For generations, nan Meives family made cheese. Tony Meives’s grandfather, a Swiss immigrant, and his begetter some ran mini food factories successful Wisconsin, successful nan bosom of America’s dairyland. “I worked successful nan food mill my full life,” Meives says. “I person 4 world-class cheesemakers successful my family.” But erstwhile it came clip to inherit nan family business, Meives recovered location was much money successful nan business runoff that his grandfather would person erstwhile thrown away. Today, nan 39-year-old bodybuilder and gym proprietor runs a institution that sells whey macromolecule powder, nan watery byproduct of cheesemaking that was erstwhile considered waste. “Twenty years ago, nan only group who took whey were bodybuilders,” he says. “Over nan past 5 years, nan marketplace has really opened up to each and each type of personification you tin astir apt deliberation of.”
When Robert F Kennedy Jr, nan US wellness secretary, declared precocious past month, that “the warfare connected macromolecule is over”, he sounded a spot for illustration 1 of those Japanese soldiers of 2nd world warfare lore, who spent years bunkering successful nan jungles of south-east Asia, oblivious to nan truth that hostilities had agelong ceased. Perhaps location was a clip erstwhile proposal leaned much towards a fare based astir fruit, vegetables and carbohydrates – but by May 2026, nan warfare connected macromolecule was surely over. Protein had won.
You tin spot its triumph parade successful each supermarket aisle successful nan US – meal cereals, stiff foods, moreover iced lattes person been souped up pinch other protein. Not moreover accepted “junk foods” specified arsenic nacho chips, microwave ramen and pretzels are safe. According to a 2025 survey of 3,000 US adults, 71% said they were trying to eat much protein, up from 59% successful 2022. “A batch of different brands are connected nan macromolecule bandwagon,” Meives says. “They’re putting it successful everything.”
The taste inclination towards “proteinmaxxing” has driven request successful whey protein, which was antecedently considered small much than effluent by astir dairy farmers.
“It’s a byproduct nary longer,” says Joshua White, vice-president of dairy ingredients astatine Missouri-based dairy marketer and trader TC Jacoby & Co. “Whey is simply a co-product now.”
As keen readers of Little Miss Muffet whitethorn already know, whey is made during various dairy and cheesemaking processes. Enzymes are added to dairy milk, which causes nan desirable curds to abstracted from nan (previously little desirable) watery liquid called whey. Prior to nan macromolecule boom, nan leftover whey was often utilized arsenic provender aliases fertilizer, aliases reprocessed into different forms of soft food (ricotta takes its sanction from nan Italian connection for “recooked”, because it was traditionally made by letting whey ferment and past reheating it.) Trying to find thing to do pinch whey is simply a millenia-old puzzle: astir 460 BC, nan ancient Greek medic Hippocrates prescribed whey serum to his patients successful bid to fortify their immune systems.
To make whey powder, liquid whey is filtered to region fats and carbohydrates, past purified, evaporated and spray dried, producing a powder which tin beryllium mixed into macromolecule bars aliases blended successful a shake.
Initially whey macromolecule was marketed to powerlifters, gym rats and group who owned their ain shaker cups. But nan caller macromolecule roar has made whey truthful celebrated that producers are facing shortfalls. “We’ve reached nan constituent wherever location are shortages,” says Dean Sommers, a food and nutrient technologist astatine nan University of Wisconsin’s Center for Dairy Research. “There are a batch of unfilled orders, and request for orders. There simply isn’t capable merchandise astir to capable those orders.”
In response, immoderate manufacturers are adding caller equipment, to thief nutrient much whey. Leading manufacturers are building full caller facilities.
All this request intends that successful nan past fewer years, nan value of whey macromolecule concentrates has changeable up as overmuch arsenic fivefold. In nan past 2 years alone, nan value of whey concentrates has accrued as overmuch arsenic 83%. At nan aforesaid time, request for dairy and food products has remained comparatively stable, meaning location whitethorn soon beryllium a constituent wherever whey request and curd request are retired of whack.
“Whey macromolecule is presently driving much a percent of nan farmer’s cheque than it ever has before,” says dairy trader Joshua White. “That results successful nan imaginable of excess food production, successful bid to get to that whey. The cart is driving nan horse.”
There are, successful nan history of cultivation production, immoderate precedents for this. Chicken wings were regarded arsenic undesirable excess until, arsenic nan fable goes, an industrious cook from Buffalo, New York, thought to fry them and slather them successful basking sauce. Now, chickenhearted wings are truthful celebrated that they’re 1 of nan superior drivers of poultry prices, pinch request for wings surpassing that for nan remainder of nan bird. (It’s estimated that Americans eat astir 1.5bn wings connected Super Bowl Sunday alone.)
The narration betwixt whey and nan broader dairy marketplace whitethorn beryllium headed towards a akin disequilibrium. In bid to caput disconnected a lawsuit wherever producers are stuck pinch excess cheese, dairy boards person progressively looked to export markets successful Latin America, China and arsenic acold distant arsenic nan Pacific Islands.
The whey roar is astatine slightest partially attributable to nan fame successful GLP-1-style weight nonaccomplishment drugs, which astatine slightest 1 successful 8 Americans admit to taking. As caloric intakes are tightened, macromolecule depletion becomes moreover much important.
It’s estimated that anyplace from 25-40% of weight mislaid during GLP-1 therapies is thin muscle. Drugs specified arsenic Ozempic, Wegovy and Zepbound do not separate betwixt thin musculus and adipose insubstantial (better known arsenic fat). The drugs’ superior effects – regulating hunger signaling and gastric motility – person a much drastic effect connected macromolecule synthesis. Simply put, galore group connected these narcotics are not quiet capable to eat nan recommended dietary allowance of protein.
“I was decidedly concerned astir losing musculus alongside nan different weight,” says Alex Sullivan, a 41-year-old who precocious started taking Tirzepatide and upped his macromolecule intake successful turn. “Doctors talk astir really you suffer musculus wide arsenic you get older, and you should effort to support arsenic overmuch musculus wide arsenic you can. I wanted to make judge I retained arsenic overmuch arsenic possible, arsenic I mislaid weight.”
There is, however, a ceiling. It’s generally recommended that astir adults purpose for 0.8 grams of macromolecule per kg of assemblage weight (or astir 0.36 grams per pound). But investigation by Ian Neeland, a Cleveland-based cardiologist who specializes successful diabetes, obesity and cardiovascular health, suggests that macromolecule intake and musculus synthesis does not standard exponentially. In fact, it plateaus aft that double-the-recommended-daily-allotment target is hit.
“The musculus building didn’t really amended aft 1.6 [grams per kg of bodyweight],” Neeland says. “You really conscionable request to eat capable macromolecule to sphere musculus mass. It’s much astir preservation.” In different words, much macromolecule whitethorn beryllium cardinal for those connected GLP-1s looking to clasp muscle. But manic, whey-gobbling proteinmaxxing whitethorn not do overmuch to execute this goal, accomplishing small beyond driving up nan value of whey.
If Ozempic and its chemically related cousins are sounded arsenic “wonder drugs”, past whey macromolecule tin look nary little singular – a comparatively easy measurement to mitigate GLP-1s deleterious effects connected musculus and macromolecule synthesis. But request successful whey powders is creating its ain raft of broadside effects connected nan dairy and cheesemaking industries. While US food depletion remains comparatively dependable – a spokesperson from Vermont’s agency of agriculture tells maine that nan mean American consumes much than 40lbs (18kg) of food per twelvemonth – dairy farmers are pivoting to different protein-rich products: yoghurt and moreover cottage cheese, those erstwhile maligned, nutrient-rich, wiggly curds that (seasoned pinch ketchup) were a staple of President Richard Nixon’s spartan regular diet. “There’s cheddar food manufacturers that are switching complete to cottage cheese,” said Sommers connected nan measurement macromolecule has upended nan industry.
This month’s reporting from nan US Department of Agriculture shows that nan whey value is only growing, while proviso is shrinking. Some retailers, for illustration Tony Meives of Wisconsin, who buys whey from a wholesaler, interest that whey will go truthful costly it’ll extremity up threatening his business and nonstop price-conscious consumers flocking to nan cottage food aisle. “I dream less group return whey protein!” he laughs. “That measurement nan value does travel down, and nan costs to make it drops.”
