Another win for your morning cup of joe: Caffeinated coffee keeps things moving through the digestive tract. Since staying regular is key to a tighter-looking tummy, drinking about 8 to 16 ounces of java at the same time every day can help you stay on schedule. Remember: Sugary drinks can lead to weight gain, so skip fancy flavorings and synthetic sweeteners containing sugar alcohols, which can cause bloating.
Close the Kitchen at Night. Establish a time when you will stop eating so you won't give in to the late-night munchies or mindless snacking while watching television. "Have a cup of tea, suck on a piece of hard candy or enjoy a small bowl of light ice cream or frozen yogurt if you want something sweet after dinner, but then brush your teeth so you will be less likely to eat or drink anything else," suggests Elaine Magee, MPH, RD, WebMD's "Recipe Doctor" and the author of Comfort Food Makeovers.
