Five nights ago, I dreamed I was trapped at a houseboat party. The decks heaved with music and laughter; people swayed, bottles clinked, lights shimmered across the water. Somewhere between the bass thump and the spray of cheap champagne, I decided it was time to save everyone. I climbed onto a railing and began lecturing on the virtues of a high-protein diet.
The crowd ignored me. The more I shouted about the glory of amino acids, the louder the DJ turned the volume. My words scattered across the lake like crumbs for fish. I tried compromise—lowering the daily requirement from 200 grams to 120—but no one cared. Eventually, hoarse and defeated, I realized I’d become a mad prophet of whey protein, screaming into the void. When I woke, I asked myself the obvious question: Had I gone overboard on my protein obsession?
That question lingered until this morning, when I read Julia Belluz and Kevin Hall’s Food Intelligence: Protein, the “Only True Nutrient.” They argue that our worship of protein is centuries old. In 1853, a Parisian newspaper mocked vegetarians as gaunt weaklings too frail to walk out of a restaurant unaided. A hundred years later, Arnold’s gospel of 250 grams a day turned protein into a civic duty for gym rats. Now, with Google searches and supplement sales hitting record highs—an industry worth $28 billion—protein has become both religion and racket. Everyone preaching its holiness seems to be selling tubs of it.
Protein has always been marketed as a competitive edge: animal protein supposedly bestows power, plant protein supposedly punishes you with mediocrity. Yet Belluz and Hall dismantle this myth. Plant eaters, they write, can easily get all essential amino acids from a diverse diet—no powders, no “meat extract,” no panic required.
Even more humbling, they admit that no one actually knows the optimal daily dose. Our bodies, they say, have a built-in governor called “protein leverage,” which drives us to crave roughly what we need. Too little protein and we lose muscle, which shortens life. Too much—especially at the expense of a balanced diet—and we hasten the same end. Somewhere between the extremes lies the sweet spot, but it’s not a round number you can print on a supplement label.
That answer frustrated me. I like numbers. I like goals. “More” has always felt safer than “enough.” Reading their chapter, I remembered the summer of 1978, when I was sixteen and backstage with Mr. Universe Mike Mentzer before his posing exhibition set to 2001: A Space Odyssey. I asked how much protein he ate. “About a hundred grams,” he said, barely looking up from his shake. I was stunned. Arnold had taught us to eat at least 250.
“Why not more?” I asked. Mentzer shrugged. “It’ll just make you fat.” Then, with equal candor, he mentioned his steroid stack—Deca-Durabolin included. Even then I could tell: genetics, not shakes, were the true miracle. At five-foot-eight and 225 pounds, he was carved from marble, but it was marble under pressure. He died of heart failure at 49, just five miles from where I live.
Now I’m 64, taking in 180 grams a day and wondering if I’ve turned protein into a creed. I’m strong for my age but heavier than I’d like. Maybe the excess that built my muscle also built my burden. That houseboat dream feels less like absurdity and more like warning. It’s time to stop shouting about protein and start listening—to appetite, to reason, and maybe to the quiet voice reminding me that balance, not bulking, is the real art form.
