The balance between calories intake and energy expenditure determines a person's weight.



The most common causes of obesity are overeating and physical inactivity. Ultimately, body weight is the result of genetics, metabolism, environment, behavior, and culture.



Lack of exercise : Lack of exercise stores the calories as fat in the body; which results in gaining body weight.

1



Genetics. A person is more likely to develop obesity if one or both parents are obese. Genetics also affect hormones involved in fat regulation

2



Overeating. Overeating leads to weight gain and also

Foods high in fat or sugar (for example, fast food, fried food, and sweets)

have high energy density.

3

Frequency of eating: People who eat small meals four or five times daily, have lower cholesterol levels and lower and/or more stable blood sugar levels than people who eat two or three large meals. Especially diets high in simple carbohydrates

4

Slow metabolism. Muscle burns (metabolizes) more calories than other tissue (which includes fat). As a result, people with slower metabolism have a tendency to put on more weight.

5



Medications. Medications associated

with weight gain include certain antidepressant,

oral contraceptives as well as some high blood

pressure medications

6



7 Physical inactivity. Sedentary people burn fewer calories than people who are active. Research showed that physical inactivity was strongly correlated with weight gain.



Psychological factors. For some people, emotions influence eating habits. Many people eat excessively in response to emotions such as boredom, sadness, stress, or anger.

8



Diseases such as hypothyroidism, insulin resistance, polycystic ovary syndrome, and Cushing's syndrome are also contributors to obesity
