Direct answer
Which protein shake should you use and when?
According to Dr. Paul Arciero, product selection is preference-oriented, with nuance around when an option is ideal. The interview discusses different categories for a complete meal, workout or on-the-go use, hot-weather hydration and nighttime use; a coach can help connect those categories to a person's goals.

What is the difference between a complete-meal shake and a protein supplement?
The nutrition coaches distinguish a complete-meal option from products used primarily for protein support or specific use cases. Rather than treating every shake as interchangeable, the discussion connects product category, timing and a person's goals.
Direct answer
Why does product selection depend on a person's goals?
Dr. Paul says the options are preference-oriented but have nuances about when they are ideal. The nutrition coaches therefore recommend a conversation before choosing a product, especially when someone is trying to fit nutrition into training, travel, hydration or nighttime routines.
