Source: I weighed myself every day, logged into Excel

Tool: Excel into Power BI for visualizations

I used a 3-day rolling average as my primary metric to smooth out the high variability day to day. While I hit my goal a few times on a single day, I only considered my goal met when the 3 day rolling number hit the line.

Starting a weight loss journey around the holidays is tough, but not impossible. You can see some of the big upswings when viewing at the week level are all around the big holidays and weekends where we had holiday "stuff" going on (eating and drinking a lot). Week 11 started the Monday after Christmas, the only WoW increase in weight up until that point.

Another interesting, but maybe not surprising, datapoint is my average by day. Mondays are always my heaviest (coming off of the weekend) and Thursdays are always my lightest (coming off Mon-Wed of healthy eating and exercise). By this logic Fridays should be my lightest, but about half the time I give up by Thursday night and have some wings and beer.
