Engineers are awesome

Why do I love engineers?  Because they do things like this.  The Hacker's Diet is my weight management bible.  I'm not saying it will work for everyone, and I'm not proselytizing.  However, I will sing its praises because it works for me and because it has equations for calculating daily trend.  Unless you are gaining weight at a rate of multiple pounds per day, your weight will fluctuate up and down from day to day.  What you care about is the trend of your weight.  Does it go up or down or stay the same?  Using trend equations and a handy google spreadsheet, I can see the general direction of my weight.  And it makes me feel better.  Check it out:

The blue line is my weight from daily readings, and the red line is the trend line.  Suddenly those fluctuations don't matter nearly so much, because as long as they're below the trend line, they're still pulling it down.  Hooray!
