Body Mass Index (BMI) is an important measure of body fat because it can help to identify whether an individual is underweight, normal weight, overweight, or obese.
This information can be used as a starting point for a conversation about a person’s overall health and the potential risks associated with being underweight or overweight.

BMI Categories:
Underweight = <18.5
Normal weight = 18.5–24.9
Overweight = 25–29.9
Obesity = BMI of 30 or greater
Being underweight or overweight can have negative effects on health. Underweight individuals may have a higher risk of nutrient deficiencies, weakened immune systems, and osteoporosis.
On the other hand, being overweight or obese can increase the risk of various health conditions such as heart disease, type 2 diabetes, high blood pressure, stroke, and certain cancers.
IF YOU ARE UNDERWEIGHT
If you are underweight, there are a few things that you can do to gain weight:
- Eat more calories: Make sure to eat enough to meet your calorie needs. You may need to eat more than the average person to gain weight.
- Eat nutrient-dense foods: Focus on eating foods that are high in nutrients, such as lean proteins, healthy fats, and complex carbohydrates.
- Eat more frequently: Eating smaller, more frequent meals throughout the day can help increase calorie intake.
- Incorporate weightlifting and strength training exercises: Building muscle can help increase weight.
- Consult a healthcare professional: A healthcare professional can provide personalized advice and guidance on how to gain weight in a healthy way.
It is important to note that underweight can be caused by underlying medical conditions or eating disorders, so it is important to consult with a healthcare professional before making any changes to your diet or exercise routine.
IF YOU ARE OVERWEIGHT
If you are overweight, there are a few things that you can do to lose weight:
- Eat a healthy diet: Focus on eating nutrient-dense foods such as fruits, vegetables, lean proteins, and whole grains. Avoid processed foods, sugary drinks, and excessive amounts of saturated and trans fats.
- Get regular exercise: Aim for at least 30 minutes of moderate-intensity exercise, such as brisk walking, cycling or swimming, most days of the week. Resistance training such as weightlifting can also be beneficial for weight loss and overall health.
- Create a calorie deficit: To lose weight, you need to burn more calories than you consume. You can do this by eating fewer calories, increasing your physical activity, or a combination of both.
- Track your progress: Keep track of your weight and measurements to monitor your progress and make adjustments as needed.
- Consult a healthcare professional: A healthcare professional can provide personalized advice and guidance on how to lose weight in a healthy way, and rule out any underlying medical conditions that may be causing weight gain.
It is important to note that losing weight should be done in a healthy way, and a slow and steady approach is often more sustainable in the long term. Crash diets and extreme measures can be harmful and lead to weight regain.
Association between BMI and Risk of Type 2 Diabetes:
- Higher BMI is associated with an increased risk of developing type 2 diabetes. The risk is progressive and increases with higher BMI categories.
- Multiple studies have demonstrated an exponential relationship between BMI and the risk of type 2 diabetes, with each increment in BMI associated with a higher risk.
- The risk of type 2 diabetes is influenced not only by absolute BMI but also by the distribution of body fat. Abdominal obesity, indicated by increased waist circumference or waist-to-hip ratio, is particularly associated with an increased risk of type 2 diabetes.
