What to do with your result?
Your BMI is in the normal range. The goal is to maintain it through a balanced diet and regular physical activity. Nutrya helps you track your daily caloric intake to stay in this zone.
An overweight BMI indicates a potential excess of body fat. A moderate caloric deficit of 300-500 kcal/day allows a loss of 0.3-0.5 kg/week without frustration. Nutrya automatically calculates your calorie goal.
A BMI below normal may indicate underweight. Gradually increasing caloric intake with nutritious foods is the priority. Nutrya helps you reach your calorie and protein targets.
A BMI in the obesity range requires appropriate medical follow-up. Nutritionally, the most effective approach is a gradual and sustainable reduction — not a severe diet. Nutrya supports you with realistic goals.
BMI Limitations
BMI is a screening indicator, not a diagnosis. It does not distinguish between muscle mass and fat mass: a very muscular athlete may have a high BMI without excess fat. Similarly, an older person may have a normal BMI but excess abdominal fat. Use it as a starting point, not as an absolute truth.
