Woah, you put ice cream in your whey? I can guarantee you will get fat like that. If you must , mix it with some skim milk.
Can you get fat on protein shakes alone without diet, sure you can if your calorie intake is above and beyond your maintenance level.
Theres a ton of sugar in ice cream.
I guess the question I want to ask is, why are you taking protein if your not exercising? Its a waste of money.
