How to use this estimate
This is a simplified energy-balance projection. Actual weight change may slow or fluctuate as maintenance needs, water weight, activity, and body composition change. Do not enter exercise calories twice if they are already included in maintenance calories. This tool does not prescribe a minimum calorie intake or provide medical nutrition advice.
