Healthy eating and regular exercise play an important role to maintain health while ageing. Nutritional education and exercise practice could be monitored by different means, such as Internet, face to face and/or through exercise diaries. Information and Communication Technologies (ICTs) could be a useful tool to promote health, and could be used to work on barriers, such as low motivation and difficulties to maintain exercise or diet. ICTs also have other important advantages, especially their good cost-benefit relationship and the possibility of increasing the efficiency of interventions, allowing them to reach a wider audience at a lower cost. This study aims to describe a totally self-applied online program to promote healthy lifestyles (nutritional education and exercise practice) for obese participants with hypertension. Participants will be recruited from users of a hypertension unit of a public hospital and will be randomized into two groups: experimental group and control group (treatment as usual). The experimental program (3 months) will be composed by 8 modules aimed for promoting healthy eating habits and increase physical activity. Assessment will include: body composition (BMI), blood pressure, glucose metabolism variables, and physical activity level (measured with accelerometers).
