The majority of personal trainers and nutritionists don't have much of a real scientific background, and unfortunately most people who do have the background don't pursue nutrition/health.
I'd say the majority of "BRO-advice" out there to ensure a massive insulin spike post-workout is quite overkill for most people. For one, repeating this type of regimen may eventually engender insulin insensitivity and perhaps even type 2 diabetes in those susceptible (there are quite a few diabetic bodybuilders out there, for reference). Secondly, most people can get an adequate insulin response from whey protein alone (that's right... without ANY carbs).
I'd still use SOME carbs, but almost anyone can get great results without excessive amounts. I use protein and perhaps a small amount of fruit... then a meal of course.
Having some circulating fats in your system during a workout seems to also allow your body to burn more fat overall.
