What This Means
Obese range: significantly elevated health risks
A BMI of 30 or above is classified as obese by the World Health Organization. This range is associated with substantially higher risk of cardiovascular disease, type 2 diabetes, hypertension, sleep apnea, and certain cancers. Excess weight increases chronic inflammation and disrupts metabolic function. The encouraging news: even modest weight loss of 5-10% produces meaningful improvements in blood pressure, blood sugar, and cholesterol. A combination of gradual dietary changes, regular physical activity, and professional guidance is the most effective and sustainable approach.
How to Improve
Building habits for sustainable weight management
- Focus on whole foods: increase vegetables, lean protein, and fiber while reducing ultra-processed foods and sugary drinks
- Start with regular walking (aim for 7,000-10,000 steps daily) before adding more intense exercise
- Add 2-3 strength training sessions per week to build muscle, which increases resting metabolism
- Aim for gradual weight loss of 0.5-1 kg per week, as aggressive dieting leads to muscle loss and rebounds
Measuring with Apple Watch
Apple Watch does not measure weight or BMI directly. To track BMI over time, the most convenient method is a smart scale that automatically logs your weight to Apple Health. Popular options include Withings Body+, Renpho Smart Scale, and Eufy Smart Scale. These devices calculate BMI from your weight and height and sync the data wirelessly. Vita can import weight and BMI data from Apple Health to track your trends over time. For the most consistent readings, weigh yourself at the same time each day (ideally morning, after using the bathroom, before eating) and let the smart scale handle the BMI calculation.
Frequently Asked Questions
Is a BMI of 37 good?
Whether a BMI of 37 is good depends on context. The WHO classifies BMI 18.5-24.9 as normal weight, 25-29.9 as overweight, and 30+ as obese. Use the classification chart above to see where 37 falls. Keep in mind that BMI does not account for muscle mass, bone density, or fat distribution, so it is a screening tool rather than a definitive health measure.
How can I lower my BMI from 37?
To lower your BMI, focus on sustainable changes: increase whole food intake, reduce processed foods and sugary drinks, and aim for 150+ minutes of moderate exercise per week. Strength training helps preserve muscle during weight loss. Target 0.5-1 kg of weight loss per week for lasting results. Crash diets cause muscle loss and typically lead to weight regain.
Is BMI 37 the same for men and women?
Yes. The WHO BMI classification uses the same ranges for all adults regardless of gender: underweight (<18.5), normal (18.5-24.9), overweight (25-29.9), obese (30+). However, at the same BMI, men and women typically have different body fat percentages. Women naturally carry more essential fat. For a gender-specific assessment, body fat percentage is a better metric.
What are the limitations of BMI?
BMI only uses height and weight, so it cannot distinguish muscle from fat. A muscular athlete might have a BMI of 27 while being very lean. BMI also does not account for fat distribution (visceral vs. subcutaneous fat), bone density, age-related changes, or ethnic differences in body composition. Body fat percentage and waist circumference provide a more complete picture.
