Lose weight faster with DietBet and your friends

May 28, 2013

DietBet (@dietbet) enables runners and other RunKeeper (@runkeeper) users to lose weight socially by challenging their friends to a fun weight loss competition. Below we discuss how DietBet uses the Health Graph API & platform (@healthgraphapi) to help motivate people and keep their weight loss journeys fun.

Bill Day: Please tell us about yourself and your work.

Adam McClean of DietBet

Adam McClean: I’ve been a product manager for almost eight years with a primary focus in e-commerce and consumer brands. I’m also training for a mini marathon later this year.

BD: What is the “elevator pitch” for why someone should use DietBet?

AM: DietBet is the best way to jumpstart your weight loss and access the support necessary for success. It’s a great mix of behavioral economics (loss aversion and financial incentives), community, and accountability. Players put money on the line and commit to losing 4% of their starting weight in 4 weeks. During the game players make friends, talk smack, and track their progress as they approach their goal. Everyone who reaches the 4% goal ends up splitting the pot — and making some extra money!

BD: How did you get started using the Health Graph API?

AM: I’ve been using RunKeeper and saving my personal data to the Health Graph for a long time. After I participated in my first DietBet, it was clear the two should integrate.

BD: How will the Health Graph platform benefit your business?

AM: Running and weight loss have a symbiotic relationship: Losing weight helps you improve your running time and running helps you burn calories and lose weight. Players who connect with RunKeeper will be able to send weight updates and running activities directly into their DietBet game. Also, any weight updates made on DietBet will be saved back to the player’s Health Graph account.

BD: Which portions of the Health Graph API do you use, and why?

AM: Since DietBet players are required to submit their weight in order to play the game, we wanted to allow them to do this from both DietBet and RunKeeper. We are using Weight Measurements to get/post all of the weight data. We are also grabbing running details from Fitness Activities, so other players can see the hard work being done to help a player make their 4% goal.

BD: What do you like about the Health Graph API?

AM: We love the simple approach to tracking changes using Root Resource and Change Log. This lowers the overhead on our end and lets us post activities and weight updates within minutes.

BD: If you could request any new feature from the Health Graph platform, what would it be? How would you use it?

AM: Most weight data is inputted manually using the honor code. Because we have a team of referees and a photo-based verification solution, we’d like to be able to indicate when weight entries are “verified” vs “manual” the same way you can specify a “tracked” vs “manual” fitness entry.

BD: Can you share any future plans for DietBet? What’s coming next that people will be excited about?

AM: We’re hoping to expand beyond the current game (4% in 4 weeks) and allow users to play games with longer timelines and larger weight loss goals. We also want to reward players for maintaining their weight or establishing healthy habits.

BD: Is there anything else we should know about you or DietBet?

AM: Organize a game today and use promo code HEALTHGRAPH. If you get 8+ other players into the game, we’ll refund your bet!
