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.
