I'm not sure how serious the OP is, but it's crazy how little is known about optimal nutrition. Most of these new (or at least newly trending) food plans rely on a small number of studies that are contradicted by a bunch of other studies. As one example, people who support the keto diet will talk about it like the science it relies on is a simple fact. This is not true and many very smart people do not agree with much of what keto says about the insulin process and the role it plays in gaining/losing weight.
Given the lack of scientific agreement, the logical approach, barring diets based on ethical or religious concerns, is a moderate one- a balanced diet that includes some amount of meat, carbs, fruit/vegetables.
