If you consume more energy than your body use in the course of the day, you will become overweight. It’s all about finding your energy balance.
The role of sugars in obesity and the development of non-communicable diseases, such as type 2 diabetes, is much debated. However, the risk of overweight and obesity relates more closely to energy balance or energy imbalance – energy intake exceeds the energy expended by the body – than it does to the sugar content of the diet. Overweight and obesity develops when an individual’s energy intake is greater than his or her energy expenditure, which is why the whole diet is relevant and not one single food. Excessive consumption of calories from any source is the main cause of obesity, not the foods providing the calories.
Development of overweight is a result of interaction between a number of different factors including genetics, diet and exercise habits, and psychosocial aspects. Research also indicates that overweight is correlated with social status and education. So there are many factors to take into consideration when we want to solve the overweight problem. Unfortunately, it is not enough to focus solely on one single factor such as the sugar content of various products or the number of PE lessons at school.
