Body fat monitors

Using body fat monitors is a great way to keep track of your weight loss. Simply using a scale doesn't show what weight you're losing - many crash diets take off mostly water and muscle!

Body fat monitors, however, will let you know if you are getting rid of the blubber. They are widely available, built into bathroom scales, starting as low as ?35. For a tool that will let you accurately chart your progress, that's a pretty small price to pay.
