Allow the road to auto-adjust down to current weight: "Don't gain, maybe lose" goal
The following is from a user who wants to remain anonymous [note that i think you can also post anonymously by just coming here in a fresh browser session]:
I would like to never weigh more than I do today. I also wouldn't mind losing a bit of weight, but I would like it to happen naturally over time without any strict dieting or goal-setting, and while learning to eat for maintenance. Sometimes I do lose a little without thinking much about it - that's the ideal situation. However, when that happens, I would like the yellow brick road to adjust down automatically, so that I get a warning if my weight starts increasing again. This way, I'll be a bit leaner every month.
One way to do this would be if you allow the middle of the yellow brick road to always adjust down to a little bit above the weighted average (e.g. 1 standard deviation). The road should always move down automatically, but never up.
This would be a great help for effortless, long term sustainable weight loss. In particular, it works great with a withings scale, because you lose weight slowly while never having to think about your weight - unless it is increasing.
