Social Media Trends Push Protein And Fiber “Maxxing”

First it was protein, now fiber: the “maxxing” mindset has swept social media, with wellness influencers urging followers to consume as much of certain nutrients as possible for a “life-changing” gut glow-up or health boost.

Proteinmaxxing, the earlier craze, promoted high intake of protein from foods like meat, dairy, and nuts to support functions like tissue repair and immune health. Now, fiber is emerging as 2026’s trending nutrient, with influencers encouraging massive consumption of oats, chia seeds, beans, and other high-fiber foods to curb hunger and improve gut health.

Brands have eagerly joined the trend. Sugary cereals, prebiotic sodas, and chips now boast added protein or fiber, as companies from PepsiCo and Nestlé to startups like Olipop capitalize on the craze. “I think fiber will be the next protein,” said PepsiCo CEO Ramon Laguarta.

Surveys show that Gen Z and Millennials are leading the charge: nearly half of US consumers are trying to eat more protein, while 40 percent of Gen Z and 45 percent of Millennials say they’re working on gut health.

Nutritionists caution, however, that more isn’t always better. Andrea Glenn, assistant professor of nutrition at New York University, described the fiber trend as “pretty tame” compared to other wellness crazes. Samantha Snashall, a registered dietitian at Ohio State University, noted that fiber has been “undervalued” for years, even as protein became the “special child” of nutrition trends.

Experts warn that blindly following social media advice can be risky. Arch Mainous, a professor of community health at the University of Florida, emphasizes that people should focus on recommended daily intakes rather than assuming “if one’s good, five’s better.” He also highlighted the dangers of trusting influencers, many of whom lack scientific training and may have commercial interests.

Practical advice remains simple: aim for a balanced intake. The American Heart Association recommends a combination of milk, yogurt, lentils, and lean meat or fish for daily protein targets. For fiber, adults should aim for 25–38 grams per day from whole foods like beans, fruits, vegetables, nuts, oats, and quinoa. Gradually increasing fiber intake is key—rapid spikes can upset the digestive system.

Finally, no single nutrient is a cure-all. While fiber-rich products can support health, they cannot replace a balanced diet or fix all problems. “Slow and steady wins the race,” nutritionists emphasize, reminding consumers that whole foods, variety, and moderation remain the cornerstone of good nutrition.
