It remains unclear why long-term weight loss is so difficult. It was hypothesized that obesity produces persistent changes in behavior that bias animals toward weight regain after weight loss. METHODS Mice were induced to gain weight with a high-fat diet for 6 weeks and then induced to lose this weight with a low-fat diet for 7 subsequent weeks. A control group was maintained on the low-fat diet for all 13 weeks. Activity was measured continuously with home cage activity monitors for the entire experiment. Motivation for sweetened food pellets was tested following weight loss. A separate group of mice was reexposed to a high-fat diet following 2, 4, or 8 weeks of withdrawal to assess the rate of weight regain. RESULTS Activity levels decreased as animals gained weight and partially recovered following weight loss. Motivation for sucrose pellets was persistently heightened after weight loss. Consistent with these behavioral changes, mice also regained weight at a faster rate when reexposed to a high-fat diet after a period of weight loss. CONCLUSIONS Weight loss after obesity was associated with increased motivation for palatable food and an increased rate of weight regain. Published 2020.

METHODS The patients were divided into guide template group and conventional perspective group. In the conventional perspective group, the screws were placed by hand under fluoroscopy. In the guide template group, the screw placement was aided by a new drill guide template
