Your average weight change over these weeks is -1.4 lbs/week but it appears to be somewhat steeper in the first 10 weeks. Pretty respectable, I think.
Unfortunately, for some reason Excel won't yet let me expand the vertical axis so I can see temporary ups and downs. Sometimes I get it to work, sometimes I don't. And the Apple people have stopped giving me free online help and now want me to buy the help.
By comparison, my average over 40 days is -0.99 lb/week but over the last five days I've somehow averaged -1.05 lbs/day
. Regardless, I've felt over the entire 40 days that I am almost starving myself.
BTW, because of food transit time, less than a three day average does not mean much and because of weekly variations, seven days is a good minimum. To avoid systematic errors from weekly variations, taking a reading every 6 or 8 days is probably a good idea.
Got the graph to work, my mistake, this time I wrote down the steps to reformat an axis.
Your change from week 17 and on is more or less a straight line at -1.1 lbs/week and so for next few weeks you can expect pretty much the same.
BTW, a straight line doesn't fit your data too well - in the first 6 weeks you lost 2.9 lbs/week - it's concave upward so it's an exponential or reciprocal curve. But my Excel doesn't do sophisticated curve fitting so I use the straight line method and your last few weeks are following a pretty good straight line.
There are probably pdf documents on the Web where researchers have come up with formulas for the weight loss over time for most people.
Speaking of which, do you have data for the first 20 days or so, and the last 20 days? The daily variation might provide a clue as to whether you changed your habits or your body has adapted to the weight loss routine.
With your data and mine we have two sets of samples to compare with others on this forum. A good start, and I can always use practice in interpreting graphs and data.
Been to Germany & England, never to France except for the Colmar region. Got to do it soon!
