The Weight Log is the heart of SubtractTheFat. To get the most benefit from SubtractTheFat, you need to weigh yourself every day and then enter your weight in the Weight Log. If you have a Body Fat Analyzer you can also enter your Body Fat %.
SubtractTheFat uses the information in your Weight Log to calculate your Average Weight, your Body Mass Index (BMI), Resting Metabolic Rate (RMR), and Total Energy Expenditure (TEE).
SubtractTheFat also uses the information in your Weight Log to create your Progress Charts.
