Protein shake virgin! Help!

Kai_Milla1

Well, I've hit a plateau in my weight loss and on top of that I am not gaining muscle like I thought I would be....so I calculated how much protein I should have a day and I'm getting about 1/3 of it (if that calculation is right). Im 20, 128 pounds, 21.6 BMI, 1200 cal diet and the calculator I used said I should have about 74g of protein.

SO my questions are is that the right amount? Is it a good idea for me to start drinking these post workout- I've seen yes and I've also seen its bad for weight loss so I'm confused, but I have to get all my protein somehow! Plus, in my earlier post I was told in all responses to eat more and that I wasn't consuming enough calories so this should help with the cals too...right?

Here's some of the nutrition facts on the kind I bought, It is "Pure Protein whey protein"
160 cal per scoop (which is a serving size)
3g fat
190mg sodium
7g carbs
2g sugar
25g protein
20% calcium

Theres also 8 essential amino acids and 8 non essential also......so is this a good idea to start doing post workout mon-friday?
