The True and Total Cost of a Mocha Latte

How much does a mocha latte really cost? According to
Deborah McNaughton and Melinda Weinstein, authors of the new book "Rich and Thin: Slim Down, Shrink Debt & Turn Calories Into Cash, " the answer is  $871 and about 104,000 calories a year. And as Washington Post writer Michelle Singletary points out, if you get a 69-cent doughnut, you can add $179.40 a year and 46,800 calories.
Singletary likes the book, whose main claim is that the hidden costs, from higher insurance premiums to more hospital visits, is crushing people’s bank accounts.
Singletary is especially high on the book’s  "Money Calorie Counter," which details how much you can save by investing the money not spent on unhealthful foods. Read more.
