Based on the heart-healthy lifestyle of Greece, Italy, Spain, and Portugal, Mediterranean-style diets include healthy fats such as avocados, olive oil, nuts, and fish at least twice a week, plenty of beans, fruit, leafy greens, and whole grains, and even a daily glass of red wine. You can eat cheese in moderation, but limit the red meat to once or twice a week.

How it works for weight loss: Though this diet’s primary appeal is in its numerous health benefits—it can lower your risk of both chronic disease and cognitive decline—it can also lead to weight loss if you limit your calorie intake to 1,500 a day or less. Studies have found that following either a traditional Mediterranean diet or a low-carb version of it can result in weight loss of about 5-10% of body weight over 12 months. And that weight stays off—a recent British study found that for people who had lost large amounts of weight, those who consumed a Mediterranean-style diet were twice as likely to keep it off. “This diet is easy to maintain, because the food is delicious!” says Beaver.

The low-sodium Dietary Approaches to Stop Hypertension (DASH) Diet was designed as a way to help people control their blood pressure without using drugs, though a few books have used it as a basis for a weight-loss diet. DASH emphasizes fruits, vegetables, whole grains, and low-fat or nonfat dairy and limits saturated fat and dietary cholesterol.

How it works for weight loss: You will certainly improve your health with this diet, and if you restrict calories while following DASH’s heart-healthy rules, you can lose weight and lower your blood pressure. A recent study found of obese older adults found that those who followed the DASH diet lost weight and decreased body fat, along with many other health benefits. “DASH is one of my favorite diets,” says Meridan Zerner, R.D., a dietitian at the Cooper Clinic in Dallas. “You’re getting the anti-inflammatory, high fiber, heart-healthy benefits, and if you use a personalized, calorie-limited plan, you can absolutely lose weight.”

There are a few different ways to do the intermittent fasting plan: Some people eat whatever they want 5 days a week, then consume a very low calorie diet (usually around 500 calories) on the other 2 days; others restrict their eating to an 8-hour window every day. Say, eating unlimited food between 8 a.m. and 4 p.m., and fasting for the other 16 hours.

How it works for weight loss: By limiting your overall calories consumption, you’ll take off the pounds, says Zerner, who points out that there is some evidence that this diet can also increase your metabolism rate and have other positive health effects. A 2015 meta-study found that people who did intermittent fasting lost about the same amount of weight as those who did a regular calorie-restricted diet.

There’s nothing better than a warm bowl of pumpkin soup on a cold autumn day. Combine your roasted pumpkin with some onion, garlic, vegetable broth, and a few spices, and give it some time to simmer away. Pair it with a few slices of fresh bread to turn it into something sublime.
