Body Mass Index: Weight ( in Kilograms)/ Height ( in m2)

Grades of obesity (Standards for South Asians)

Grade III    >40
Grade II     30 40
Grade I    23 29.9
Normal     18.5 22.9

Waist Circumference

It is the most practical tool for clinicians to evaluate a patients fat level.

Women     < 80 cms
Man     < 90 cms

Regional distribution of adipose tissue
Android obesity (apple shape):

it is characterized by fat distributed predominantly in the upper body above the waist. A pattern usually observed among males.
Gynecoid obesity (pear shape):

It is the accumulation of fat in the lower abdomen that is the buttocks, hips and thighs. A pattern normally observed among women.
Obesity in the abdominal region is associated with metabolic derangements such as; insulin resistance, hyperinsulinemia, non insulin dependent diabetes (NIDDM), hypertension, and hyperlipidemia.

Mechanism: Due to the lipolytically sensitive abdominal depots providing excess free fatty acids to a muscle tissue that has decreased capacity for their oxidation.

Fat cells from the upper body are functionally different from the cells in the lower body. In the former there is hypertrophy but in the latter there is hyperplasia.

Metabolic changes among the Obese
  • Reduced glucose tolerance
  • Reduced insulin sensitivity
  • Increased plasma insulin
Response to starvation
  • Reduced production of ketone bodies
  • Increased plasma free fatty acids
  • Increased Triglycerides
  • Increased Cholesterol
  • Increased Uric Acid
  • Reduced sensitivity to Growth hormone
