Getting into a keto state is by the far the fastest and most reliable way to lose weight. Probably also hard to maintain as it can be hard to get that full feeling like you do with carbs.

It is the same diet which professional bodybuilders use. And they know EVERYTHING about how to lose weight since every % of body fat they lose can make a massive difference in muscle definition.

Schwarzenegger's book on bodybuilding (which I read in the late 90's) had a fairly long section on ketosis. He actually bought urine testing strips to make sure he didn't go into ketosis. When cutting, he reduced his carbohydrate intake, but he immediately increased it again at the first sign of ketosis for reasons he explained in some detail. AFIK, most successful bodybuilders eat tons of carbs while bulking and then try to go as low as possible without going keto while cutting.

Bodybuilders generally have not bothered with keto, until recently.

They just do the standard bulk (overeat in the off season, gain muscle and fat) in the off season and cut (heavy calorie restriction to cut the fat) to look good on stage.
