Whey protein, once a discarded byproduct of cheesemaking, has become a multi-billion dollar industry, driving shortages and price hikes, and reshaping the entire dairy market due to health trends and the popularity of weight-loss drugs.
For generations, whey, the watery byproduct of cheesemaking, was considered waste. However, it has undergone a dramatic transformation into a highly valuable co-product, now driving significant changes in the dairy industry. The shift is exemplified by Tony Meives, whose family were traditional cheesemakers, but he now runs a successful whey protein powder company. This boom is fueled by a widespread cultural trend of "proteinmaxxing," leading to protein being added to nearly every food item, from cereals to lattes. Critically, the rise of GLP-1 weight-loss drugs (like Ozempic and Wegovy) has significantly boosted demand, as users require increased protein intake to preserve lean muscle mass during weight loss. This unprecedented demand has led to severe shortages of whey protein concentrates, with prices soaring up to fivefold in recent years. Dairy farmers are now prioritizing whey production to the extent that it's impacting their overall checks more than cheese, creating a scenario where "the cart is driving the horse" and potentially leading to an oversupply of cheese. Manufacturers are responding by investing in new equipment and facilities. While protein is vital, especially for those on GLP-1s, research suggests that protein synthesis plateaus after a certain intake (around 1.6 grams per kg of body weight), indicating that excessive "proteinmaxxing" may primarily inflate prices rather than offer additional muscle benefits. The whey boom is reshaping the dairy landscape, with some cheese manufacturers even switching to producing other protein-rich products like cottage cheese, and raising concerns among retailers like Meives about the sustainability of soaring whey prices.
