How Much Protein Do I Need — For Me?

Get your personalized daily protein target and find out exactly how many eggs to eat — based on your weight, goal, and activity level.

The government's recommended 0.8g/kg protein guideline was designed to prevent deficiency — not to optimize health, body composition, or performance. For the vast majority of active adults, this number is too low. Yet generic protein calculators online give you the same answer regardless of whether you're trying to lose fat, build muscle, or simply stay healthy at 65.

📊 Research consensus: Active adults benefit from 1.2–2.2g of protein per kilogram of body weight daily. That's a 3x range — which is why "how much protein do I need" has no single answer, only your answer.

This calculator applies the protein multipliers used in sports nutrition research, adjusted for your specific goal, activity level, and age. It also translates your target into a practical egg recommendation — including how many eggs cover your needs and how much protein you'll still need from other sources.

How Much Protein Do I Need Per Day? The Complete 2026 Guide

The question sounds simple, but it has generated decades of research, multiple competing guidelines, and significant confusion. Here is what the current evidence actually says — stripped of supplement company marketing and oversimplified rules of thumb.

Goal / Population Protein per kg body weight For a 154lb (70kg) person
Government RDA (minimum to prevent deficiency)0.8g/kg56g/day
Sedentary adult, general health1.0–1.2g/kg70–84g/day
Active adult, general fitness1.2–1.6g/kg84–112g/day
Fat loss (preserve lean mass)1.6–2.4g/kg112–168g/day
Muscle building / hypertrophy1.6–2.2g/kg112–154g/day
Endurance / athletic performance1.4–1.7g/kg98–119g/day
Adults 65+ (any activity level)1.0–1.6g/kg70–112g/day

Why the Government RDA Is Too Low for Most People

The 0.8g/kg RDA was established to meet the needs of 97.5% of sedentary adults — it is a floor, not a target. A 2017 meta-analysis of 49 studies in the British Journal of Sports Medicine found that for people engaged in resistance training, protein intakes well above the RDA were consistently associated with greater muscle gains. For fat loss, higher protein preserves muscle tissue while the body is in a caloric deficit — with research supporting intakes up to 2.4g/kg during aggressive cuts.

Protein During Fat Loss: Why You Need More, Not Less

Many people intuitively reduce protein when dieting. The research says the opposite. When calories are restricted, the body becomes more likely to break down muscle tissue for energy. Higher protein intake during a deficit signals the body to preserve that muscle. Studies consistently show that dieters consuming 1.6–2.4g/kg protein lose more fat and retain more muscle than those eating the standard RDA — even in a caloric deficit.

⚠️ The "protein is bad for kidneys" myth: In healthy adults with normal kidney function, high protein diets have not been shown to cause kidney damage. This concern applies specifically to people who already have chronic kidney disease, for whom protein restriction is appropriate. If you have no kidney disease, dietary protein at levels recommended for athletes is considered safe by current research consensus.

How Many Eggs Per Day Is Safe?

Current evidence from large prospective studies and meta-analyses suggests 1–3 eggs per day is safe for most healthy adults. A 2020 meta-analysis in the BMJ examining over 1.7 million participants found no significant association between consuming up to 1 egg per day and cardiovascular risk in the general population. For people with type 2 diabetes or existing cardiovascular disease, limiting to 1 egg per day and consulting a physician remains the conservative recommendation.

Each large egg provides 6.3g of high-quality, complete protein containing all essential amino acids. The yolk contains most of the micronutrients — including choline (critical for brain function), vitamins D, A, E, K, B12, and selenium. Discarding yolks to save cholesterol means losing the majority of the egg's nutritional value for a modest calorie reduction.

Frequently Asked Questions

How much protein do I need per day?
The government RDA is 0.8g per kilogram of body weight — roughly 56g/day for a 154lb person. However, research consistently shows active adults benefit from 1.2–2.2g/kg depending on goal. Use the calculator above to get your personalized target based on your weight, goal, and activity level.
How many eggs can I eat per day?
For most healthy adults, 1–3 eggs per day is well-supported by current evidence. A 2020 BMJ meta-analysis of 1.7 million people found no significant cardiovascular risk from up to 1 egg/day in healthy individuals, and multiple studies show 2–3 eggs/day is safe for those without diabetes or heart disease. Each large egg provides approximately 6.3g of complete protein.
Is the protein in egg whites or egg yolks?
Both. A large egg contains approximately 3.6g of protein in the white and 2.7g in the yolk. The yolk also contains all fat-soluble vitamins (A, D, E, K), choline, and most micronutrients. Eating whole eggs is nutritionally superior to whites alone.
Can I hit my protein goals with eggs alone?
Not practically. To get 150g of protein from whole eggs alone, you'd need roughly 24 eggs per day — far beyond what's advisable. Eggs work best as one anchor protein source: 2–3 at breakfast provides 12–18g, with the remainder from chicken, fish, Greek yogurt, legumes, or protein supplements.
Does cooking method affect egg protein?
Yes — cooking increases protein bioavailability. Research shows cooked eggs provide ~91% protein digestibility versus ~51% for raw eggs. Heat denatures proteins, making them easier for digestive enzymes to break down. All cooking methods (boiled, scrambled, poached, fried) retain essentially the same gram count of protein.
Do protein needs change as I get older?
Yes, significantly. After 65, the body becomes less efficient at using dietary protein to build and maintain muscle — called anabolic resistance. Research recommends adults over 65 consume 1.0–1.2g/kg minimum even if sedentary, and 1.2–1.6g/kg if active. This is 25–50% above the standard adult RDA.
How much protein do I need to build muscle?
The research consensus for muscle hypertrophy is 1.6–2.2g of protein per kilogram of body weight per day, consumed across 3–5 meals. A 2017 meta-analysis of 49 studies found that intakes above 1.62g/kg/day did not produce additional gains on average. Timing matters: consuming 20–40g within 2 hours of resistance training maximizes muscle protein synthesis.
