You’ve likely encountered numerous diets promising effortless weight loss, muscle building, joint protection, or even Alzheimer’s prevention. Often, these claims are too good to be true, and high-protein diets are a prime example of this phenomenon, whether through supplements or increased portions within a balanced diet. But How Much Protein Should You Be Eating A Day to reap the benefits without the drawbacks?
Understanding Your Protein Needs
Protein is fundamental to life. It acts as a building block for every cell and plays a vital role in biochemical functions, especially in growth, development, and tissue repair. As one of the three macronutrients (along with carbohydrates and fats), adequate protein intake is crucial. It prevents malnutrition and can preserve muscle mass and strength as we age. Some suggest high-protein diets can boost metabolism and aid weight loss, although results vary.

Recommended Daily Intake of Protein
Determining the ideal daily protein intake can be tricky. Common recommendations include:
- General Guidelines: 56 grams/day for men, 46 grams/day for women. This amount can be obtained from a serving of low-fat Greek yogurt, 4 ounces of lean chicken breast, and cereal with skim milk.
- Weight-Based RDA: 0.8 grams per kilogram of body weight. A 140-pound (64 kg) person would need about 51 grams daily. (Pounds to kilograms: divide by 2.2). Active individuals, particularly those aiming to build muscle, might need more.
- Percentage of Calories: For active adults, approximately 10% of daily calories should come from protein.
- Protein Type Focus: Prioritize protein type over quantity, moderating red meat and increasing sources like salmon, yogurt, or beans.
Some experts suggest doubling the standard recommendations, while others believe the average American diet already includes too much protein.
The Potential Risks of Excessive Protein Consumption
The answer to the question, “How much protein should you be eating a day?” also depends on potential risks. Eating too much protein can have negative consequences. Very high protein diets have been linked to a higher risk of kidney stones. Moreover, a diet rich in red meat and saturated fat may increase the risk of heart disease and colon cancer, while plant-based protein diets may not carry the same risks.
Identifying “Too Much” Protein
Defining “too much” protein is challenging due to varying expert opinions and individual factors. For most healthy individuals (excluding elite athletes or bodybuilders), limiting total protein intake to no more than 2 grams per kilogram of ideal body weight is advisable. For a 140-pound person with a normal BMI, this translates to approximately 125 grams per day.
Building a Healthy High-Protein Diet
If you want to maintain a high protein diet, the details matter. Here’s how to ensure you’re getting the protein you need without compromising your health:
- Consult Your Doctor: Rule out any health conditions (like kidney disease) that might make a high-protein diet risky.
- Choose Healthy Sources: Opt for low-fat dairy, fish, nuts, beans, lean chicken, and turkey. Avoid highly processed carbohydrates and saturated fat.
- Distribute Intake: Spread your protein consumption evenly throughout the day.
- Balance Your Diet: Include plenty of vegetables, fruits, and fiber. Consider the Mediterranean or DASH diets as starting points.
