"Water promotes weight loss. Most dieters do not drink enough water. To metabolize 1 gram of carbohydrate, for example, your body needs 3 grams of fluid. So drinking enough water can help keep your carbs from being stored as fat. [...] after two glasses of water, your system 'shifts into high gear and starts burning fat'. And German researchers found that people who consume two 240ml (8 fl. oz) glasses of water increased their rate of calorie burning by 30 er cent about 40 minutes later, and it stayed elevated for more than an hour. "
Exercise is very important to incorporate into your weight control regime. "But, exercise cannot compare to the exercise of good judgement with your food choices! [...] exercise gives you a crutial edge. That edge, however, might not be what people think it is. Exercises's greatest contributuin to a success at weight control - because it gives focus and structure. It encourages the right behaviors for dieters... not just the calorie burn."

P.S. In case you are curious about this book - you can read an excerpt at Amazon.com . I am very impressed with his advice, not just for losing weight but more importantly the strategies he offers for maintenance.
