According to an AP story,
Researchers in Boston found that an unusually heavy meal roughly quadruples the ordinary risk of a heart attack during the two hours after eating.
"The risk is especially high - 10 times normal - during the first hour after pushing away from the table. But after three hours, the extra risk is almost gone."
So what is the conclusion? Stop gorging? Or make sure not to exert oneself whatsoever after gorging, so as to minimize the danger of a heart attack?
