“Cilantro has numerous health benefits and is packed with nutrients such as fiber, iron, thiamine, zinc, folate, phosphorous, folate, vitamin K, and more,” says Ellis. Plus, it has a great aroma and flavor that screams summer! Cilantro may increase the production of digestive acids, which can help stimulate the gut to move waste out. A healthy digestive tract is key for weight loss, says Ellis.

“This sweet tropical fruit is the perfect ingredient for summer smoothies and juices,” says Beth Aldrich, a certified holistic health and nutrition counselor, and author of the book Real Moms Love to Eat. “It contains the proteolytic enzyme bromelain, which aids in the digestion of protein and blood clot formation. As an anti-inflammatory super food, pineapple can help reduce swelling and in turn, you'll have a flatter belly.”

Also known as yam or yambean, this Mexican turnip is a great source of fiber, says Dr. Jaime Schehr, a registered dietitian in New York City. “This plant is great for weight loss due to its high fiber to sugar ratio (a whopping 32g of fiber per medium jimaca—that’s almost an entire day’s worth). They are also a good source of potassium, an essential mineral in maintaining water balance in our body.”

Ceviche is a wonderful lean protein source found on many Mexican menus throughout the summer months, and it’s easy to make at home, says Sharon Richter, a registered dietitian in New York City. Depending on what type of fish is used, ceviche can range between 120-175 calories per serving. (And word has it that Lady Gaga fuels up on ceviche while on tour).

Bitter Melon

This bitter and slightly sweet melon is typically found in Asian markets and helps improve digestion and lower blood sugar. “Keeping blood sugar under control is important if you want to lose weight,” says Nicole Kuhl, a clinical nutritionist and Director of Nutrition at Lifespan Medicine. “Too much sugar in the blood stream sends a signal to the pancreas to release the fat storing hormone insulin. By keeping your blood sugar under control, you will reduce the likelihood of storing calories as fat.” Can’t stomach the bitterness? Try soaking it in chilled saltwater for a few hours prior to eating (raw or cooked).

“Mangoes are a great way to satisfy a sweet tooth and to help to ward off other cravings,” says Rania Batayneh, MPH, a nutritionist and owner of Essential Nutrition for You. Mangoes are high in fiber, magnesium, antioxidants, and iron (making them a great snack for women who may have iron deficiency or anemia), says Batayneh. “And because mangoes aid in digestion, you want to focus on eating the fruit versus just drinking the juice.”

Purple Carrots

You know carrots are good for you, but did you know that purple carrots are even better? “Purple carrots contain all of the phytochemicals found in orange carrots, and they also contain anthocyanins, which are potent antioxidants,” says Dr. Robert Rey, a Beverly Hills plastic surgeon, reality TV star of Dr. 90210, and author of Body by Rey.This sweet, crunchy snack is loaded with powerful anti-aging properties and protects against damage caused by oxidation (free radicals).

This fiber- and potassium-rich fruit makes the perfect summer snack. At around 170 calories for 8 oz, you can eat them alone, in salads, in cereals, or wrapped in prosciutto (just don’t grab a Fig Newton—you’ll get more nutrition and less fat from the actual fruit).

“Research published in the Journal of Nutrition in 2006 found that the type of DHA omega-3 oil found in salmon may have an ‘anti-obesity effect’ by preventing an increase in fat cells, causing death of pre-fat cells, and promoting the breakdown of fat in the body,” says Maleeff. Not sure how to prepare it? Try any (or all) of these five tasty salmon recipes.

“Packed with important nutrients including vitamins A and C, potassium, and iron, one medium peach (only 38 calories) provides nearly 2 grams of fiber,” says Lauren O’Connor, a registered dietitian in Los Angeles, California. “A peach provides gentle laxative and diuretic properties; and thanks to it's beta carotene, it also helps your skin stay fresh and bright.” (They also make the perfect frozen treat! Try this recipe for pomegranate-peach-sicles).

“Peas have higher protein and iron levels than most vegetables, so they can be a good source of nutrients—and an alternative to non-animal foods which tend to be higher in saturated fat,” explains Vicario.

Did you know turnips could help you shed belly fat? Their high vitamin C and phytochemical levels help detoxify your body—and too many toxins in the body can lead to fat accumulation around your waist, says Maleeff. At only 34 calories and 8 grams of carbohydrates per cup (vs. a potato’s 113 calories and 26 grams of carbohydrates), try making mashed turnips instead of mashed potatoes for a nutrient-dense, low-calorie alternative, suggests Maleeff.

Rich in vitamin C and phytochemicals with antioxidant and anti-inflammatory properties, grapes may also protect against Type 2 diabetes, says Kara Ellis, a registered dietitian in New York City. “Grapes also have a high water content, making them a refreshing summer snack that helps you feel full and satisfied (1 cup of fresh grapes contain only 100 calories).”

“Sweet potatoes are a great source of dietary fiber, which helps to reduce blood sugar and insulin spikes, ultimately reducing belly fat,” explains Shana Maleeff a dietitian and fitness professional in New York City. Maleeff suggests substituting a sweet potato for potato salad, potato chips, or mashed potatoes at BBQs to save hundreds of calories. (We also love this recipe for mashed roasted sweet potatoes).

“Salsa is low in calories and tastes great on all kinds of healthy foods (vegetables, salads, poultry, and fish). It has antioxidants, such as lycopene, which aid in cellular health. Use salsa in place of other high-calorie dips such as hummus, onion dips, and cheese dips and you’re guaranteed to cut calories,” says Ellis. Make your own at home with this easy recipe for spicy corn salsa.

"For about 150 cal per 3.5 oz serving, arctic char joins the ranks of heart-healthy foods as a rich source of omega-3 fatty acids. Choosing fish over red meat reduces saturated fats in the diet and may help lower risk of heart disease and cancers,” says O’Connor. High in two types of healthy, mood-enhancing omega-3’s (EPA and DHA) this high-protein, low-calorie fish makes a great main course.

Full of fiber and heart-healthy fats (including omega-3’s, which have shown to have metabolic-boosting benefits), walnuts are great to crunch on instead of “bad” fat-filled and salted potato chips, says Maleeff. Just watch your portion size since nuts are high in calories. (We recommend tossing a handful into a salad to add crunch and flavor).

Plus, sardines are satiating and packed with protein, says Richter.

“Bananas contain a small amount of fiber and resistant starch, which have received recent attention for their potential role in boosting weight loss,” says Ellis. Snacking on bananas is easy, convenient, and low cal. They’re also a great source of potassium, which can be lost in sweat during tough workouts or on hot summer days. Plus they make for nice drinks, like the Jamba Juice Triple Revitalizer with carrot and orange juice.

In addition to being nutritious, low-cal and full of fiber, cabbage is also a top source of sulfur, a mineral our bodies use to produce the natural hair-and-nail strengthener keratin, says Rey. To stay slim and enjoy more beautiful hair and nails, whip up some vinegar-based coleslaw. Just stay away from creamy coleslaw; it can contain a whopping 19 grams of fat per cup!

“At a tiny 20 calories for every 3 cups, arugula provides an excellent source of folate, vitamins A and C, and more than 100 percent of your daily vitamin K needs,” says Rey. Not only is it a great weight-loss food, arugula can also help reduce your risk of bone fractures this summer: A recent Framingham Heart study found that people who consumed approximately 250 micrograms per day of vitamin K had a 35-percent lower risk of hip fractures compared to those who consumed just 50 micrograms per day, says Rey.

“One cup of shredded Romaine lettuce is a mere 10 calories,” says Victoria Shanta Retelny, author of The Essential Guide to Healthy Healing Foods. It’s also full of vitamins and has more fiber than it’s other leafy counterparts, so if you are hungry, toss up a salad with a drizzle of vinegar and oil for a filling, light meal or snack.

“High in flavor, vitamin K, manganese, and iron, thyme is an herb with volatile oils, which support cells (especially in the brain) and protect membranes which can suffer when you diet,” says Cohn. “Not to mention, thyme is delicious, and keeping your food tasty is a key to weight loss.” We agree!

“Turkey is a great source of B vitamins, selenium, and lean protein,” says Ellis. Grill up a turkey burger (be sure to check for 90-percent lean—or moreon the label) instead of a full-fat hamburger for a lighter, leaner option.

“Although available year–round, celery is best in the summer,” says Ellis. This super low-calorie food is also an excellent source of vitamins K and C, and a good source of many other essential nutrients such as dietary fiber, folate, potassium, and thiamine. “Crunching on celery is one of the oldest diet tricks because it may help decrease overall calorie consumption and aid in healthy digestion.”

Lemons and Limes

Both lemons and limes are excellent sources of Vitamin C, says Ellis, but it’s their flavor that aids in weight loss the most. “We’ve all been told to drink lots of water, but sometimes water’s lackluster taste causes us to turn to other beverages. Add lemon or lime juice to boost your water’s flavor and can help you drink more—staying hydrated may help suppress appetite, says Ellis.

Wheat often gets a bad rap when it comes to weight loss, but it can offer vital nutrients that are helpful for dieters, says Cohn. The whole grains found in wheat (such as bulgur) are great sources of energy, as they are high in B vitamins, minerals, and fiber.

A great energy source and naturally high in soluble fiber (the goopy, gelatinous fiber that promotes good digestion), oats are a great weight-loss food since so many diets cause constipation, says Cohn. Eat them as a nourishing hot breakfast cereal or dry as granola.

This way, you won’t be tempted to tap into those greasy potato chips too soon after dinner. Prunes are also high in vitamins and de-bloating potassium (to keep those abs looking fab!),” says Lauren Slayton, a nutritionist in New York City. Since you can easily toss them into your beach bag, prunes make the perfect summer snack!
