Chili Peppers
Chili Peppers contain a chemical, known as Capsaicin that helps to speed up your metabolism by increasing the number of calories and fat you burn. Research done by the University of Wyoming found that capsaicin stimulates the body to create heat via a process called thermogenesis. Thermogenesis is a process in which the body turns calories into heat to use for fuel. It does this by activating receptors to start the process of burning energy. Receptors are found in brown and white fat cells. The white fat cells absorb calories and store them as fats (usually visible in pot bellies, wobbly thighs and love handles). These are known as “bad” fats.
Celery
Celery is one of those foods that seems to get a bad reputation. However, it really shouldn't. Celery is a perfect food for dieters because it is relatively low in calories. Not only that but celery is a thermo-genic food. It helps to boost your body's metabolic rate, which consequently helps you to lose weight fast. Celery also contains high levels of calcium.
Greek Yogurt
Greek-style yoghurt is one of the best foods to eat if you are trying to boost your metabolism and lose weight. Yogurt contains high levels of protein and calcium. It gives the body high amount of energy and helps in the building a lean muscle mass. Greek yogurt has live cultures that help to regulate the digestive track by contributing microflora.
