There are 4 stages in the development of your BMI

Phase 1: Baby fat

Newborn body mass must be low enough to pass through the birth canal. After birth, babies accumulate fat mass as an energy reserve for growth and as a protection against impacts in cases of falling and other accidents. The BMI reaches a peak at about the age of seven months.

Phase 2: Initial lankiness

Toddlers use up most of their baby fat, and the shape of the body begins to change. The growth in length exceeds the growth in mass, thereby resulting in a decreasing body mass index. Its minimum is reached at the age of about six years.

Phase 3: Growing up

In childhood and adolescence the body grows both in length and in mass. The latter increases to a faster extent, resulting in an increasing body mass index. The body gradually develops into an adult shape.

Phase 4: Adulthood

After the body has reached its final length, the BMI curves flatten, but continue to increase at a slower speed because a certain amount of body mass is still accumulated with age.
