Hi Kristen.

to the beach!
I didn't really know how to reply to your post but wanted you to feel welcome. SBD is a very healthy way of eating, no matter how much you have to lose so whether it's 10 or 100 pounds, it's not a quick fix but a healthy lifestyle.
I would wait until after you get passed the first 5 or so days on Ph 1 before changing up the exercise. Detox makes you feel draggish, but each person is different. Zumba is a good way to exercise.
Good luck and let us know if you need anything. Post often!
