In 2025, Burger King became the defendant in a significant class-action lawsuit alleging false advertising related to its signature Whopper sandwich. The lawsuit accuses Burger King of materially overstating the size and amount of meat and ingredients in its Whopper ads compared to what consumers actually receive in-store. This article provides a detailed overview of the lawsuit background, key claims, court rulings, Burger King’s defense, and the broader implications for advertising standards in the fast-food industry.
Background and Core Allegations
The lawsuit was initially filed in 2020 by 19 customers from 13 states, represented by The Russo Firm. It alleges that since 2017, Burger King’s advertising materials—including in-store menu images and promotions—depicted Whopper sandwiches as approximately 35% larger and containing more than double the meat than the actual product served to customers. Plaintiffs claim the burgers shown in ads feature oversized patties and ingredients overflowing the bun, which misleads customers about product size.
- According to the plaintiffs, Burger King’s promotional photos misrepresent the real size of the Whopper by showing a larger, more appetizing sandwich that customers do not receive.
- The lawsuit argues that these false representations influenced customers’ purchasing decisions and that they would not have paid for the products had they known their real size.
- Other fast-food chains including McDonald’s, Wendy’s, and Arby’s have faced similar lawsuits alleging false advertising of burger sizes.
Legal Proceedings and Court Rulings
In May 2025, U.S. District Judge Roy Altman in Florida ruled that the lawsuit could proceed, rejecting Burger King’s motion to dismiss. The court found that the claims “go beyond mere exaggeration or puffery” and could plausibly mislead reasonable consumers about the actual size and quantity of Whopper ingredients. However, claims related to television and online advertising were dismissed, leaving in-store advertising as the primary focus of the lawsuit.
Judge Altman emphasized that determining whether the discrepancy between the advertised and actual product size influenced purchasing decisions is a factual issue best left to jurors. Plaintiffs’ allegations of negligent misrepresentation, breach of contract, and unjust enrichment will be examined further in court.
Burger King’s Defense
Burger King denies the allegations, arguing that the flame-grilled beef patties used in advertisements are the same as those served to customers nationwide. The company asserts that food styling is a common and accepted industry practice to make items appear more appealing, and reasonable consumers understand that menu photos are designed to showcase products attractively rather than serve as exact replicas.
Burger King has also stated that product descriptions, such as labeling the Whopper as “a ¼ pound of flame-grilled beef,” provide clear information about portion sizes. The company sought the dismissal of the lawsuit on the grounds that the differences in appearance are not actionable fraud or misrepresentation.
Broader Implications and Industry Impact
- The case highlights the growing legal scrutiny of food advertising practices and pushes for greater truthfulness and transparency in marketing.
- It may affect how fast-food chains present their products in promotional materials, encouraging more accurate depictions to avoid misleading consumers.
- The verdict could set precedent regarding the balance between reasonable advertising puffery and actionable false representation claims in the food industry.
- Similar lawsuits against other major chains indicate an industry-wide reassessment of marketing approaches and consumer rights.
