Avocado Please.

According to a new study, participants who ate half of a fresh avocado with lunch were 40% less hungry three hours later and 28% less hungry five hours later. Most of the fat content in avocados is monounsaturated fat and studies have shown that regularly consuming this type of fat can reduce levels of bad cholesterol in the blood, as well as reduce the risk of stroke and heart disease.
