Obesity is defined as abnormal or excessive fat accumulation in the human body that presents a risk to health by World Health Oraganization. Obesity can be measured using 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. However, these standards varying from ethnicity to ethnicity. 

Obesity is a major part of metabolic syndrome which is a major risk factor for a number of chronic diseases, including diabetes, cardiovascular diseases and cancer. 

"Once considered a problem only in high income countries, overweight and obesity are now dramatically on the rise in low- and middle-income countries, particularly in urban settings" - WHO

Recent research has been found that Higher rates of obesity and ill-health can be observed in shift workers than the general population (By James Gallagher - Health editor, BBC News website)

Why? There are many reasons associated with this Fact. 

Erratic working schedules lead to consume food away from home mainly in cheap fast food restaurants. They are rich is calorie, sugar, fat (Saturated fat, Trans fat, cholesterol), salt and low in micro nutrients and fiber. Also massive portion size tend to accumulate these unhealthy food inside your body more and more. 

Erratic workers do not eat in a regular pattern and they skip their main meals such as breakfast and lunch. As a result they tend to eat more calorie rich food in night and stomach do not have adequate time for digestion because soon after eat, they go to sleep. This lead to increase abdominal fat which carrying increased risk for cardiovascular diseases. 

Furthermore, these people tend to consume more alcohol and cigarettes in order to prevent loneliness or to obtain a fun. For examples, if group of male employees go around the country for marketing definitely most of the nights they organize party with alcohols.  

On the other hand, they do not have time to engage in physical activities and increased level of stress can also lead to obesity and hypertension. 

"Shift work is becoming increasingly common and it's causing a lot of problems to a lot of people and in particular the link with cancer is becoming stronger (By James Gallagher - Health editor, BBC News website)"

Therefore to alleviate this problem nutrition intervention strategies should mainly target for these set of people as well out of the main set of general population.
