WOO HOO!!! I lost 6 pounds in 23 days... BUT IS THAT HEALTHY?

I did not fully go on a diet.. I just didn't eat as much as I did before... but I do 1 hour of cardio with 1 hour of weight lifting... I have around 4 short meals/snacks... i think i feel healthier than ever...and i workout 7 days a week, i don't give myself a single day of rest.. but I was wondering if loosing 6.5 pounds in 23 days is healthy?
