Try to fit as much exercise as possible into your day. Take the stairs instead of the elevator. Stand instead of sitting and if possible, walk instead of stand. Pacing can be very helpful. Fidgeting has been shown to help with weight loss, as well. Jiggle your foot, tap your toes and drum your fingers. It may not seem like much, but it adds up quickly!
If you want to control your weight, make sure that you are getting enough sleep. When you get enough sleep, the hormones that regulate your appetite are in balance. However, when you do not get enough sleep, these hormones are out of balance, causing you to overeat. Lack of sleep also slows down your metabolism, which will interfere with your weight loss.
