Protein supplements – Necessary for everyone? I wouldn't make that broad of a generalization. In fact in an ideal world they might not be necessary at all, as we would all have time to prepare for, cook and eat our meals 3 or more times a day, every day. However not many of us live in that kind of world. Protein shakes make it easier to get in the amount we need on a daily basis. Whole food would be the best first option, generally speaking. That being said, the convenience and versatility is hard to ignore.

As far as being goal related, I personally wouldn't differentiate between the ones you mentioned when it comes to having adequate protein intake. Building lean muscle tissue is related to almost every appearance and performance related goal. Protein supports building and preserving muscle, boosting metabolic rate, and losing bodyfat. Using a protein supplement around training times helps provide adequate "mortar" for laying the "bricks"; i.e. lean muscle.

Make sense?

Continuing on with this topic, here's my question: does everyone need to do some type of protein shake/supplement in order to see results OR can regular food intake of protein be sufficient for some/all? Does it depend on the goal/objective (ie: look muscular, tone, lose weight, etc)?

Thank you!
