 Motivating Weight Loss Plan

  1. Combat portion distortion.  Make sure you're eating the right amount and adjust your caloric intake to what works for you, not too few calories and not too many. This is necessary to rev up your metabolism.
  2. Visualize the finish line. Create a photo timeline of yourself. Take a new photo of yourself every week. Celebrating your small successes will keep you on the path toward your greater goal.
  3. Automate your workouts. Cut out the excuses by getting workouts off your to-do list. Exercise first thing every morning.
  4. Build community around your weight-loss plan. Friends and a support network are a necessary part of your success.
