Hi guys. I've been trying to take my body more seriously since I've turned 17 this week, so I downloaded a few apps and bought a fit bit!

I've burned the correct amount of calories I need to achieve 10% body by September 16(so the app says) and I've been wondering if it mattered what I ate. I need to lift to burn more obviously, which is why I downloaded freelectics, but will I still have to drastically alter my diet? I don't think i should be eating food that I can't accurate calorie count.

Any tips?
