There are many misconceptions around weight — starting with the fact that people burn fat differently depending on their size, says Mitchell Roslin, MD, director of bariatric surgery at Lenox Hill and Northern Westchester hospitals. On this episode, he breaks down the factors that contribute to obesity, from genetics and lifestyle to the way our bodies convert food into energy. Obesity itself has an impact on one's ability to lose weight due to something he calls the "metabolic switch." Dr. Roslin explains how weight gain is linked to other illnesses like cancer and when people should consider talking to their doctor about medical weight loss strategies, such as medications and weight loss surgery.
Dr. Roslin is a pioneer in the field of bariatric surgery, helping to develop advanced treatments like the single-anastomosis duodenal-switch, also known as SADI.
