POOR DIET


POOR DIET
  Obesity is  a chronic condition defined by an access amount of body  fat .A certain amount of body fat is necessary  for storing energy ,heat insulation ,shock absorption  and other body functions .The normal amount of body fat(expressed in percentage of body fat)   is between 25-30%  in women. Women with over 30%body fat are considered obese.
Most of women do not even know their body mass Index and its calculation has been used in the definition of obesity. The body mass index (BMI) is equal to a person’s weight in kilograms (kg) divided by their height in meters (m) squared .Since BMI describes body weight relative to height; it is strongly correlated with total body fat content in young adults.

 The balance between  calorie intake and energy expenditure determines a person’s body weight .If a person eats more calories than he or she burns (metabolizes),the person gains weight .The body stores the excess energy as fat .The following factors are believed to contribute to Obesity among women

1 .Genetics: One is more likely to develop obesity if both parents are obese .Genetics also affect hormones involved in hormone regulation.  For example one genetic cause of obesity is leptin deficiency .Leptin is a hormone produced   in fat cells and also in the placenta. Leptin controls the weight by signaling the brain to eat less food when body fats are too high .If for some reason the body the body cannot produce enough leptin, this control is lost and obesity occurs.
2. Overeating: Most of the women like eating fries like chips. Fatty foods (fast foods, fried foods and sweets) have a high energy density.
