I mean, it’s not that far off. Take this guy who ate only twinkies/nutty bars/donuts/doritos for a month (with some veggies added in for fiber/ruffage):
> His body mass index went from 28.8, considered overweight, to 24.9, which is normal. He now weighs 174 pounds.
> But you might expect other indicators of health would have suffered. Not so.
> Haub's "bad" cholesterol, or LDL, dropped 20 percent and his "good" cholesterol, or HDL, increased by 20 percent. He reduced the level of triglycerides, which are a form of fat, by 39 percent.
I mean, yeah, of course if you eat less than your body needs, you will lose weight, nobody is denying that. You can lose weight drinking only coca cola every day. Now, how _easy_ that would be, how much hunger one would feel, the effect on health, mental health, energy, what the rebound is after the diet is done etc., that's a completely different discussion. And another discussion is how much the weight loss is sustainable/maintainable in the long term.
So yeah, in a vacuum, with a perfectly spherical cow, it's not that far off.
