In late July, nutrition experts warned that the surge in high‑protein diets—especially those based on heavily processed, fortified products—can cause bloating, dehydration, kidney strain and other health problems. They highlighted symptoms such as abdominal gas, frequent urination and reduced exercise performance, and advised consumers to prioritize whole‑food protein sources and keep intake to 1.2‑1.6 g per kilogram of body weight. By early August, experts reiterated that most people meet their protein needs without supplements, noting that excess intake offers limited benefits for muscle growth and can displace other nutrients or add unwanted sugars, fats, and additives. They emphasized that only specific groups, such as high‑performance athletes, older adults, or those recovering from illness, might require higher amounts under professional guidance. Mid-August reports highlighted the influence of the food industry, which labels various products like bars, yogurts, and cereals as ‘high‑protein’ to suggest more is always better. In Brazil, data from an Atlas/Intel survey showed that 30% of consumers are influenced by protein labels, while 37.9% are motivated by social media. Nutrologist Monize Aydar clarified that while there is no strict metabolic maximum, there is a limit to how much protein effectively stimulates muscle protein synthesis. By late August, warnings expanded to include the risks of ultra-processed foods marketed with labels such as ‘fit’, ‘zero sugar’, or ‘high protein’. ~~Experts noted these products often contain high levels of sugar and carbohydrates.~~ Recent updates emphasize that labels like ‘vegan’ or ‘sugar-free’ can be deceptive marketing tools, and consumers should prioritize checking ingredient declarations on the back of packaging. Furthermore, research published in the ‘Journal of Health, Population and Nutrition’ links high intake of ultra-processed foods to an increased risk of metabolic dysfunction-associated steatotic liver disease (MASLD). In late August, nutritionists further cautioned that high-protein packaged goods, such as yogurt and snacks, often contain high levels of sugar and carbohydrates.
