What To Do With My BMI Result

Underweight (BMI below 18.5)

You may be undernourished or not getting enough calories, protein, or essential nutrients. Eat nutrient-rich, high-calorie foods like nuts, avocados, eggs, milk, and whole grains. Add healthy snacks between meals. Focus on strength-building exercises to increase muscle mass.

Normal Weight (BMI 18.5 – 24.9)

Your weight is in a healthy range for your height. Maintain a balanced diet with fruits, vegetables, proteins, and whole grains. Exercise at least 30 minutes daily (walking, jogging, yoga, etc.).

Overweight (BMI 25 – 29.9)

You may be carrying extra body fat that can increase your risk for heart disease, diabetes, and other conditions. Focus on portion control and reduce processed or sugary foods. Exercise regularly — aim for at least 150 minutes of physical activity per week. Drink plenty of water and get enough sleep.

Healthy Ways To Improve BMI And Decrease Obesity Risk

Eat Balanced Diet

Include a mix of fruits, vegetables, lean proteins, whole grains, and healthy fats. Avoid skipping meals and try to eat at regular times to maintain energy and metabolism.

Stay Hydrated

Drink at least 6–8 glasses of water daily. Staying hydrated helps control appetite, improves digestion, and supports fat metabolism.

Exercise Regularly

Engage in at least 150 minutes of moderate physical activity per week — like walking, cycling, or swimming. Add some strength training to build lean muscle, which helps burn calories even at rest.

Get Enough Sleep

Poor sleep can disrupt hormones that control hunger and weight. Aim for 7–8 hours of quality sleep every night to help maintain a healthy BMI.

Manage Stress

Stress can lead to overeating or unhealthy habits. Try meditation, yoga, or deep breathing exercises to keep your mind and body balanced.

Seek Professional Advice

If your BMI is too low or too high, consult a doctor or dietitian for personalized guidance. They can help you create a healthy plan based on your body type, age, and activity level.

BMI Obesity vs Health

A study published by Journal of the American Medical Association (JAMA) in 2005 showed that overweight people had a death rate similar to normal weight people as defined by BMI, while underweight and obese people had a higher death rate.

A study published by The Lancet in 2009 involving 900,000 adults showed that overweight and underweight people both had a mortality rate higher than normal weight people as defined by BMI. The optimal BMI was found to be in the range of 22.5–25. The average BMI of athletes is 22.4 for women and 23.6 for men.

High BMI is associated with type 2 diabetes only in people with high serum gamma-glutamyl transpeptidase.
