Wondering how to determine your own body type? Your first easy step is something you do every day -- look in the mirror.

The Bodytype.com staff compiled the following pictures and simple charts to help you narrow down your body type choices. Remember, however, noticing your main area of weight gain is just the first step to determine your body type.

Your dominant gland determines certain physical and psychological characteristics. Some types gain weight in their lower body. Other types carry their weight in their upper body. The trick is to notice your unique pattern of weight gain and compare yourself against the photos and profiles found in Different Bodies, Different Diets.

After viewing the charts and pictures, you may see yourself in a number of types. That's normal -- many body types share common physical characteristics. However, a careful reading of the Psychological Profiles (found in Different Bodies, Different Diets starting on page 149) will indicate the choice that's right for you.

If you already own Different Bodies, Different Diets -- grab your copy! You can enjoy this interactive test while you follow along with the book. Just turn to page 20 to get started right now! You'll learn how easy it is to discover your unique type.
