@minagica OP is corect that the word diet is not restricted to weight loss, and also as to the defintion of the noun. On the other hand, the definition of the Verb, 'to diet', does (at least ot hte best of my knowledge) exclusively refer to attempts at weight loss. At least in modern usage.

@zukodude487987 we are designed to consume carbs, and there is a minimum we should be having... but there's also a maximum and these days it is fairly routinely exceeded. Said maximum is tied to amount and type of exertion, mind you. And the type of carbs in question is also relevant: Sugars are actually useful and necessary to brian function, but humans are wired up in ways that work great when your primary sugar source is Fruit, not so great when it's 'additives in the vast majority of foods in your diet', as the latter results in an excess of sugars in general, and an imbalance of sugar types, when treated (as the human brain is naturally inclined to) as though it were the former. A fit and healthy adult doesn't necessarily need many, or even any, carbs for long distance running (provided they're getting enough of everything else, at least), but when they start lifting and moving heavy loads, digging, sprinting, etc? the carbs become quite necessary. And, of course, there's the matter of food storage. It seems like the human body is set up such that carbohydrates are quite significant to the body's ability to get through periods of shortage of anything else.

@billzusner4873 'always' eating the liver is fine... provided you only hunt things that have livers that are suitable for consumption. There are a number of differnt animals where eating the liver will straight up kill you, despite other parts of the animal being very good food.

@MollyHJohns You have to be a bit careful with animal organs... the same organ in some animals is very good eating and in others is toxic enough to kill you. Also there's a long history of media reacting to a similar history of organs being cooked... Badly... for various reasons, and consequently putting people off them entirely. Still, the right organs cooked well are absolutely something that should be more common in many people's diets than they are.

@pauls3075 ... it can be a later defintion of the word. It doesn't make it less valid, because that's how langauges work. English particularly Loves turning other word types in to verbs, as is the case here.

How much you do or do not need carbs depends on how much of what you are doing for how long. Fit and healthy humans are pretty much Optimised for long distance running. Hard labour, on the other hand, is a different matter, as is anything requiring significant mental activity. Sugars are particularly useful for the latter, and humans are wired around the assumption that sugars are going to be... not scarce, exactly, but generally available only in small quantities at a time, so should be eaten whenever they're availalbe. This, of course, runs into problems when encountering modern food (and 'food') production processes. There's other factors involved too... the ultimate conclusion of which is that you Should be eating Some carbs, but most people's diets include substantially more carbohydrates than they really should. (mind you, Potatoes are also SUPER nutrient dense, provided they were grown in good soil. Grains, not so much).
