If all you have is two weeks to lose weight, you’re going to have to be very strict with this rule. Luckily you can still drink any water-based drink such as coffee and tea, so it’s not all bad. I usually have a huge glass of ice cold water plus one or two large cups of coffee in the morning to kick start my day. I often use cinnamon to flavour my coffee – it’s a great tip for those of you that really enjoyed adding milk.
Green tea isn't known only for its cancer-fighting benefits: It may help boost your metabolism, too. People who took green-tea extract three times a day saw their metabolic rate increase by about 4 percent, according to a study published in the American Journal of Clinical Nutrition. (Translation: You could burn an extra 60 calories a day, which equals about six pounds a year!) It may be because green tea contains catechins, which increase levels of the metabolism-speeding brain chemical norepinephrine, says Joy Bauer, a New York City nutritionist and author of Cooking with Joy.
