One Week Metrics

After what looks like a two day adjustment period during which my weight dropped about 1 lb.,  by the morning of the third day, any weight loss exprienced has been erased and we see a subsequent gain in weight, possibly due to water retention as well as digestive tract contents?  The morning after not having eaten potatoes, we see the most significant drop in weight.  It will be interesting to see the net effect of substituting rice for the potatoes.

Oone week of eating significantly below my maintenance level of calories, and it looks like I’ve experienced some net fat loss, about 3.3 lbs (scroll over the graph points to see the actual value recorded).  This is respectable, but is this the result of the magical satiating powers of potatoes?  I doubt it.  I expect any dietary intervention that I could sustain at this level of calories ( 1500 kcal. ) for a week would have produced equivalent results.  Of course, when you take a look at the weight graph above, you will note that my total weight has only changed about 2.2 lbs., which would suggest that I lost fat and gained non-fat mass … all on 1500 kcal. a day.  This is very unlikely.  It is quite possible that this is the result of basic variance ( error ) in measurement, or the model being used is being confounded by water retention changes which are interpreted as changes in non-fat mass.

I don’t have the data on hand to post right now, but this evening, I promise a graph of the changes in subcutaneous fat as measured ultrasonically.  That could be quite interesting.
