Dr. Stephen Lawrence, associate clinical professor at the University of Warwick's medical school, believes four cups of coffee can boost metabolism by 3-11 percent. Higher metabolic rates make fat burning easier.
“Green tea includes the catechin epigallocatechin-3-gallate (ECGC), a potent antioxidant that reduces inflammation, prevents cell damage, and may assist weight loss,” explains nutritional therapist Lucy Miller.

One, published in The American Journal of Clinical Nutrition in 2010, indicated that trial participants who consumed the most dairy lost 12lb at the conclusion of the two-year study
while those who consumed the least lost 7lb (they had also been following either a low-fat, low-carb, or Mediterranean diet). Researchers conclude that higher dairy calcium intake and blood vitamin D are linked to greater diet-induced weight loss.
