1. The Scale is the First Place
The scale should be your first indicator that your weight is getting out of hand. While there is no exact number you should stay at your entire life, the scale will be able to give you a reasonable estimate of where you are in your body weight. If you have not been to the gym and you recently have gained five pounds, this could be a sign that you are gaining weight. Also, your doctor can give you a good understanding of where you should be at with your weight, so if you go above that, then you probably have too much around the waist.
