Five-part "8" rule is this: 1. Get at least 8 hours of sleep per night (a good foundation for any healthy lifestyle change). 2. Do at least 8 minutes of moderate exercise per day (the funny thing is, once you do 8 minutes, you want to continue and do more; and if not, at least you got your heart pumping a little). 3. Eat 8 (total servings) fruits and/or vegetables each day (they fill you up so fast that there isn't as much room for the crap; plus as a woman with a serious sweet tooth, fruit is a diet blessing). 4. Never eat after 8 p.m. (good for your digestive system, better quality sleep, and of course, also a good diet habit). 5. Drink 8 glasses of water.
