It is tempting! But since our bodies fluctuate on a daily basis depending on time of day, hydration level, sodium intake, and time of month (for women) I would try to stick to once a week. As hard as that may be, try to pay more attention to how your clothing fits, your hunger/fullness signals, portion sizes, and your energy level. It is so easy to get obsessed by jumping on the scale every morning and letting that number rule your day. Been there, done that!
When you do hop on, make sure it is at the same time of day, with the same clothing, and the same amount of time after having consumed food or liquids. First thing in the am is a good time to keep consistent. Try not to get hung up on the number, but rather how you are feeling: increased energy, able to climb stairs without huffing and puffing, effortlessly carrying bags of groceries up 3 flights of stairs. I know, it is easier said then done, but at least try! If the number goes up and your cloths are getting tight, buckle down and increase your activity level – walk/run an extra mile for the next week, or go out dancing or bowling instead of sitting through the latest theater release, get off the bus 3 stops early and walk to your destination, or take the dog for an extra walk. And eat a little less – leave a bite or two of every meal and snack. Remember moderation, not deprivation!
