In January 2026, Peter Rahal—the chief executive officer of David Protein (legally, Linus Technologies, Inc.), a New York–based health food brand—faced a class-action lawsuit over allegedly misleading calorie claims. David protein bars were marketed as offering 28 g of protein with only 150 calories, using esterified propoxylated glycerol, a fat substitute contributing fewer calories than conventional fat. Should Rahal position the bars using total calories, which is easier for consumers to understand, or metabolizable energy, which more accurately reflects scientific reality? Should he revise labelling and educate consumers, or continue defending the company’s existing approach without changing its marketing communications?

Learning Objectives

The case is intended for undergraduate- and graduate-level courses in strategic marketing, IMC, consumer behaviour, and consumer policy. Topics such as consumer cognitive overload, nutrition labelling, and marketing communication strategies are typically introduced early in IMC and consumer behaviour courses. The case can therefore be used mid-semester, after instructors have covered foundational concepts in business strategy, consumer perception, and competitive positioning. Instructors are encouraged to supplement the case with research articles rather than relying exclusively on a single textbook when discussing the underlying concepts. After working through the case and assignment questions, students will be able to accomplish the following objectives:

Evaluate the communication challenges that arise when firms market scientifically complex food innovations to consumers who rely heavily on simplified front-of-pack cues and heuristics.
Critically analyze whether CEOs should proactively educate consumers about novel ingredients and scientific methodologies or primarily rely on legal and regulatory compliance defences during consumer lawsuits.
Assess how lawsuits and allegations of misleading claims can influence consumer trust, brand perception, and spillover attitudes toward the broader functional food category.
Develop post-crisis integrated marketing communications (IMC) strategies that balance scientific credibility, transparency, consumer understanding, and brand positioning after a reputational controversy.
