Exercising and healthy eating are the key to losing weight.  However, there are other factors that could optimize how to lose weight fast.  Some of these examples include drinking plenty of water, at least 8 glasses a day, because dehydration could lead to a lower metabolism which will lead to the burning of fewer calories.  Another example is snacking on nuts, because they have high protein content. The body requires more energy to breakdown protein, which ultimately leads to more calorie loss.  In addition, breakfast is the most important meal of the day, yet most people skip breakfast thinking they can lose weight this way. On the contrary, a good healthy breakfast can keep you from feeling hungry for many hours, which can keep you from making unhealthy choices later.  Avoid fast food at all costs. More than two meals per week can lead to a gain of 10 pounds. Spicy food, iced beverages, coffee in moderation, and even green tea can help boost your metabolism, though for short periods.
