So I unexpectedly went up 20 pounds in two months. I eat 1200 a day and record everything I eat. I eat a balanced amount of fruit, veggies, protein, etc. For exercise I run 5 miles a day, do weights and ab work, callanetics and yoga, and I change up my routines. I got a blood test and everything came out fine.

Does anyone know why this is and why I can't get my muscle and body shape back?? I just have this huge amount of flab coming up over my jeans and i've never had that!
