metabolic rate and Olympic weightlifting

In the last week I've lost 1.6 pounds. That's a little quicker than i had originally planned, but my strength doesn't seem to be affected at all. Last week i squated 301 pounds 6 times.  And today i tied a training PR snatch of 81k. In the last 3 weeks I've lost 1.75 inches around my waist. I've accomplished all that while eating 3,250 calories a day plus eating any calories burned from working out.  That means my metabolic rate is still hovering at around 4,000 calories a day. The life & metabolism of an Olympic weightlifter is great!
