Don't rely on restaurants to count calories for you...
Turns out, there are quite a few calorie miscalculations.
A Tufts University study shows nearly one out of five restaurant dishes has at least 100 calories more than what the restaurant claims.
These underestimated foods came from several chains including Chipotle Mexican Grill, Olive Garden, Boston Market and Outback Steak House.
Researchers bought food from these places and tested them in the lab.
The scientists also found that sit-down restaurants were more likely to have inaccurate readings, likely because the chefs have more leeway in cooking.
A new federal law will require calories on menus at large chain restaurants in the next year.
