Fig 2.
Total physical activity during awake time and during night time analyzed by three-axial accelerometers (Actigraph GT3X+) in six female subjects before and during weight loss (10 days and 3 months postoperatively) and at weight stability 20 months after gastric bypass surgery.
*; significant difference to visit 1; * = p<0.05. ¤; significant difference to visit 3; ¤ = p<0.05.
Fig 3.
Six female subjects assessed for energy expenditure during and after a 600 kcal standard meal intake, from 18:00 to 21:00h.
Time for food intake was standardized to 20 minutes. Assessments were performed before, visit 1, and at weight stability 20 months after, visit 4, gastric bypass surgery. Data are presented as MAT; energy expenditure exceeding BMR and NEAT adjusted for total tissue; mean cal/min/kg.
Fig 4.
Six female subjects assessed for energy expenditure during one hour after a 600 kcal standard meal; from 18:20 to 19:20.
Assessments were performed before, visit 1, and at weight stability 20 months after, visit 4, gastric bypass surgery. Data are presented as mean values in kcal/minute and as percentage of total energy expenditure.
