New research indicates sipping green tea can help with weight loss. Green tea has zero calories and includes catechins, which when combined with caffeine actually speeds up your metabolism. A faster metabolism increases then number of calories you burn from fat, according to a professor of nutrition at Tufts University. Sipping two or more cups of green tea per day that has been steeped for at least three minutes is the most effective drink to help with weight loss and promote wellness, since the longer the green tea steeps the more catechins you will consume. Enjoy!
