Context I have lost weight a number of times in my life. Each time the success was led by some form of data analysis and technology. In 1993 it was using a simple Excel spreadsheet and weight loss graphs. In 2010 it was through use of the Withings WiFI Body Scale and a blog. Now, I will be mining a larger variety of data sources and variables. But why stop with me? In today's world of open access and big data, I am hoping my data can serve as an interesting analysis source to a lot of data scientists. Who knows what interesting insights the story of my nutrition data may supply. My Pledge To make this data set useful, others will need a commitment I have to maintaining the data. Therefore, I pledge that, for no less than the entire year of 2019 (it could be longer) I will... - Record data daily. (Although I can not guarantee that every data point will be available every day.) - Add additional data sources if available, collectible and requested. - Upload additional data points to Kaggle no less than twice per week. (This data set will go through a lot of new versions.) - If new variables are added to a file, they will only be added at the end of each record. This is to assure a degree of backward compatibility of data files from version to version. Content The `weight.xxx` files contain daily recorded health and nutrition data from a variety of sources. - The Nokia Healthmate app (fed by Withings' Body Cardio scale); - The Apple Health app (fed by Apple Watch and Motiv ring); - The Motive ring app (fed by the Motive ring); - The Under Armour MyFitnessPal app. The MyFitnessPal app records self-reported daily food intake. To make this data as accurate as possible, I weight and measure my food to the extent possible and use barcoded look-ups whenever possible. The `measurements.xxx` files contain measurements of multiple body points recorded on no less than a monthly basis. The `bp.xxx` files will contain blood pressure measurements and be uploaded on no less than a quarterly basis. Acknowledgements To gather this data, I owe thanks to the following quantified-self devices: - Apple's Apple Watch - Apple's Health App - Motiv's Motiv App - Motiv's Motiv Ring - Nokia's Healthmate App - Under Armour's MyMitnessPal App - Withings' Body Cardio Scale - Withings' BPM Blood Pressure Cuff Inspiration There are so many theories about what is the source of weight loss. Data points from one person will hardly answer that question empirically, but it could be a start of some eye opening analyses - and perhaps an inspiration to others to record and make public more of their own data as well.
