The healthiest fruits with the greatest effect on weight maintenance were chock full of flavonoids called anthocyanins, and blueberries top this list.
It's great if an apple a day can keep the doctor away, but it's an added bonus if it also helps keep you trim! Apples are rich in flavonoid polymers and are also packed with fiber, making them one of the healthiest fruits for weight loss
Fiber fills you up and creates satiety, so pears and apples give you a lot of bang for your buck.
Strawberries help maintain weight for the same reason as blueberries: They're rich in anthocyanins. Start incorporating one cup of strawberries a day into your diet
Peppers are in fact a fruit. Ranking up there with the healthiest fruits, they can also help put the brakes on weight gain when eaten daily, according to the research.
