Most people eat twice the protein they actually need

You've probably heard it by now: protein is the magic ingredient for building muscle, losing weight, fixing your metabolism. Influencers swear by it. Athletes live on it. Your gym buddy won't stop talking about it. But here's what the research actually shows — most of us are already eating far more protein than our bodies know what to do with.

Marc O'Meara, a senior nutritionist at Brigham and Women's Hospital, has spent years watching people chase protein targets that don't exist. The math is surprisingly simple. Take your body weight in pounds and multiply it by 0.36 to 0.45. That's your daily protein goal in grams. A 110-pound woman needs around 45 grams. A 180-pound man needs roughly 65 to 81 grams. In practical terms: a palm-sized portion of chicken or fish at each meal (20–25 grams), plus an egg and a light snack, gets most people there. Done.

The cost of too much protein

Protein itself isn't the problem. The problem is that more isn't better. Your kidneys have to process the excess nitrogen from extra protein, and they're not designed for a constant overload. Beyond that, high-protein products tend to be calorie-dense — protein packs about six times the calories per volume compared to vegetables. So the person eating 150 grams of protein daily while thinking they're optimizing their body is often just eating more calories than they burn, which leads to the exact opposite of their goal.

There are nuances worth knowing. Athletes with serious training loads do need more — up to 50 percent above the baseline. Pregnant women, breastfeeding mothers, and older adults need about 25 percent more than the average person. But for the desk worker, the casual gym-goer, the person just trying to feel better — the baseline formula works.

Where your protein comes from matters more than how much you're eating. Plant-based proteins from beans, nuts, and legumes show stronger links to lower chronic disease risk than animal proteins. They're also gentler on your kidneys. Meanwhile, processed protein bars and shakes often hide added sugars and ingredients that undermine whatever benefit you're chasing.

The practical shift is small but real: eat some protein with every meal, yes. But lead with vegetables, then add your protein, then carbs last. This order actually helps regulate blood sugar better than protein alone ever could. And skip the sugary desserts late at night — that's when protein's blood sugar-regulating effects have worn off anyway.

The high-protein diet trend isn't going anywhere, and that's fine. But the gap between what influencers are selling and what your body actually needs is wider than most people realize. The win isn't in chasing more protein. It's in eating the right amount of the right kind, and letting your body do what it's designed to do.
