Anyone who is not taking in enough energy to function and has to turn to the body’s stores for energy is starving. The fact that some people have greater stores to draw from doesn’t change what’s happening in the body.
I’ve never read any science supporting this assertion, quite the opposite: the starvation response is what makes dieters act exactly the way the men in that study acted.
It doesn’t matter how “people” understand it, it’s how the body understands it. When you stop eating enough to support your needs, your body will perceive it as starvation and among other things you will find yourself obsessed with food, and when you stop white-knuckling through the ridiculous food obsession you’ve created in yourself you will almost certainly eat more than you did before and end up fatter than you were before.
And we have the proof that this is exactly the way it works from sea to shining sea, in the millions of us who went on a diet to lose a few pounds and found ourselves 100+ pounds fatter 20 years of such diets later. It’s really kind of funny that you would argue that the Keys study doesn’t mean anything when the experience of millions of people confirms it.
Honestly, on what basis is the suffering described by these men in this study so special and different than the suffering described by people on diets? It’s shocking and disturbing in the context of the study, but in the context of the fat person next to you they should just suck it up? Please.
Well, if it were actually tolerable I daresay a helluva lot more people would tolerate it, seeing as how the alternative is pretty damned miserable as well. But the overwhelming avalanche of evidence crushing us under its collective weight is that people absolutely do not tolerate it, making it perfectly accurate to describe it as intolerable.
