How much protein do you really need? Experts warn we’re eating too much

Protein diets are very popular now, thanks to influencers, athletes, and many protein shakes, bars, and snacks. Many people believe more protein automatically gives better health, stronger muscles, weight loss, and steady energy.

Marc O’Meara, senior nutritionist at Brigham and Women’s Outpatient Department, says this trend has gone too far. He told a Harvard publication that while protein is essential, too much can quietly harm the body, as per the TOI report.

How much protein you really need

For most adults, daily protein needs are much lower than social media numbers. A simple formula: body weight in pounds × 0.36–0.45 = grams of protein per day. Example: a 110-pound woman needs about 45 grams per day. Common online advice of 150 grams or more is way too high.

Simple ways to meet protein needs

A palm-sized serving of chicken or fish = 20–25 grams of protein. Two such portions per day plus an egg or small snack easily meets protein needs, as stated by TOI. Plant proteins and dairy can also give enough protein if eaten consistently. Doubling or tripling protein can strain kidneys and doesn’t help health or fitness.

Athletes and very active people need about 50% more than normal. Pregnant or breastfeeding women need roughly 1.25× the standard amount; twins may require up to 100 grams/day. Adults over 65 benefit from slightly more protein to maintain muscle and bone health, but exercise is more important than just extra protein.

Protein makes you feel full and slows sugar absorption, giving longer-lasting energy. Social media links protein with muscles and fitness, but exaggerated recommendations of 150–200 grams/day are unnecessary and risky.

Risks of too much protein

Can stress kidneys because they process protein metabolism byproducts. Protein-heavy meals are calorie-dense; too much can lead to stalled weight loss or fat gain.

Both are good, but plant protein may be healthier long-term. Studies (Nurses’ Health Study) show people eating more beans, nuts, and dairy have lower chronic disease risk, as reported by TOI. Plant proteins have fiber, vitamins, and minerals; animal proteins may lack these. Plant proteins may be gentler on kidneys. Protein shakes/bars are okay occasionally if made from real food.

Include protein in every meal or snack to stay full and keep blood sugar steady. Eat order: vegetables first, protein, carbs/dessert last. Eating dessert right after protein is better than hours later to avoid sugar spikes and fat storage.

Protein is essential, but extreme high-protein diets are unnecessary. Most adults can meet needs with simple portions of meat, fish, eggs, beans, or dairy. No need for extreme targets or highly processed protein foods.
