There are four types of bodies as classified on fatness :

(1)Android

Approximately 40% of women (and most men) belong to this body type which is characterized by broad shoulders, strong muscular arms and legs, a narrow pelvis and narrow hips. If these people gain a lot of weight they tend to become apple shaped.

(2)Gynoid

Approximately 40% of women belong to this body type which is characterized by small to medium shoulders a narrow tapering waistline and wide hips. Weight gain tends to occur on the buttocks and thighs which further accentuate the pear shape of the gynoid type.

(3)Thyroidal

Approximately 10% of the women and 5% of the men belong to this body type which is characterized by a fine (small) bone structure relatively long limbs compared to the trunk and a long narrow neck. We call them thyroid types because they have such a rapid and efficient metabolism and not because they are more likely to suffer with thyroid diseases.

(4)Lymphatic

Approximately 10% of women and 5% of men belong to this type which is characterized by weight gain all over the body. The limbs have a thick puffy appearance and the bone structure is not very visible they have an inefficient lymphatic system which leads to water retention and makes these people appear more fatter than they are. Cellulite is common in these people.
