The calculator uses the protein requirements formula:
Where:
Explanation: The equation accounts for baseline protein needs (0.8g per kg of body weight) plus additional requirements for growth in younger ages and muscle maintenance in older adults.
Details: Adequate protein intake is crucial for maintaining muscle mass, supporting immune function, promoting satiety, and ensuring proper growth and development in children and adolescents.
Tips: Enter weight in kilograms and select the appropriate age group. The calculator will provide an estimate of daily protein requirements in grams.
Q1: Are these requirements the same for everyone?
A: No, protein needs can vary based on activity level, health status, and specific conditions. Athletes and pregnant women may need more protein.
Q2: What if I'm very active or an athlete?
A: Active individuals may need 1.2-2.0g of protein per kg of body weight, depending on training intensity and goals.
Q3: Can you get too much protein?
A: Excessive protein intake may strain kidneys in individuals with pre-existing kidney conditions, but is generally safe for healthy people.
Q4: What are good sources of protein?
A: Lean meats, fish, eggs, dairy products, legumes, nuts, and soy products are all excellent protein sources.
Q5: Should protein intake be adjusted for weight loss?
A: Higher protein intake during weight loss can help preserve muscle mass and increase satiety, often recommending 1.2-1.6g per kg of body weight.
