This is just more keto pseudoscience. Unfortunately people care more about YouTube videos than what reputable sources say: https://www.niddk.nih.gov/health-information/diabetes/overview/symptoms-causes#type
Not disputing that excess fructose can cause liver damage, but most studies demonstrating this have mice ingesting absurd amounts. This doesn’t happen when you are eating a normal amount of food anyway. Excess water can kill you, but no one avoids drinking water because of this.
You don’t have the same incentive to quit sugar either. It’s not illegal, it won’t make you crash your car and kill someone, the police won’t arrest you for driving under the influence of sugar, you won’t lose your job because you were caught using sugar, your family won’t leave you because of your sugar habit, strangers won’t feel ashamed or depressed if they see you using sugar in a public place etc.
Sure, there is obesity and diabetes, but they are directly caused by an excess of calories, not sugar. Sugar might make you eat more, or so people say, but does it really? You can still overeat plenty of greasy salty stuff.
