Sensa- Sensa Quench pre/post op

Does anyone know if Sensa pre/post op is okay.  I have been drinking Sensa Quench.  here is some info on it:  I need to look at the actual box for the full nutritional info. 

 

Ingredients
Vitamin A 5000 IU, vitamin C 60 mg, Vitamin D 400 IU, Vitamin B6 2 mg, Vitamin B12 6 mcg, maqui berry 1 mg, energy enhancing blend. Other ingredients: Malodextrin, citric acid, natural flavor, potassium citrate, silica, beta-carotene, acesulfame potassium, sucralose and beet color. May contain soy.

Directions
Add 1 packet to 12-16 fl. oz. of water and shake/stir. Drink 2 per day in between meals.

I haven't heard anything about this before, but sensa is the weight loss plan where you sprinkle your food with the powder right? I wouldn't combine rny with any other diet plan like this post op.

If shaking some "magic" powder on your "regular food" REALLY made you lose weight, then WLS would cease to exist.

Yet another fad diet preying on the overweight.
