The Protein Craze: Separating Science From Hype

Protein has become the superstar of the wellness world. Walk through any grocery store, and you’ll see “high protein” labels everywhere — from cereal and chips to pancake mix and ice cream. Even coffee chains like Starbucks now offer protein-packed drinks aimed at customers looking to boost their intake.

Social media influencers promote protein goals that can top 150 grams a day, while protein powders, bars and shakes have become billion-dollar businesses. But amid all the hype, many people are left wondering: How much protein do you actually need?

The answer depends on your age, activity level and overall health — but for most people, it’s probably less than the internet suggests.

"Protein is essential for nearly every function in the body. It helps build and repair muscles, supports the immune system, produces hormones and enzymes, and keeps skin, hair and organs healthy. Unlike carbohydrates and fat, the body does not store protein for long-term use, so it needs a regular daily supply through food," says Connie Weaver, a registered dietician at Lexington Health. 

For the average healthy adult, the Recommended Dietary Allowance (RDA) is:

0.36 grams of protein per pound of body weight per day

That means:

Some groups benefit from higher protein intake, including:

For active adults, experts often recommend somewhere between 0.54 to 0.9 grams of protein per pound of body weight per day, depending on training intensity and goals.

Older adults may also need more protein because muscle mass naturally declines with age. Recent guidance highlighted in the updated U.S. dietary recommendations suggests many adults over 60 may benefit from a higher intake than the traditional minimum recommendation.

Probably yes.

Research shows most Americans already meet or exceed the basic protein recommendation through normal eating patterns.

That means many people do not necessarily need a protein-spiked coffee in the morning, a protein bar in the afternoon and extra scoops of powder after dinner.

The recent protein craze has created the impression that more is always better, but nutrition experts say that’s not necessarily true. Eating excess protein does not automatically build more muscle — resistance training and overall lifestyle matter too.

Protein can absolutely be part of a healthy diet, but experts encourage focusing on the overall “protein package” rather than simply chasing grams.

Good protein sources include:

Many highly marketed protein products can also contain added sugar, sodium or saturated fat. A protein cookie is still a cookie.

Weaver say, "For most healthy people, moderately high protein intake is not dangerous. But consistently consuming extremely high amounts may not provide additional benefits and could crowd out other important nutrients, such as fiber-rich fruits, vegetables, and whole grains."

People with kidney disease or certain medical conditions should talk with their doctor or a registered dietitian before dramatically increasing protein intake.

Protein deserves its healthy reputation, but most people do not need to obsess over hitting massive daily protein targets.

A balanced approach usually works best:

• Don’t fall for every “high protein” marketing trend.
