Put clothes in the washer. Empty the dishwasher. Increase your activity in small steps. Use the stairs instead of the elevator. Park your car further away from your destination.
Little changes add up to big rewards over time.
Keep a food diary. Note what you ate, when you ate it, with whom, and what your mood was at the time. Analyze your diary to help you find patterns. If you don't learn what triggers overeating, you are just snipping the weeds, but not tearing out the roots. Don't eliminate your favorite foods.
