The St. Luke’s Weight Loss Challenge is a program designed to help you achieve a healthy weight and an active lifestyle. We provide the content; you provide the motivation!

Two, six-month options offered throughout the year will be available to choose from, or, participants can re-enroll for the length of a year! Those who meet all requirements (weigh-ins and weight loss) will equally split the $10,000 prize money at the end of each six-month session.

How are the winners determined?

Winners are determined by the percent of body weight lost – NOT the number of pounds lost. 

Here’s how you figure it out: 

  • Take the number of pounds lost (ex. 12 lbs) from initial weigh-in
  • Divide by the STARTING WEIGHT (ex. 12 lbs divided by 200 = .06) 
  • Multiply by 100 (ex. .06 x 100 = 6%) 

How is prize money distributed?

NEW PARTICIPANTS who lose a minimum of 6% of their total body weight and KEEP IT OFF CASH participants whose final weight is the SAME or LOWER than their starting weight, will win an equal share of the $10,000 prize money to be split among the other eligible participants.

How often do I need to weigh in?

There are TWO weigh-ins during each six-month period of the program

  • Initial: October 24-October 28, 2022
    • NOTE - If you attended a final weigh-in for the 2021/2022 Challenge we can use it as your initial weight for the 2022,23 challenge (first six-month session only)
  • Final: April 24-28, 2023 (6% body weight lost by final weigh-in/roughly 1% loss each month)

In order to compete for prize money, you must attend EACH weigh-in at one of the official weigh-in sites.

Am I out of the Challenge if I miss a weigh-in or don't hit the weight loss goal?
You won’t be able to win a part of the prize money BUT you will still receive the weekly health tips, you can attend “Ask the Expert” webinars, participate in Carium challenges and win perseverance prizes.  
What should I wear when I weigh in?

Please wear a t-shirt and shorts/capris/sweats. 

Jeans/heavy clothing are discouraged. It will be marked on your weigh-in form and you will be expected to wear similar clothing at your final weigh-in.

How do I win prize money as a KEEP IT OFF CASH participant?

Those whose final weights are the SAME or LOWER than their starting weights will win an equal share of the $10,000 prize money to be split among the other eligible participants.

Do I have to pay taxes on the perseverance prizes?

Any valuation of the prize(s) received is based on available information provided to St. Luke's, and the value of any prize awarded may be reported for tax purposes as required by law. 

Each winner is solely responsible for reporting and paying any and all applicable taxes related to the prize. 

Notwithstanding the foregoing, any prize received by an employee of St. Luke's, with a value in excess of $25.00, will be reported to St. Luke's Payroll Department so appropriate taxes can be deducted and reporting can be completed.

If you are St. Luke's employee, the St. Luke's Weight Loss Challenge will report the value of any prizes awarded to you to the St. Luke's payroll department so appropriate taxes can be deducted on your behalf.  

If you are not a St. Luke's employee, it is your responsibility to report and pay any and all applicable taxes on any prizes awarded to you.

What if I want to re-enroll after participating in the six month program?

Did you meet your weight loss goal of 6%?

  • YES: You will then be designated as a Keep it Off Cash participant and your goal will be to maintain don’t gain. Your final weight must then be EQUAL to or LOWER than your final April weight
  • NO: You will not receive any allocation of prize money and can choose to register for the next available Weight Loss Challenge program.
