A class action lawsuit has been filed alleging that David protein bars have more than 400% more fat and 80% more calories than advertised. The complaint has been compared to the film "Mean Girls" where the character finds out that the "healthy" diet bars are making her gain weight, not lose it. The company's founder, Peter Rahal, responded to the lawsuit, stating that the issue lies in the wrong measurement and method to measure calories. The lawsuit does not specify the method used to measure the calories.
