If You're Serious About Losing Weight, Follow These 5 Rules

Losing weight is about simple math: you have to burn or cut out 500 calories a day to lose one pound in a week. If you burn 250 calories on a morning run, you'll need to cut out 250 calories from your diet that day. Don't get in the mindset that a workout gives you a free pass to splurge, because you'll end up taking in more calories than you burned, which will result in weight gain instead of weight loss.
