Table 2 Body composition in 18 healthy individuals as measured with Dual energy x-ray absorptiometry (DXA) before and after an intervention with hyper-alimentation while simultaneously having a sedentary lifestyle for four weeks and when followed-up 12 months later

From: Long-term increase of fat mass after a four week intervention with fast food based hyper-alimentation and limitation of physical activity

  Baseline Women n = 6 Men n = 12 After intervention Women n = 6 Men n = 12 12 months after intervention Women n = 6 Men n = 10 Baseline vs after intervention* p-value Baseline vs after 12 months* p-value

  1. All figures are means (SD). All subjects participated at baseline and after the intervention. Twelve months after the intervention 16 subjects were included.
  2. BF = Body fat, FM = Fat mass, FFM = Fat free mass, BMC = Bone mineral content, FMI = Fat mass index and FFMI = Fat free mass index.
  3. *Comparisons are made with Students paired T-test.
