If your BMI falls between 18.5 and 24.9, it indicates you are within the healthy weight range. If your BMI is greater than 25, then you fall into the overweight category. As weight increases above a healthy range, the increased body fat levels are associated with a higher risk of developing health problems such as high blood pressure, high LDL cholesterol levels, type 2 diabetes, coronary heart disease, stroke and some cancers. A BMI below 18.5 is classified as underweight and if the low body weight is a result of restricted food intake, an inadequate nutrient intake is probable.
Is it always accurate? It’s important to understand that BMI is only a guide for healthy weight ranges and health risk in adults – it doesn’t always tell the whole story. People who have higher proportions of muscle, such as athletes and body builders, may be incorrectly classified as overweight. Similarly, people with small frames and lower amounts of muscle mass, including the elderly and some ethnic groups, may be classified as being a healthy weight, despite carrying excess weight for their body type. BMI can be a much better indicator of health status when paired with the Waist Hip Ratio, which considers where the body fat is distributed.
