Should I be taking a Whey Protein/Will it help me lose weight

The only thing protein shakes are useful for is to supplement your protein intake if you're not getting enough protein in your diet from other foods. That's it. There's no weight loss magic to them unless they somehow help you stick to your calorie goal (which is how the weight loss happens). Adequate protein intake is good for the body for several reasons, but if you're getting enough through regular food, there's no need to supplement with protein shakes.
