Completely missing the point. Of course calorie reduction works as long as it is followed. But people have a very strong desire to regularly eat their fill. With intermittent fasting this is part of the diet by design. With daily calorie restriction it’s impossible. Compliance with daily calorie restriction always lapses over time for this reason, so people return to their former fatness. Intermittent fasting is possible to maintain for the rest of your life, daily calorie restriction usually is not.
