Protein powder is the buzz word on social media, but is more really better? The data-driven truth and who needs how much

It’s 2025, and protein isn’t just a macronutrient; it’s a full-blown phenomenon sweeping social media, supermarket shelves, and dinner tables around the world. Americans in particular are obsessed: a whopping 61% boosted their protein intake in 2024, compared to just 48% in 2019. From TikTok trends like “200 grams of protein a day” to an explosion of protein-packed snack bars, pancake mixes, and even popcorn, everyone’s chasing that muscle-building magic.

From steak to shakes: How the protein craze took off

Protein’s popularity isn’t entirely new; it’s the only macronutrient never vilified in the shifting sands of diet culture. Since the 1860s - when German chemist Justus von Liebig pushed 'meat extract' as a protein shortcut - food companies have been innovating, from cheese byproduct 'whey' powder to modern bars and ready-to-drink shakes.

Today, Cargill’s 2025 Protein Profile shows 57% of consumers scan labels specifically for protein content, and over 75% insist that animal proteins (think beef, chicken, eggs) are vital for dinner.

Is there a dark side to all this protein?

While the “protein rules” mantra is hard to resist, doctors warn there can be too much of a good thing. Going far above recommended levels (think 200g-400g a day) can strain kidneys and liver, trigger dehydration, and - even though rare - potentially up your risk of heart disease if your protein comes from fatty red meats. The University of Missouri recently flagged that excessive protein can activate cellular pathways leading to cardiovascular trouble.


Experts agree: most healthy adults are fine staying within 0.8-1.6g/kg, and plant-based sources can be just as muscle-friendly without the scare.

Who benefits most?

Older people, especially post-menopausal women, may need more protein for bone and muscle health, but can usually get what they need from a balanced diet, no supplements required.

For athletes and fitness enthusiasts, protein powers recovery and performance, but more is not necessarily better: it’s important to balance intake with other nutrients, hydration, and activity.

The science behind the surge

Many influencers call for ultra-high protein goals, sometimes urging up to 2.2g/kg of body weight daily, nearly triple the basic recommendation. Social media fuels the fire, with 40% of non-professional athletes getting supplement advice from Instagram, TikTok, and Twitter - often from people with no nutrition credentials.

For most adults, the recommended daily protein intake is about 0.8 grams per kilogram of body weight, which means if you weigh 70kg, you’d need roughly 56g of protein each day. Older adults and people who are highly active or involved in sports may benefit from higher amounts, a bit more for pregnant or breastfeeding women.

Your protein should ideally come from a variety of sources like lean meats, dairy, eggs, beans, and nuts, spread evenly throughout meals to help your body absorb and use it efficiently. The recent surge in protein popularity is driven by evidence that moderate increases in protein keep you feeling fuller longer, support muscle growth and maintenance, and help with recovery, especially as people age.

However, science shows that eating more than about 1.6g/kg per day doesn't bring extra benefits and can even carry health risks if far in excess, especially from heavy red meat or supplements. Most people in developed countries easily meet these recommendations, so unless you have special needs or are very active, focus on consistent, balanced protein rather than chasing ultra-high trends.

Consumer impact: Snack, sip, repeat

Food companies are riding the wave. Brands like PepsiCo, Kraft Heinz, and Oscar Mayer are rolling out new high-protein offerings - from updated lunchables packs boasting 12g of protein per serving, to restaurant-quality cuts for at-home indulgence. Restaurants report a 10% jump in protein mentions on menus in the last year, and one in five spotlights protein in their dishes.
