Your personalized daily protein target, based on real nutrition guidelines
💡 Why This Matters Protein needs vary a lot by body weight, activity level, and goal — a one-size-fits-all number isn't useful. Enter your details to get a target range based on established nutrition science.
Eating protein earlier in the day — especially at breakfast — helps stabilize blood sugar and can reduce cravings later on, since protein slows digestion and blunts the glucose spike that comes from carb-heavy meals eaten alone.
Adults can lose 3-8% of their muscle mass per decade after age 30, a process called sarcopenia — and it accelerates further after 60. Eating more protein than a younger adult would need is one of the most effective ways to help slow this down, alongside strength training.

Your protein target is calculated as grams per kilogram of body weight, adjusted by activity level, goal, age, and pregnancy/lactation status. General health guidelines start around 0.8 g/kg, while active individuals, muscle-building goals, weight-loss-while-preserving-muscle goals, and serious recomposition ("best shape of my life") push that range up to 1.6-2.4 g/kg. Note that gaining weight/bulking doesn't require more protein than lean muscle building — the difference between those two goals is calorie surplus, not protein grams. Adults 65+ get an upward adjustment regardless of activity level or goal, since research on age-related muscle loss (sarcopenia) generally supports higher protein intake for older adults. Pregnancy and lactation each add an estimated flat daily bonus, reflecting real increased protein needs during those stages.
The result is a daily gram target, shown as a range rather than one exact number, since individual needs vary even within the same activity/goal combination. Aim to land within the range consistently rather than hitting an exact number every single day.
This is a general nutrition guideline, not personalized medical advice. People with kidney conditions, certain metabolic conditions, or specific medical circumstances should get individualized protein guidance from a doctor or registered dietitian rather than relying on a general calculator.
Use your target as a daily guide when planning meals, and consider spreading it across multiple meals rather than one large serving. Pair with a food tracking app or a Water Needs and Macros calculator for a fuller picture of your daily nutrition.
Example: A 70 kg person who is moderately active and aiming for general health falls in the 1.2-1.6 g/kg range: 70 × 1.2 = 84g to 70 × 1.6 = 112g of protein per day.
It depends on your body weight, activity level, and goal. General health guidelines start around 0.8 grams per kilogram of body weight, while active individuals, those building muscle, or those losing weight while preserving muscle typically need 1.2 to 2.4 grams per kilogram.
For most healthy adults, higher protein intakes within these ranges are considered safe, but very high intakes over long periods should be discussed with a doctor, especially if you have kidney concerns or other health conditions.
Most guidelines are based on current body weight, since that reflects your body's actual current needs. If you're significantly overweight, some nutrition guidance suggests using a more moderate estimate rather than raw current weight — this calculator uses current weight for simplicity.
They're general reference estimates based on typical protein content per serving, not exact figures for a specific product or cut. A quick-reference line up top shows the gram-per-ounce (or per-cup, per-egg) math before the food list, so the numbers below make sense at a glance. Each line is a separate either/or option — pick one, not all of them combined — and amounts that would be unrealistic to eat from a single source (like several dozen eggs) are shown as a spread-across-the-day note instead of a literal count.
Not unhealthy, but different — dark meat chicken (thighs, wings) and red meat are both solid protein sources, but they run higher in saturated fat than lean chicken breast, which can affect LDL cholesterol. Many nutrition guidelines suggest leaning on lean cuts as your everyday default and treating higher-fat options as less frequent choices, rather than avoiding them entirely.
No — the protein target for both goals is similar. What actually differs is total calorie intake: bulking means eating in a calorie surplus, while lean muscle building typically means eating closer to maintenance calories. Protein needs don't change much between the two.
Yes — adults 65 and older generally need more protein per kilogram of body weight than younger adults at the same activity level, since research on age-related muscle loss (sarcopenia) supports higher intake to help preserve muscle mass. This calculator applies an upward adjustment for that age range.
Yes — both pregnancy and lactation meaningfully increase protein needs, and this calculator adds an estimated daily amount to reflect that. Because individual needs vary during these stages, always confirm your exact target with a doctor or midwife rather than relying on a general calculator alone.
