Take the Guesswork Out of Protein Intake with Our Science-Backed Calculator
Ever wondered how much protein you really need for muscle growth, maintenance, or weight loss? Our Optimal Protein Intake Calculator is here to provide personalized, science-backed recommendations based on the latest research from the International Society of Sports Nutrition (ISSN).
Why Protein Intake Matters More Than Ever
Protein plays a crucial role in muscle growth and muscle maintenance. Whether you're aiming to build muscle, lose weight, or maintain your current physique, understanding your optimal protein intake is essential.
However, figuring out the right amount can be confusing. That's where our calculator comes in—it takes the guesswork out of the equation by providing tailored recommendations based on your unique profile.
Introducing the Optimal Protein Intake Calculator
Our calculator considers multiple factors to deliver precise protein intake recommendations:
- Age
- Weight and Height
- Sex
- Activity Level
- Body Fat Percentage
- Fitness Goals
- Diet Type (Omnivore, Vegetarian, Vegan)
Key Features:
- Personalized Results: Get recommendations customized to your individual needs.
- Science-Backed: Built on the latest ISSN research for accurate and reliable guidance.
- Dietary Adjustments: Accounts for different dietary preferences and protein bioavailability.
- User-Friendly Interface: Intuitive design makes it easy for anyone to use.
How It Works
- Enter Your Details: Provide information about yourself, including age, weight, height, sex, activity level, body fat percentage, fitness goals, and diet type.
- Get Your Results: Receive your optimal daily protein intake, along with a breakdown per meal.
- Understand the Science: Explore a detailed explanation of how your results were calculated, grounded in the latest research.
Example Calculation:
User Profile:
- Age: 30
- Weight: 70 kg
- Body Fat Percentage: 15%
- Activity Level: Strength Training
- Diet Type: Vegetarian
- Fitness Goal: Muscle Growth
Recommended Daily Protein Intake: 128–176 grams per day.
Per Meal Breakdown (4 meals): Approximately 32–44 grams of protein per meal.
Protein Needs Based on Activity Level
Understanding your protein needs is crucial for achieving your health and fitness goals. The table below outlines the recommended daily protein intake based on different activity levels, according to the latest guidelines from the International Society of Sports Nutrition (ISSN).
| Activity Level | Protein Intake | Description |
|---|---|---|
| Sedentary | 0.8 g/kg/day | Minimal physical activity; meets the Recommended Dietary Allowance (RDA) |
| Recreational Exercise | 1.0 – 1.4 g/kg/day | Light exercise a few times per week |
| Endurance Training | 1.4 – 2.0 g/kg/day | Regular endurance training (e.g., running, cycling) |
| Strength Training | 1.6 – 2.2 g/kg/day | Regular resistance training focused on muscle gain |
| High-Intensity Training | 1.6 – 2.2 g/kg/day | High-volume or intense training sessions |
| Weight Loss | 2.3 – 3.1 g/kg LBM/day† | Aimed at fat loss while preserving muscle mass; protein needs are higher due to caloric restriction |
† For weight loss, protein needs are calculated per kilogram of lean body mass (LBM), not total body weight.
Backed by Science
Our calculator is grounded in the most recent research from the ISSN, ensuring you receive credible and up-to-date recommendations. This includes adjustments for:
- Age: Increased protein needs for individuals over 65 to counteract anabolic resistance.
- Diet Type: Adjustments for vegetarians and vegans due to differences in protein bioavailability.
- Activity Level: Higher protein needs for more active individuals to support muscle repair and growth.
- Weight Loss Goals: Elevated protein intake to preserve muscle mass during caloric deficits, calculated based on lean body mass.
Clarification on Weight Loss Protein Needs
During weight loss, protein requirements are higher to prevent muscle loss while reducing body fat. The ISSN recommends:
- Protein Intake: 2.3 – 3.1 g/kg lean body mass per day.
- Calculating Lean Body Mass (LBM):
[ \text{LBM} = \text{Total Body Weight} \times (1 - \frac{\text{Body Fat Percentage}}{100}) ]
Example Calculation for Weight Loss:
User Profile:
- Weight: 80 kg
- Body Fat Percentage: 25%
- Lean Body Mass: 80 kg × (1 - 0.25) = 60 kg
Recommended Protein Intake:
- Minimum: 60 kg × 2.3 g/kg/day = 138 grams per day
- Maximum: 60 kg × 3.1 g/kg/day = 186 grams per day

For Omnivores:
- Chicken Breast: 31g protein per 100g
- Lean Beef: 29g protein per 100g
- Greek Yogurt: 17g protein per cup
- Eggs: 6g protein per large egg
For Vegetarians:
