David Protein Bars Face Class-Action Lawsuit Over Misleading Nutrition Labels

David Protein, a rapidly growing brand known for its high-protein, low-calorie bars, is embroiled in a class-action lawsuit filed in January 2026 in the Southern District Court of New York. The lawsuit alleges that the bars contain significantly more calories and fat than advertised, potentially misleading health-conscious consumers. Plaintiffs claim independent laboratory tests revealed that the bars contain up to 83% more calories and 400% more fat than the nutrition labels indicate.

The lawsuit specifically targets Linus Technologies Inc., the parent company of David Protein, accusing it of deceptive marketing practices. The plaintiffs assert that the bars, which are marketed as containing 150 calories and 2 grams of fat, actually contain between 263 and 275 calories and 11 to 13.5 grams of fat. These discrepancies exceed the FDA's allowable margin of error for food labeling, which permits a 20% variance.

Peter Rahal, the founder of David Protein, has publicly defended the accuracy of the product labeling. In a letter to customers, he stated that the lawsuit is based on a flawed interpretation of how calories are measured, particularly concerning the ingredient esterified propoxylated glycerol (EPG), a fat substitute used in the bars. Rahal argues that the testing method cited in the lawsuit, bomb calorimetry, inaccurately reflects the caloric content of EPG, as it measures total heat released when food is burned, including calories that the body does not absorb.

The allegations have raised concerns among consumers who rely on accurate nutritional information for weight management. The lawsuit claims that misleading labeling has allowed David Protein to charge a premium price for its products, which are marketed as healthier snack options. Some consumers, like Lucienne Diaz, have expressed feelings of betrayal upon learning about the lawsuit, while others, like Courtney Thurston-Del Buono, remain skeptical about the claims.

The case could have significant implications for food labeling standards, particularly regarding newer ingredients designed to reduce digestible calories. The plaintiffs are seeking damages, restitution, and changes to the company’s labeling practices. As the lawsuit unfolds, it may prompt a reevaluation of how nutritional information is presented to consumers, especially in the health and wellness market.

In his defense, Rahal emphasized that David Protein's labeling complies with FDA regulations and that the claims in the lawsuit reflect a misunderstanding of scientific principles regarding calorie determination. He stated, “Our products are labeled correctly and in full compliance with all FDA regulations. The claims in this lawsuit are meritless.”
