"High blood pressure can be caused by excessive wieght and lack of exercise" justify this statement.
High blood pressure can be caused by excessive weight and lack of exercise because weight gain is a result of consuming fatty foods that get stored in the body as reserve energy. The accumulation of the fats narrows the lumen of arteries and increase the blood pressure. Exercise on the other hand helps to consume the extra calories of the body and prevents the excess accumulation of fats in the body which in turn keeps blood pressure normal. Thus, we can say that excessive weight and lack of exercise increases blood pressure.
