Obesity is a condition in which a person has excess of body fat. A normal person has about 30 to 35 billion fat cells. When a person gains weight, the fat cells grow in their size and later on, start increasing. A BMI of 18 to 24 is considered the normal weight, 25 to 29 are considered overweight and any person who has a BMI of 30 or higher is considered obese.

A proper nutrient diet helps people in maintaining the body’s calorie need. Rich source of vitamins and minerals help people in meeting their body needs. What makes obese people different from normal people is that normal people follows a regular nutrient diet at a proper time and do regular exercises, where as obese people take food at their wish. Physical inactivity is also a main cause.

While it’s long been known that it is better to be fit and fat than being thin and sedentary, now thinness has become a prerequisite of attractiveness.

Causes of being obese
Physical inactivity is one of the important factors for both overweight and obesity. Genetics, family history and age also determine the size of an individual. Eating too much of wrong foods, attitude, lifestyle and interpersonal factors are also important causes for obesity. Stress has also been cited to be a cause to many of the health problems associated with weight. Eating junk food and consuming alcohol are also practices generally considered unhealthy.
