8. Avocados

The creamy flesh of avocado is not only tasty, but also rich in healthy monounsaturated fat and fiber. Avocados are one of the best filling foods so you will experience less hunger while taking fewer calories. Avocados also contain oleic acid, a type of fat that will tell your brain that your tummy is full. But do remember that, while they are highly nutritious, avocados are high in calories, so stick to eating only half slice each time.
