Correction: An editing glitch in the June 9 Get Out column inadvertently created confusion in two sentences. One sentence should have read: “Talbot says a low- or no-carb diet has serious drawbacks, and athletes should not use it to ‘make weight.’ ” Another sentence was supposed to be written: “When it comes to weight loss and exercise, the whole fat-burning, carb-burning issue is surprisingly complicated. But the cold equation is still the same: it’s all about calories, not what your body uses for metabolic fuel.” In print, they implied an opposite meaning.
