Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health. A crude population measure of obesity is the body mass index (BMI), a person's weight (in kilograms) divided by the square of his or her height (in metres). A person with a BMI of 30 or more is generally considered obese. A person with a BMI equal to or more than 25 is considered overweight.

drinking too much alcohol - alcohol contains a lot of calories, and people who drink heavily are often overweight
eating out a lot - you may be tempted to also have a starter or dessert in a restaurant, and the food can be higher in fat and sugar
eating larger portions than you need - you may be encouraged to eat too much if your friends or relatives are also eating large portions
drinking too many sugary drinks - including soft drinks and fruit juice
comfort eating - if you have low self-esteem or feel depressed, you may eat to make yourself feel better
