Why?

It is just as easy to loose the weight AND Gain some "proper" Muscle if you take the right approach to it, Why put in all the effort just to have to start it again when he wants some muscle mass.

Keep it up as your doing but if i was you i would gert on a "proper" Diet and hits the weights aswell, as if done correctly they will also ADD to weight loss.

Losing the weight and people noticing it and giving you compliments will give you the motivation you need.

Just remember Rome wasnt built it a day and it all takes time.
