The Ultra-Extreme Calorie Restriction Diet Test -- New York Magazine:
It’s 7:30 p.m. in Soho, that magic hour when the scent of first-course dishes wafts heavenward from the tables at Savoy, the anxiety of last-minute meal planners courses through the aisles of Dean & DeLuca, and a grown man’s fancy turns to thoughts of food. My own thoughts, at the moment, are of practically nothing else. Half-sprinting through the Prince Street crowds, I am late for a dinner party I’ve been planning for weeks, and I’m starving.
I’ve been starving for the past two months, actually, and that’s precisely what the party is about: My dinner guests—five successful urban professionals who for years have subsisted on a caloric intake the average sub-Saharan African would find austere—have been at it much, much longer, and I’ve invited them here to show me how it’s done. They are master practitioners of Calorie Restriction, a diet whose central, radical premise is that the less you eat, the longer you’ll live. Having taken this diet for a nine-week test drive, I’m hoping now for an up-close glimpse of what it means to go all the way. I want to find out what it looks, feels, and tastes like to commit to the ultimate in dietary trade-offs: a lifetime lived as close to the brink of starvation as your body can stand, in exchange for the promise of a life span longer than any human has ever known.
