Protein Intake Calculator

Find out exactly how much protein you need every day to hit your fitness goals, with guidance from , personal fitness & nutrition coach.

Calculate Your Protein Intake

Quick Reference

  • General health (sedentary): 0.8–1.0 g/kg body weight
  • Weight loss: 1.6–2.2 g/kg to preserve muscle in a deficit
  • Muscle gain: 1.8–2.5 g/kg depending on training experience
  • Athletic performance: 2.0–3.1 g/kg
  • Spread intake across 4–5 meals of 25–40g each for best results

How to Use This Protein Intake Calculator

  1. 1

    Enter your details

    Add your gender, age, height and body weight so the calculator can personalize your result.

  2. 2

    Pick your activity level

    Choose how often you train each week, from sedentary to daily intense training.

  3. 3

    Choose your goal

    Select whether you want to maintain weight, lose fat or build muscle — protein needs shift with each goal.

  4. 4

    Get your daily target

    You'll get a gram range, a per-meal breakdown, and an estimated daily calorie need.

How Much Protein Do You Need Per Day?

Daily protein needs scale with body weight, activity level and goal. The table below shows commonly recommended ranges in grams of protein per kilogram of body weight.

Goal / activityProtein range
Sedentary / general health0.8 – 1.0 g/kg
Light activity1.2 – 1.4 g/kg
Weight loss (preserve muscle)1.6 – 2.2 g/kg
Muscle gain1.7 – 2.2 g/kg
Endurance / athlete training1.8 – 2.2 g/kg

Protein Intake for Weight Loss

When you eat fewer calories than you burn, your body can break down muscle for energy alongside fat. A higher protein intake — typically 1.6g to 2.4g per kilogram of body weight — helps preserve lean muscle during a cut, keeps hunger in check thanks to protein's satiety effect, and slightly raises the number of calories burned digesting food.

Protein Intake for Muscle Gain

Building muscle requires a calorie surplus, consistent resistance training, and enough protein to fuel muscle repair — generally 1.6g to 2.2g per kilogram of body weight per day. Spreading protein evenly across 3–4 meals, rather than loading it into one meal, gives your body a steady supply of amino acids for muscle protein synthesis throughout the day.

Protein Intake for Women

Protein needs for women follow the same weight-based ranges as men, with a few life stages that call for extra intake. Pregnancy and breastfeeding both raise protein needs to support the baby's growth, while adequate protein after menopause helps offset the natural decline in muscle and bone density.

Life stageRecommended intake
General adult woman1.2 – 1.6 g/kg
Pregnancy+ ~25 g/day above baseline
Breastfeeding+ ~25 g/day above baseline
Post-menopause1.4 – 1.8 g/kg (supports bone & muscle)

General guidance only — pregnant or breastfeeding women should confirm intake with their doctor or midwife.

Protein Intake on GLP-1 Medications (Ozempic, Wegovy, Mounjaro)

GLP-1 medications suppress appetite, so total food intake — and with it, protein intake — often drops sharply. Because a large share of weight lost on these medications can come from muscle if protein is neglected, many prescribers now recommend prioritizing protein-rich foods first at every meal and aiming for the higher end of the standard range (around 1.2g–1.6g per kilogram of body weight, or more if you also strength train).

  • Eat protein first, before carbs or vegetables, at each meal.
  • Favor high-protein, low-volume foods (eggs, Greek yogurt, whey, paneer) since appetite and portion sizes are reduced.
  • Pair with light resistance training where possible to help protect muscle mass.

This is general information, not medical advice. Always follow the guidance of the doctor managing your prescription.

Frequently Asked Questions

Most adults need between 0.8g and 2.2g of protein per kilogram of body weight per day, depending on activity level and goals. Sedentary adults need less, while those building muscle or in a calorie deficit need more to preserve lean mass.
