But no matter how amazing his initial transformation was.
The real question was... was he able to keep the weight off?
Because a lot of people lose weight quickly, but then quickly gain back.
Luckily, I've kept in touch with Michael and not only has he kept the weight off.
In fact, today he's fitter than ever before.
He went from barely able to walk for 5 minutes to running an 11 mile obstacle course.
