I feel the same way - once I started exercising, I stopped being strict w/ the food plan. I had lost 35 lbs before starting to exercise and since I started 2 mos ago, I've lost a few lbs - like 4 lbs in 2 mos
They also put me on a higher food plan, but like you - I'm completely unfocused on staying on plan.
So I'm going to try my best - starting w/ take-off tomorrow, to get back on track AND keep exercising.
