Glucose is not an "empty" and addictive "calorie." It is a primary nutrient, like water, air and salt. Once understood, then everything starts to make sense. Yes, depriving the body of "sugar" can lead to rapid weight loss, but starving the body of glucose cannot be a long-term healthy life-style (unless you are an Intuit Eskimo, and even they have lost the gene for ketosis and no longer go into ketosis.

Should I stop fruit?
Your fructose question is good. Keep eating fruit.
I think we know the answer about fructose being both good and bad thanks to Linus Pauling's book HOW TO LIVE LONGER AND FEEL BETTER, and his reference to Yudkin's book Sweet but Deadly. We all need to make some fat. That's how we survived through winters and during ice ages.
Fructose is a Fat On switch. Thanks to this documentary, which cites the book The Fat Switch (on our reading list)

around minute 6, we know the mechanism that causes the liver to manufacturer human fat. (Incidentally, uric acid prompts the liver to make fat.)
Eating fruits, we create and store fat in the summer that we burn during the winter. The key is that that eating fruits provides about 10 grams of fructose daily.
Enter the real bad guy: table sugar, sucrose - 1/2 glucose and 1/2 fructose. The Yudkin book Pauling cited informs us that at that time, people were eating 100 grams per day of sugar, of sucrose. This means they were eating 50 grams of glucose, but instead of 10 grams of Fructose, people in modern societies can eat something like 50 grams of fructose, or four times more than they would get simply eating fruit. Today, "sugar" is in everything, and lucky we even have "high fructose corn syrups"
Fructose in fruits is necessary so we don't waste away. Don't worry about eating fruits.
There are two known metabolic pathways to uric acid, as shown in the above Low Salt, More Fat documentary.
#1. Fructose (makes sense, we store fats when fruits are available) and
#2 LOW SODIUM also turns on the same (uric acid) switch.
Now we know how to keep the liver from producing fat. And thanks to Anthony, we know that the liver is where fat is made. (Didn't sound right when I first read MM. Also, we eat fat, but that is a different story.)
All coming together into a clear picture or unifying theory.
We know, glucose is like "air and water and salt" to the liver and brain (Thank you Anthony). Everyone on Keto believes that "carbs" are empty calories and that we crave sugar from addiction, like we crave alcohol or cocaine.
Once we understand that if we deprive our body of glucose - it will adjust to spare glucose for the brain/liver - by making other parts of the body insulin resistant. If muscles become insulin resistant, glucose won't be able to get into muscles, for example, so the body quickly becomes "fat adapted" and burns fat instead of glucose. This is good "insulin resistance" and a few aware N.D.s realize this condition is not necessarily bad. But they don't know why. Now readers here do. The brain and liver cannot burn fat, which is why glucose is not an "empty calorie."
And this is ultimately why keto, by restricting sugar (carbs), can lead to rapid fat loss. The body knows its in trouble from a lack of glucose.
Ergo glucose intake can be a regulator on how fast people lose weight. Eating less glucose is like pushing on the "fat burning" gas pedal.
However, you can reduce ordinary table sugars, and only take glucose, not make fat, and still burn fat, just not as fast. In fact, you can burn both glucose and fat at the same time, in different parts of the body.
