There are two types of body fat:
  1. Essential fat.
    This is needed for the body’s hormone and immune systems to function properly and is stored in the body’s major organs such as the heart, lungs, bone marrow and muscles. Women carry additional essential gender-specific fat in the breasts, pelvis, hips and thighs, which is a biological necessity for child bearing. Essential fat accounts for at least 8% to 12% of a woman's total body weight. Men should not drop below 6% body fat.
  2. Storage fat.
    This is used as fuel for the body in times of need and is also required for good health. It is used to protect the internal organs in the chest and abdomen. The levels of this fat fluctuate, as this is the weight that changes during weight gain and loss.

SUPERSKINNY?

It is impossible to decrease body fat levels to zero. Essential fat and some storage fat is a required for normal body functioning. This is particularly true for women, in whom very low levels of body fat may cause a disruption/ loss of the menstrual (amenorrhea) cycle, this in turn resulting in an oestrogen deficiency, infertility, hair loss, a decrease in bone density and premature osteoporosis. Generally, any woman who seeks to maintain her body fat levels below 12 – 15 % and/ or trains very heavily will experience this disruption. However, this may also depend on how this body fat percentage was achieved and is maintained. The point of amenorrhea is different for all women, for some it may be at 18%, for others at 16% or 12%. It is important to understand that even with resumption of normal menses, some of the changes that have taken place may be irreversible, such as bone mineral loss (increasing risk of osteoporosis - brittle bones).This is particularly true in adolescence, during which, 60 – 80% of skeletal bone is laid down and consolidated. Low oestrogen levels during this time will causeinhibition of normal pubertal growth and development.

Amenorrhea is never healthy, desirable or acceptable. This is a sign that something is wrong.
If you stop menstruating after a period of weight loss, it may be that you have gone too far. Try putting on a little weight to see whether this restores your menses and make an appointment with your general practitioner.
