As a recovering connoisseur of calories, I can say I was tired. I hated trying to find clothes to wear for things. I didn't realize it at the time, but even tying my shoes was harder than it should've been. 

After getting a trainer and traking my macros, I dropped about 40 lbs in 6 months. It was night and day. The old saying is true... nothing tastes better than thin feels.
