If you haven't read this, you absolutely must.  It is the best explanation
of overweight and related problems I've ever come across.  It's fairly
technical, but if it gets to be too heavy to slog through, sift it for
words you recognize.  It's too important to ignore, and will answer tons of
questions.  Go to lowcarb.org and click on Adiposity 101.  I downloaded it
to print because it's something I'll be wanting to refer back to
frequently.  It is 76 pages long, so be prepared to spend some time on it,
but don't miss it.
