Sounds like muscle mass to me. 4 straight days of work-out is probably not the best thing. Your muscle bulks up, so the weight appears as it if it's fat but it's muscle. Give your body/muscle time to rest after 2 maybe 3 days of work out max. Your poor muscles need a massage to relax and release and you should be back up and running in a day of good rest.

Good luck!

Start doing something small by replacing one meal a day with a protein shake. Some of them are mighty tasty. I'm having a slimfast 20g protein shake now and it's satisfying. 6 months is loads of time if you start super small now without stressing over it. Worse thing you can do is not do anything the first 4 months and try to crash the last two. Bad Idea.
