Protein Intake Calculator
Protein is an essential nutrient in muscles, organs, enzymes, and immune components. Daily needs vary with body weight, activity, and weight goals.
The DiyetisyenPRO protein calculator estimates daily grams from your weight, activity multiplier, and goal adjustment. Results also show approximate calories from protein, per-meal split, a flexible target range, and sample food equivalents.
How Is Protein Need Calculated?
The base formula is weight (kg) × activity factor × goal factor. Activity factors run from 1.0 g/kg for sedentary lifestyles up to 1.8 g/kg for very heavy training. Goal factors are 1.20 for weight loss, 1.10 for weight gain, and 1.00 for maintenance.
Activity Multipliers Used
- Sedentary: 1.0 g/kg — little or no exercise.
- Lightly active: 1.2 g/kg — exercise 1–3 days per week.
- Moderately active: 1.4 g/kg — exercise 3–5 days per week.
- Very active: 1.6 g/kg — exercise 6–7 days per week.
- Extra active: 1.8 g/kg — twice-daily training.
Protein Food Sources
Eggs, dairy, fish, poultry, and lean meat are animal sources; lentils, chickpeas, beans, soy, nuts, and seeds are plant sources. Mixing sources supports vitamins, minerals, and fiber alongside protein.
How to Use Your Result
Use the calculated amount as a starting point for daily planning. Spread intake across meals and consider total energy intake. If health status, body composition, or performance goals need a tailored plan, work with a registered dietitian.
Frequently asked questions
This tool multiplies body weight by an activity coefficient from 1.0–1.8 g/kg. For weight loss the result is increased by 20%; for weight gain by 10%.
Adequate protein may help preserve lean mass and support fullness during a calorie deficit. Individual needs vary with total energy intake, exercise, and health status.
Generally yes. As training frequency and intensity rise, protein needs for repair and adaptation often increase. The tool reflects this via activity multipliers.
Spreading intake across meals and snacks is usually more practical than one large dose. Per-meal targets depend on total need and your eating pattern.
Legumes, soy, nuts, seeds, and whole grains provide protein. Combining varied sources through the day supports amino acid diversity.
No. Results are general estimates. People with kidney, liver, or metabolic conditions, pregnancy, breastfeeding, or elite training should consult a clinician for a personal plan.
