Goal Weight

Enter your goal weight and when you would like to reach it.

You can enter a number of days OR choose a specific date using the calendar.

Physical Activity Changes

Click the "Calculate" button to show how you will change your physical activity.

Changing your physical activity can help you reach and maintain your goal weight.

The physical activity changes you make will impact how many calories you need to eat to reach your goal and maintain it after you have reached it.

If you don’t want to change your physical activity, click the “Next Step” button to skip this step.

Results

The "reach your goal" and "maintain your goal" calories displayed assumes you will continue the physical activity changes you previously entered in step 3.

Do your results seem too high? People often underestimate how much they eat and the Body Weight Planner values are accurate for most people. If your metabolism is abnormally low or you are very sedentary then Body Weight Planner values will be too high.

Tips for Eating Healthy

Tips for Getting or Staying Active

  • You don’t need to be active for long periods to get the recommended amount of regular physical activity. Find ways to build short bursts of physical activity into your day, like taking a 10-minute walking break at work or using the stairs instead of an escalator or elevator.
