10% Optimal Target160.1 lbs (-17.9 lbs)Major lipid & cardiac benefit
Target to Normal (24.9)154.3 lbs (-23.6 lbs)Reaches healthy BMI
Clinical Interpretation:

Your calculated BMI is between 25.0 and 29.9 kg/m², placing you in the overweight category. Modest lifestyle modifications and a 5% weight loss can significantly improve insulin sensitivity and lipid profiles.

WHO Adult Body Mass Index (BMI) Classifications

WHO & CDC Standard
ClassificationBMI (kg/m²)Associated Health Risk
Underweight
< 18.5 kg/m²Increased risk of nutritional deficiency and osteoporosis.
Normal / Healthy Weight
18.5 – 24.9 kg/m²Lowest statistical risk of chronic metabolic and cardiovascular disease.
Overweight
25.0 – 29.9 kg/m²Moderate risk. 5%–10% weight loss yields notable cardiovascular benefits.
Obesity Class I
30.0 – 34.9 kg/m²Elevated risk of hypertension, dyslipidemia, and type 2 diabetes.
Obesity Class II
35.0 – 39.9 kg/m²High risk of metabolic syndrome, sleep apnea, and osteoarthritis.
Obesity Class III (Severe)
≥ 40.0 kg/m²Very high risk. Multidisciplinary medical or bariatric evaluation advised.

Understanding Overweight Classifications & Metabolic Health

Body mass index serves as a population-level screening metric to assess adiposity and long-term health risks. Below is an exhaustive clinical guide detailing epidemiological definitions, cardiovascular mechanisms, and evidence-based reduction milestones.

Epidemiological Definitions of Overweight and Obesity

According to the World Health Organization (WHO) and National Health and Nutrition Examination Survey (NHANES) epidemiological research (Must A, Dallal GE, Dietz WH - Reference Data for Obesity), overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health:

Normal Range (18.5 – 24.9):

Associated with optimal physiological lipid levels, low insulin resistance, and baseline longevity.

Overweight (25.0 – 29.9):

Represents an early increase in adipose tissue mass. Early interventions prevent progression to clinical obesity.

Obesity Classes (≥ 30.0):

Subdivided into Class I (30–34.9), Class II (35–39.9), and Class III (≥ 40) based on progressive multi-organ disease risk.
