Overweight

Obese
Significantly increased risk for cardiovascular disease.
BMI has limits. It doesn't account for muscle mass, bone density, age, or fat distribution. Athletes often show "overweight" BMI while being very healthy. Use it as one data point, not the whole picture.
A number today. A trend that matters.
SlayCal logs your weight automatically and shows your BMI trend over time — so you see progress, not just a snapshot.
