The most common method used to define obesity is the BMI (weight/height squared in meters). If a person’s BMI is 30 or above is considered to be obese. In this review we focus on the different factors that cause obesity and on the different available treatment strategies. The mechanism behind weight gain is based on the energy intake of an individual. Positive energy balance leads to gain weight. With rapid economic growth, urbanization and westernization traditional diets high in fibres were replaced by diets high in sugar and fats which are high in energy and lead to a positive energy balance and therefore gain weight. Also, energy high food prices have declined leading to increased consumption of the latter. Fast foods which sell low quality/ energy high foods for a convenient price are an example of this phenomenon. Daily choices also influence the prevalence of obesity. For instance, eating out often can expose individuals to larger portions eventually leading to the phenomenon of portion distortion. Physical activity affects the energy balance of an individual along with dietary choices. Increase in physical activity, as shown in different studies, promotes weight loss. Combining low-fat diet with either vigorous exercise or simple lifestyle activity has been proven to be the best modality for weight loss. There are three main management strategies that can be followed in order to lose weight: lifestyle changes, pharmacotherapy and surgery. The primary approach to treat obesity is weight loss through diet and exercise, supported also by behavioural therapy. The aim of the diet should be lowering the calorie intake. People should first of all inform themselves about the different macronutrients normal intake levels and consult an expert. If no adequate weight loss is achieved by lifestyle changes, medications like Orlistat may be taken. If medications and lifestyle changes aren’t successful, surgery may be considered as an option to lose weight.Keywords: Obesity, nutrition, diet, physical activity, management, lifestyle, BMI, weight gain, weight loss
