I certainly don't think you gained that kind of bodyfat that quick. I think the extra carbs and glycogen is throwing you off because of any possible fluid fluctuation of water you're holding. Jumping a coule hundred calories isn't going to make a drastic change that quick on composition. Sodium and potassium could also be playing a role here as well.
Thanks RickRock! I didn't really think it would cause that much of a change, but after people here hinted at this, I did more research and sure enough, that is most likely the case...which is throwing off the calipers. I'm definitely consuming more water and pissing alot, but I'm sure the increase in carbs is increasing in my cells accordingly as well. This was a good learning and I appreciate your response.
