As many of you know, I embarked on a diet in December with the goal of getting to 160 pounds by June 30. I rocketed to the goal such that many of you expressed concern and I took note and slowed my efforts.

But, as my weight loss slowed and my exercise increased, I rationalized that I was still losing fat, but gaining muscle.

But, I'm an empirical person, and the raw math tells a scary story to me:

I started at 198 pounds with 26% body fat. So, I was 51.48lbs fat and 146.52 pounds muscle.

I'm not 170 ppounds with 20% body fat. So, now I'm 34 pounds fat and 135 pounds muscle.

So, I've lost 28 lbs, with 17.48 lbs of fat and 10.52 lbs of muscle. It is discouraging and scary to see that 1/3 of my loss was muscle!

Is is really possible to lose fat without losing muscle?
