But after one of the L.A. customers left feeling “excessively full,” he had a sneaking suspicion that number was much higher.

Chipotle confirmed on Twitter that the 300-calorie count refers to just the chorizo-not the rest of the fixings, like the tortilla, white rice, black beans, salsa, and cheese.

Once you add those extras, that 300-calorie burrito becomes a whopping 1,050 calories, according to reporters from Slate, who did the math using Chipotle’s online nutrition calculator.

The customers who are suing Chipotle claim the chorizo sign falls into a pattern of misleading nutritional information from the chain. That’s why their suit would cover “all people who bought food at Chipotle for four years leading up to the filing of the complaint,” according to Slate.

But even if the burrito had been labeled at 1,050 calories all along, research suggests it might not have changed the customers’ orders.

In a study from New York University, only 8 percent of the 700 fast-food customers surveyed made a healthier choice because of calorie labeling.
