Two years after losing weight, most dieters weigh more than they did before they started dieting. For those that are still working towards our weight goal, lets back up to where you are now. Losing weight should not be your only goal. You should be adding in goals for permanently changing your diet and not just for the purposes of weight loss. Goals for exercising since your body needs exercise to shed calories and keep your mind, muscles and lungs strong.
Without changing the way you live while working to lose weight, you will gain it back again. If you set a goal to lose weight and then stop your routine for that birthday cake, holiday table, or pot luck, (you will be surprised when you realize how many of them there are) you run the risk of gaining back everything you lost and more besides. You will not need to try as hard once the weight is shed since you are no longer trying to lose weight, but you will need to keep moving and sweating as well as eating what your body can safely use for fuel.
Drink water. 5-10 pounds of the weight you carry is water weight. If you are not dinking enough your body thinks it is in a drought and starts retaining water for survival. Why carry around the extra body water when there is so much to be had around you? By the time you think you are thirsty your body is already significantly depleted. The next time you drink it is going to retain what it can until the next source is obtained. Drinking more regularly may send you to the bathroom more often, but that is only because you are finally giving your body the chance to use the water as it was intended. For flushing your system and refreshing what is outdated.
