Example: Calculating Protein Needs for a Moderately Active Person

Let’s say Sarah is a 30-year-old female weighing 65 kg who exercises moderately 3–5 times per week. Her goal is to build muscle.

Weight: 65 kg
Activity Level: Moderate
Goal: Muscle Gain

After entering her details, the calculator determines her protein range to be around 1.5–2.0 g/kg, meaning she should consume roughly 98–130 grams of protein per day.

That’s equivalent to approximately:

6 large eggs
2 chicken breasts
2 cups of Greek yogurt

This personalized insight helps Sarah plan her meals and protein sources more effectively.
