One think I like here is the continual glucose monitoring, that's relatively new, so a bit different from previous studies looking at appetite versus glucose at particular discrete moments in time. This study does make sense to my personal experience, although I don't have that glucose monitoring--it just makes sense with how I experience appetite when eating different ways. I'm much leaner eating to a more ketogenic ratio.

What dieting lacks is feedback. Day to day, the scale tells nothing about energy balance. If there was something that could tell you that, with certainty, throughout the day, I think that would make all the difference in the world. Maybe what's needed is a subtle energy deficit, to be sustainable--but we're not even sure we're in a deficit, until we're far beyond subtle.
