So, we applied our long-term expertise in computer vision (CV) and machine learning (ML) towards developing “Body,” a feature within Amazon Halo, our new health and wellness membership. Īt Amazon, we believe everyone should have access to important, clinically relevant information about their own health. This assumption often does not hold in practice and limits accuracy. Further, these tools assume a constant density for fat-free mass and do not take into account densities for bone and muscle across users. These are more accurate than at-home smart scales but require access to a trainer or special facility, and each scan costs money. Then, there are commercial-grade measurement tools like hydrostatic dunk tanks and pods. Based on how hydrated you are throughout the day, this electrical resistance can fluctuate wildly, leading to high errors in BFP. The scales do not measure body fat, but analyze electrical resistance in the body and use equations to convert that to BFP. Medical professionals like myself have known this for some time, but measuring BFP can be difficult, expensive, and inconvenient-even at-home smart scales that try to measure BFP have high error rates. That’s because, at the most fundamental level, obesity is synonymous with having too much body fat. īody fat percentage (BFP) is a better overall indicator of health and longevity than weight or BMI alone. A recent systematic review of over thirty clinical research studies concluded that BMI has serious limitations for use as an obesity screening tool in clinical practice despite its widespread use. Muscle and bone are denser than fat, so people who are very muscular can end up being classified as obese based on BMI, yet not have much fat. Body Mass Index (BMI) is often used as a more reliable measurement of health because it accounts for both height and weight-in fact, it’s commonly used by doctors to screen for certain medical conditions like obesity and to make care recommendations -but BMI can also be misleading because it doesn’t distinguish between muscle and fat. But weight alone can’t tell you how much of your body is muscle, fat, bones, water, or even the donut you ate for breakfast. In fact, people often say that “maintaining a healthy weight is the most important thing you can do for your health.” That’s because being overweight or obese presents a risk to your health it can lead to diabetes, heart disease, and even cancer. Historically, weight has been the go-to metric used to judge how healthy we are.
