Obesity is a condition in which excess build-up of fat leads to potentially adverse health conditions. Hypertension, heart disease, type 2 diabetes, sleep apnoea, stroke and even cancer are more likely in people who are obese. And while multiple factors may be involved in how obesity develops in the first place, certain lifestyle and nutritional changes may be the best way to improve the condition.

Obesity is common, affecting between 10 and 14 percent of adults worldwide. It is defined as abnormal or excessive fat accumulation that may impair health. Obesity is a medical concern because of the secondary health problems associated with it. Risks linked to obesity include heart disease, hypertension, type 2 diabetes, cancer, breathing problems and kidney and liver diseases.* Even losing a portion of the excess fat, around 10 percent, can substantially reduce the risk of many of these secondary conditions.1

While obesity is ultimately a condition caused by an imbalance between caloric intake and daily energy expenditure, multiple factors can lead to such an imbalance. In addition to eating excessively, several other factors such as genes, the surrounding culture and infrastructure, amount of sleep and even some medications may influence unintended weight gain. While some of these factors are out of a person’s control, lifestyle habits and nutritional intake can be adapted to make this condition less likely, or to help someone lose the excess fat they have already gained.2

As a caloric imbalance is the primary cause of obesity, correcting this imbalance may be the most effective way to address it. Both increasing activity (burning more calories) and reducing intake (eating fewer calories) can help restore a proper energy balance. At Nestlé Health Science, we are actively engaged in developing nutritional therapies to help improve conditions like obesity and the quality of life of patients with such conditions.

Losing a small amount of weight can reduce the risk of comorbidities.

Starting to exercise regularly can seem like a daunting task for people who are obese. However, small changes, like taking the stairs instead of elevators, parking a car farther from a destination or going for walks after meals can all add substantial energy expenditure to an otherwise sedentary lifestyle.


Part of the reason obesity is so common and on the rise is the availability of high-calorie (especially high-fat), low-nutritional value foods (like soft, sugary drinks). Substituting nutritious foods like fruits, vegetables and lean meats, and drinking more water can help bring caloric balance under control to better deal with obesity.
