Whatever field it is - earning money, becoming athletic, becoming a musician, becoming a good cook, becoming a good writer or public speaker - there are uncountably many people with a strong desire to succeed in that area and a subset of those that have dedicated their lifes to it.
Unless you're a world-class expert and one of the best in the world already, any insight you can come up with has been had by other people and if they're not doing it anymore it's usually for a good reason.
Even when the the "common sense" route is not optimal along whatever metric your measuring, there's probably something else you're not noticing: the classic dinner of potatoes/rice, cooked vegetables, and a piece of meat might not be the best in terms of health or nutrients or taste, but when you take into account things like ease of cooking, low cost, low mental effort, easy to make bigger portions, it very clearly becomes obvious why basically every civilization has traditional grain/potato-vegetable-meat type meals.
