Limit yourself to two mug-sized cups of coffee a day. If you are drinking too much, cut down gradually and not at once to avoid withdrawal symptoms. If you are drinking six cups a day, first cut down to five, then to four. Choose a smaller cup size to reduce your intake without cutting the number of trips you make to the coffee shop. Mix your coffee so it is half decaffeinated and half regular. Opt for low-fat sweeteners rather than sugar to cut down on calories. Avoid ordering coffees with high cream, sugar and chocolate content. In general, the more elaborate the coffee, the higher the calorie count will be. Think about cost. Buying four cups of coffee a day at $20 a cup will set you back $400 every working week - or about $20,000 over the course of a year.
