Black Beans
Black beans are chock full of protein and fiber – the two most important ingredients that keep you satisfied for a long time after your meal. The dark color of black beans also means that they contain flavonoids, which some studies show helps to reduce stomach fat.
Grapefruit
We all know the stereotypical picture of someone on a diet starts with half of a grapefruit for breakfast – and don’t you dare add sugar! Well, it’s a stereotype for a reason – it works! Grapefruits are mostly made from water, meaning that they keep you full while also being super low-calorie. Don’t eat toooo many though – all that acid is only good in moderation.
