Sugar-free liquid diet for diabetics?

[Guest guest]

We're now requiring a 2-week low-kcal liquid diet for our pre-ops. We give them

the option of OPTIFAST, Celebrate's Chike, or Bariatric Advantage's HP meal

replacement. Has anyone seen a problem using the sugar-free/1 g sugar MRs

(Bariatric Advantage or Chike) in diabetic patients?

I prefer they use OPTIFAST to keep a steady cho/protein intake, but the BA costs

less and we serve a pretty financially constrained community.

Thanks!
