Protein Calculator - Protein Requirements for the Body: Understanding How Much You Need

At, we understand the significance of protein as a macronutrient in promoting growth, repair, and maintenance of body tissues. But how do we determine our protein needs? Our Protein Calculator helps you calculate the optimal protein intake for various age groups and genders.

Protein Requirements by Age and Gender:

The protein requirements for the body vary depending on age, gender, and physical activity levels.

However, children, adolescents, pregnant or lactating women, and athletes may need more protein.

Children aged 1-3 years need about 13 grams of protein daily, while those aged 4-8 need about 19 grams. Adolescents aged 9-13 years require around 34 grams of protein daily, and those aged 14-18 need about 52 grams for boys and 46 grams for girls.

Adult men and women have similar protein requirements, with men needing around 56 grams per day and women needing about 46 grams. However, pregnant or lactating women may need more protein to support the growth and development of their babies.

If you are trying to lose weight or build muscle, you may need more protein than the average person. Protein can help you feel full longer, reduce cravings, and boost your metabolism. A protein calculator for weight loss or muscle gain can help determine how much protein you need to reach your goals.

To build muscle, you must consume more protein than your body breaks down during exercise. The general recommendation is to consume 1.6-2.2 grams of protein per kilogram of body weight per day. However, this may vary depending on your fitness level, training intensity, and other factors.
