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.
