Lose weight faster with DietBet and your friends

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!

Health Hack Day recap

The Stockholm Health Hack Day (@healthhackday) was a great success! Thanks to everyone who attended, spoke, organized, or otherwise assisted in the event.

Speaking of the organizers, they did a wonderful job arranging for video recording and streaming of many of the panel, presentation, and discussion portions of the hackathon. You can check out all the videos here, but I want to call your attention to these three Health Graph (@healthgraphapi) related videos in particular.

First, Oskar Henrikson interviewed me about RunKeeper and our vision for the Health Graph before the event:

Later that day I delivered a high level overview presentation on the Health Graph platform:

And we closed out the first day of content with a panel discussion about health technologies and consumer grade services:

The only session of mine that didn’t get video recorded was my more technical Health Graph workshop from the second day of the event. But fear not, slides are available!

Team presentations from the demo day were also recorded. One of the very neat things for me is that the top three teams used or have plans to use the Health Graph. You can watch the awards presentation to those teams here:

You can watch the demos from these and all the other teams by clicking here.

I’d love to hear your feedback on the event if you attended in person, or on the materials above if you participated online.

Health Hack Day howto

While this post is targeted at attendees of the 18-20 May 2012 Health Hack Day events in Stockholm, even if you’re not attending you still might find some useful Health Graph information and development tips. If you aren’t able to attend in person, you can also watch the livestream online.

Welcome Health Hack Day attendees and hackers!

You’re in for a great weekend of hacking, networking, and fun. And who knows, maybe even a prize at the end!

This post will walk you through the key information and procedures you need to use the Health Graph during the hackathon.

First up, here’s a copy of our Health Graph programming primer to get you going (click through the presentation and note that links are live):

More details on some key points:

You can access more technical details on the RESTful Health Graph API by clicking here.

All Health Graph partners are required to follow the Health Graph API Policies.

When you’re ready to get started building a Health Graph API application, visit the RunKeeper Partner page and click “Connect To Our API“. From there you can fill out the form to register your new Health Graph integrated app, service, or device.

Click here to learn about authorization removal callbacks before providing your callback URL on the form. If you will be reading data out of the Health Graph for accounts other than your own app registering account, you should also request Read permission on the form, being sure you give a detailed explanation of what you will do with that data once you’ve accessed it. Likewise, if you would like to ask users for permission to retain their Health Graph data across deauthorizations, please request this permission on the form.

Note: Please include the official event hashtag, #hhd12, in your new application description and permission justification so we can address your request as quickly as possible.

Need some inspiration to get your developer juices flowing? Check out some of the applications built and deployed using the Health Graph API, available from the RunKeeper Apps page (click here). You can also access an archive of third party libraries, wrappers, and bindings which might make your Health Graph API-based development easier by clicking here. And there’s more information on how app and library partners are taking advantage of the Health Graph via our Health Graph partner profiles series on the blog.

When you encounter issues, you can ask questions and join in the developer conversation by visiting the Health Graph discussion group. You can also reach our team on Twitter, Facebook, and Google+.
