you are right now I better understand what you meant.

That was the part that confused me.

"If it does negate the benefit than that would suggest that the entire benefit from the beige fat is from putting the body in a calorie deficit, and you would then expect the exact same effectiveness from calorie restriction"

As far as I understood the paper its beige fat that can eat away food from cancer and not white fat. And afaik calorie restriction doesnt augment beige fat. My error was thinking you meant calorie restriction while having white fat but you meant with beige fat? And yes this makes sense.

And I thinked autophagy because this is the main "thing" happenkng while fasting which is not burning body fuel

thanks for the answer
