Body Metrics
Calculate BMI, daily calorie needs, and protein targets from your height and weight with error bounds.
Computes BMI, basal metabolic rate, total daily energy expenditure, and protein targets from height, weight, age, sex and activity level. Uses multiple standard equations and reports uncertainty ranges. Accepts flexible unit formats and rejects implausible values.
Try asking Muse: "What's my daily calorie burn and protein target based on my height, weight, and activity level?"
