Starting a new challenge

I have committed to the 90 day-Body By Vi challenge. After a lot of research I thought that I would use this as a tool to get past the plateau I have reached on my weight loss journey. During this challenge I will still eat healthy and workout, this not an excuse to do whatever I want. My hope is to lose 30 lbs just in time for my 26th birthday that is coming up in January.
My starting measurements are as follows:
Chest: 48"
Waist: 60"
Hips: 54"
Weight: 304lbs
These pictures represent me at the start of this 90 days.
