When one remembers that 3500 calories = 1 pound of weight, it is relatively easy to understand how to lose weight. Decrease your caloric intake or increase your caloric expenditure by 500 calories a day and you will lose 1 pound a week, safely. Now comes the hard part -- deciding how to increase expenditure or decrease intake. Start with the advice given above -- eat healthy stuff. Increase your activity level -- take stairs rather than elevators. Ride a bike rather than driving short distances. Park farther away from where you work and where you shop. Good luck and take it easy in your exercise. Make sure you are healthy enough to do the exercise you want to do.
