This model shows the five-year effect of changing energy in and/or out on the male 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 dragging 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!
