1 Apples
Apples are so famous for being loaded with anti-cancer compounds that their ability to restore the microbial balance in your gut is often overlooked. The fiber and polyphenols in the skin and flesh of whole apples are fermented in the colon where they fuel the growth of healthy bacteria, which helps to reduce the inflammation that contributes to obesity.

2 Berries
You don't need to be convinced that a handful of blueberries is healthier than a handful of Gummy Bears. Snacking on berries before dinner could be a simple method for weight management.

3 Grapefruit
A half of a grapefruit contains only about 40 calories and nearly 4.5 grams of pectin, a soluble fiber known for its ability to reduce cholesterol levels. Due to its antioxidant components, grapefruit has been shown in studies to be associated with greater rates of weight loss.

4 Avocado
It's easy to forget that avocados are technically fruits, but regardless of their designation, avocados have also been found to support weight loss. The fiber and monounsaturated fats from eating one avocado daily improve healthy gut microbiota and help with weight loss. Eating one avocado a day as part of a moderate fat diet was associated with decreased hunger as well as lowering LDL cholesterol, especially the small-dense LDL that's most dangerous to heart health.

5 Watermelon
Eating your water is a good way to fill up before a meal. That's where watermelon comes in. Even though it's sweet, watermelon is mostly water, about 94% water. No wonder it's only about 40 calories per cup and a good dessert option for people looking to lose weight.
