“Should I increase my carbs to help with my performance”
“What do you think of the keto diet”
“I’m eating 190g of protein per day, is that too much”
In every example listed above the thing that’s missing is context. Without enough context I have no way of knowing what any of these people should do. It’s like going to the mechanic and saying “My car isn’t working, should I change the spark plug”? Without a proper needs analysis the mechanic will have no way of knowing what the issue is, and therefore any suggestion they make will be purely based on speculation.
