It's interesting that you HDL is down.

LDL in some folks goes up, some folks stays the same and others goes down.

One theory here is that as you've begun to mobilize fat for fuel that there's a lot of "good LDL" (small particle) that's free in your system to do it's job of providing energy or whatever.

There's a more complete blood test called - can't remember the name now - but it differentiates the different "types" to a finer degree.

Lot's of discussion on this board about it. you'll get some ideas. If you can work with your physician you might want to re-check when you get out of "weight-loss mode" and into what might be called "maintenance" - see where you numbers land then.

Relax and continue your approach is my recommendation, but I'm not a doctor
