Individual weight changes up to 2.5 years after hyper-alimentation in the intervention- and control group. Individual weight changes (kg) in 18 healthy individuals before and after hyper-alimentation while simultaneously having a sedentary lifestyle for four weeks and when followed-up 2.5 years later compared with the control group of 18 individuals. Two and a half years after the intervention body weight showed a further increase (p = 0.01) in the intervention group while the weight of the controls was unchanged compared with baseline (p = 0.88). Changes in weight after 2.5 years significantly differed between the two groups (p = 0.015). The figures in the graph correspond to 6 women (a) and 12 men (b) in the intervention group and in 6 women (c) and 12 men (d) in the control group at baseline and after the intervention. Two and a half years after the intervention data was missing in 3 subjects of the intervention group and in one subject of the control group.
