Lack of physical activity and extended hours in front of screens are main causes of a sedentary lifestyle. According to recent studies, more than 60% of Canadian adults and 30% of children aged 5 to 17 are overweight or obese. Obesity and being overweight have physical, psychological and social implications and can help develop many health-related problems and illnesses such as diabetes, high blood pressure, cholesterol and other cardiovascular diseases. Dietary changes associated with physical activity and supplements like catechins found in green tea can help reach a healthy weight.
