I have always been in fairly good shape, but a couple months ago I decided to make it a priority to work out and eat healthfully. Since then, I have been working out 4-6 days a week and trying to eat better. I have been doing great, seeing steady improvement, and overall feeling really good! But in the last week or so, I gained a lot of fat around my belly...I can't think of anything I've done differently that would spark this. Any ideas? It's really discouraging...especially since I just got a cold and haven't had the energy to go work out for the last few days.
