We would not recommend using water to prepare the Slim-Fast powdered shake mix.   Preparing the shake with water will not provide sufficient calories or nutrients to equal what you should take in for a meal.  The powder alone without milk will be lacking in vital nutrients including, protein and calcium.  Mixed with water the shake will be equal to a snack, not a meal.

Also, we would not recommend that you go too low with your calories and we never recommend a diet with fewer than 1200 calories per day.  It is best to follow the calorie level that is right for you for the best weight loss results.

You can feel free to prepare the shake mix with calcium fortified rice or soy milk.

Sincerely,

Amy Hehn, RD, LDN

Also, I just don't like using cow's milk in general... I'd rather use rice milk.

Hello,

I was wondering instead of using skim, fat-free milk to mix the powder with, could I just use water? Skim milk still has about 90 calories in it and I'm trying cut as many as possible.

I know they aren't fat calories, but I don't care.
