The researchers studied a mouse mannequin of vertical sleeve gastrectomy, a type of weight loss surgery through which the abdomen is decreased to about 15% of its authentic measurement. After the process, a number of the mice remained on the high-fat weight loss program they have been fed earlier than surgical procedure, whereas others have been positioned on a lower-calorie weight loss program.
