If your BMI is less than 18.5, it's a sign you are underweight. Being below your normal weight range can lead to a weaker immune system, brittle bones and can increase fatigue. You are likely to have nutritional deficiencies. Underweight women may also face fertility problems. Ensure that you eat right and seek an expert's help to gain weight in a safe way.

Healthy or normal weight

Has your BMI figured between 18.5 to 24.9 marks? You have a healthy weight. It is a good sign as healthy weight is linked with a lower risk of health problems. You should focus on maintaining the weight by consuming nutritious foods, engaging in regular physical activity, regularising sleep patterns and reducing stress levels.


A BMI between 25 and 29.9 is a clear indication that you are overweight. It is an alarm you must take seriously as it increases your risk of lifestyle diseases such as type 2 diabetes, hypertension, osteoarthritis, heart problems and more. Seek an expert's help to control your diet and plan a regular exercise regime.


If your BMI is over 30, you need to watch out! Obesity signals excessive fat accumulation which contributes to a high risk of life-threatening diseases. Unhealthy eating habits, lack of physical activity, an underlying disease such as thyroid or other factors may be responsible for obesity. You must reach out for professional advice on managing your weight naturally with a balanced diet and physical activity.
