Sorry, but your statement is as true as it's pointless.
Consider: healthy people who are injected a small dose of insulin experience tiredness (reduced energy use) and increased hunger.
Contrary to eating fats, eating carbs triggers the release of insulin. Young, healthy people who have a properly working endocrine system handle eating carbs fine. But for those who don't, it's a different story. Just like those test subjects, their body limits energy consumption and experiences constant hunger.
So yeah, they don't burn enough calories and eat too much of them, but the saying so is pointless if not insulting; the question that needs addressing is why.
I'm not trying to say keto isn't helpful. If it works for you that's great, go for it. It may even be better than other diets in certain scenarios as you have mentioned.
However prescribing it as the default solution isn't right. If you're gaining weight the default solution is to reduce total calorie intake. Most of the benefits people see on keto can just as easily be had by simply avoiding processed junk foods. Demonizing carbs is counterproductive as it causes people to needlessly exclude nutritious foods like fruits from their diet. Yes, you will feel hungry on a low calorie diet initially. Keto will also give you the "keto flu" in the first week. Later on your body adapts to it (in both diets). The insulin release and hunger is your body's primary mechanism developed over hundreds of thousands of years. If you're advocating bypassing that in favour of something else, you better have a very good reason to do so.
