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.
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.

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/kg | 56g/day |
| Sedentary adult, general health | 1.0–1.2g/kg | 70–84g/day |
| Active adult, general fitness | 1.2–1.6g/kg | 84–112g/day |
| Fat loss (preserve lean mass) | 1.6–2.4g/kg | 112–168g/day |
| Muscle building / hypertrophy | 1.6–2.2g/kg | 112–154g/day |
| Endurance / athletic performance | 1.4–1.7g/kg | 98–119g/day |
| Adults 65+ (any activity level) | 1.0–1.6g/kg | 70–112g/day |
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.
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.
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.
