Don't call it dieting. It's 'biohacking'

ONE night in college, a member of my four-person study group showed up with a bunch of Snickers bars from a campus giveaway. The only man in the group picked one up and casually read the nutrition label.

"Whoa, you'd never guess how many calories are in just one of these," he said.

Without missing a beat, the women raised our tired heads from our textbooks, collectively muttered "Two hundred and eighty" and then went back to solving parametric equations.
