“Fish is a great source of satiating protein and is typically lower in calories than other animal proteins,” says Maggie Moon, MS, RD, author of The MIND Diet. “Sardines are a sustainable seafood choice, which are packed with heart-healthy and brain-healthy omega-3 fats,” she says. These healthy fats can help decrease inflammation and improve your mood while dieting.
Diets to promote weight loss are divided into four categories: low-fat, low-carbohydrate, low-calorie, and very low calorie.[27] A meta-analysis of six randomized controlled trials found no difference between the main diet types (low calorie, low carbohydrate, and low fat), with a 2–4 kilogram weight loss in all studies.[27] At two years, all of the diets in the studies that reduced calories caused equal weight loss regardless of whether changes in fat or carbohydrate consumption were emphasized.[28]

Potatoes often get a bad rap, but when it comes to weight loss they're hard-to-beat sources of scale-dropping fiber. According to the Cleveland Clinic, sweet potatoes will up the insoluble fiber in your diet, keep you full longer, and you can bake and eat one for just 114 calories. Just watch what you load it with — instead of cheese or sour cream, opt for good-for-you fillings like black beans, tomatoes, and bell peppers.

The American Heart Association, World Cancer Research Fund, and American Institute for Cancer Research recommend a diet that consists mostly of unprocessed plant foods, with emphasis a wide range of whole grains, legumes, and non-starchy vegetables and fruits. This healthy diet is full of a wide range of various non-starchy vegetables and fruits, that provide different colors including red, green, yellow, white, purple, and orange. They note that tomato cooked with oil, allium vegetables like garlic, and cruciferous vegetables like cauliflower, provide some protection against cancer. This healthy diet is low in energy density, which may protect against weight gain and associated diseases. Finally, limiting consumption of sugary drinks, limiting energy rich foods, including “fast foods” and red meat, and avoiding processed meats improves health and longevity. Overall, researchers and medical policy conclude that this healthy diet can reduce the risk of chronic disease and cancer.[11][12]

A 2016 study found that garlic powder reduces body weight and fat mass among people with non-alcoholic fatty liver disease (NAFLD). Recent studies have also shown that garlic supports blood-sugar metabolism, and helps control lipid levels in the blood. What’s more? Eating garlic can help boost your immune system, help ward off heart disease, fight inflammation, increase memory retention, and lower blood pressure, so consider adding some to your next meal. At the very least, it is preferable over salt, which can lead to water weight gain and bloating.
Try a lower-calorie version. Use lower-calorie ingredients or prepare food differently. For example, if your macaroni and cheese recipe uses whole milk, butter, and full-fat cheese, try remaking it with non-fat milk, less butter, light cream cheese, fresh spinach and tomatoes. Just remember to not increase your portion size. For more ideas on how to cut back on calories, see Eat More Weigh Less.
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!
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.
