My Fitness Pal

I received an activity tracking band as a gift.  This bracelet can be connected to "My Fitness Pal".  I'm trying to adjust the goals to accommodate a healthy diet for a gastric bypass patient.

It's been over 10 years since I had the Ruen-Y.  I slipped on ice on Jan. 3 which resulted in a broken wrist and leg.  I've gained 14.5 lbs. from the inactivity and a diet high in carbs served at the rehab.

Can anyone share some wisdom on a % breakdown of a healthy bariatric diet?

Thanks!
