Exercise + diet
Diet only
Exercise intervention: During the first session a standardized exercise prescription will be discussed with the participant. The exercise program will be of a moderate intensity, at less than 140 heart beats/min (which corresponds to 60% of the calculated maximum heart rate (HRmax) or 50% maximum oxygen volume (VO2max) ). A session of 30 to 60 minutes/week will be organised. Participants will be instructed to conduct a nonsedentary lifestyle. They will be encouraged to increase their number of steps on a daily basis and perform not more that 45 minutes of continuous exercise per day. Pedometers will be used to measure the compliance and as a positive feedback for motivation. The participants will return to the exercise laboratory once per week for Actiheart data downloading, number of steps recording, exercise support and counselling, and to perform the supervised group exercise intervention. This is in addition to the diet (see below, control group)
Participants will receive diet counselling according to their characteristics. The usual recommendation is to have a fractioned normocaloric diet (unless the dietician identify a grossly hypercaloric diet), with low fat and increase in fibers content.
