When you've finally reached your goal and size, it can be tempting to throw your scale at the garbage and never look at it again. That scale, however, is essential to keeping excess body mass off once you've gone through all the hard work to lose it. While maintaining your weight, you need to be aware of how much you actually weigh. Pick a day of the week and weigh yourself every morning on that day. Write it down. This way, you're aware if you've gained any back and can curb it before it snowballs into anything serious.
Just 10 extra pounds add 40 pounds of pressure on your knees and other lower body joints. That can wear them out quicker. Extra fat can also cause inflammation -- when chemicals in your body damage your own tissues over time, including your joints. Losing even a little weight can ease these effects. If you keep it off, you’re much less likely to get arthritis later in life.
