This model shows the five-year effect of changing energy in and/or out on the female human body.
Set the values for initial body weight (lbs), energy intake (Kcal), deliberate exercise (Kcal), and initial percentage body fat by clicking on the arrows (< and >) or by clicking and holding the slider between the arrows. Be careful not to click too quickly or strange things will happen! Percentage body fat (%) and total body mass (kg) will be graphed against time (days) as the model runs. Note that total body mass is in kilograms, but initial weight is in pounds!
