contain certain compounds that have been scientifically proven to reduce the size of your waist and help reduce body fat. Scroll down below for a list of a few dozen best weight loss foods, and get even more health-conscious inspiration from this list of these dinner ideas that don’t need a recipe!
Cheese isn’t traditionally thought of as something you consume to encourage weight management, but calcium-rich Parmesan, when eaten in moderation, can help stave off sugar cravings that can easily lead to weight gain. How does that work, you ask? The native Italian cheese contains the amino acid tyrosine (a building block of protein) which has been shown to encourage the brain to release dopamine without any unhealthy insulin spikes. What’s more? The combination of calcium and protein found in dairy products such as Parmesan has been found to increase thermogenesis—the body’s core temperature—and thus boost your metabolism.

Cutting carbs altogether can often cause a guilt-ridden binge that will leave you unmotivated and packing on the pounds. Instead of prohibiting yourself from eating the foods you love, set a carb curfew. “For dinner, contestants always have a high-protein, high-fat meal with plenty of fibrous veggies,” Chris Powell of ABC’s reality series Extreme Weight Loss tells us in Chris Powell’s Behind-The-Scenes Extreme Weight Loss Tips. “If they have a post-dinner snack, they stick to protein-rich, high-fat foods like almonds or 2 percent milkfat string cheese.” Nixing carbs at night flips the fat-burning switch by increasing the amount of fat-burning hormones released while we’re asleep, Powell adds.

Is there anything avocados can't do? This creamy superfood (loaded with monounsaturated fats, potassium, magnesium, folate, and vitamins C and E) has been linked to improved vision, good heart health, and a reduced risk of certain cancers. And avocados can also help whittle your middle: according to one study, people who regularly consume them weigh less and have smaller waists than those who do not. Another study found that women who eat half an avocado at lunchtime might experience reduced food cravings later in the day.

Have a small, protein-heavy breakfast. Kickstart your day with a protein filled breakfast that will give you energy (and keep your blood sugar up) for the rest of the day. Aim for a breakfast that is 400 calories and eat it every morning at around the same time. Go for variety and rotate two to three options. Pair your breakfast with unsweetened tea or a glass of water with lemon.[6]

^{Friends are helpful not only because they can double as workout buddies or help hold you accountable for appropriate diet and exercise, but also because they’re a surefire way to combat gut-growing feelings of loneliness. A study in the journal Hormones and Behavior  found that those who feel lonely experience greater circulating levels of the appetite-stimulating hormone ghrelin after they eat, causing them to feel hungrier sooner. Over time, folks who are perennially lonely simply take in more calories than those with stronger social support networks, so be sure to fit time with pals into your busy schedule.}

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.

Water is a weight loss ally in a number of ways. For starters, if sipped prior to a meal it can help ensure you eat less. A British study published in the journal Obesity that asked participants to chug 16 ounces of H2O prior to eating found said participants lost an average of 2.87 pounds in 90 days—which translates to nearly 12 pounds in a year! Water helps you blast even more fat because it is a much better beverage choice than diet soda or fruit juice, both of which are full of artificial sweeteners that can pack on belly fat super fast.

Not only is drinking lemon water a healthy, low-calorie alternative to soda or juice, but lemons themselves have also been shown to contribute to weight loss. Just one of the citrus fruits contains an entire day’s worth of vitamin C, a nutrient that has the power to reduce levels of cortisol, a stress hormone that triggers hunger and fat storage. Additionally, lemons also contain polyphenols, which researchers say may ward off fat accumulation and weight gain. Believe it or not, even the peel is beneficial because it is a potent source of pectin—a soluble fiber that’s been proven to help people feel fuller for longer. According to a study published in the Journal of the American College of Nutrition, participants who ate just 5 grams of pectin experienced more satiety.

Like a marathoner stretching before the big run, eating half a grapefruit before a meal can enhance your body’s fat-burning performance. A study published in the journal Metabolism found that this “warm-up” tactic can help whittle your middle—by up to an inch—in just six weeks! The scientists attribute the powerful effects to the grapefruits’ fat-zapping phytochemicals. The fruit can interact negatively with certain medications, so as long as you get the green-light from your M.D, plan to have half of a grapefruit before your morning meal and add a few segments your starter salads to reap the benefits.
