Need some help in interpreting my graph. For those of you who make graphs on the spreadsheets, here are the datapoints which you can paste into two columns.

A Web calculator shows that I need 2120 calories per day to maintain my weight.

Fat weighs 1 lb per 3600 calories so 0.6 lb is 2100 calories.

The latest slope on the graph shows -4 lbs in 7 days so -0.6 lb/day which is almost what I'd expect if I were fasting.

With this slope I should cross through 150 lbs in 27 days, give or take.

So I'm burning 2100 calories more than I'm taking in? Does this sound right?

Graphs convey a lot of information so I'm open to any opinions on the meanings of this bumpy line.
