According to doctors at UT Southwestern Medical Center, having weight loss surgery doesn’t mean you have to take it easy on exercise.  The study of 33 people with an average BMI of 41, were selected into either a 12-week exercise program or to a control group.  All participants were given dietary counseling and told to keep their daily calorie intake between 1,200 and 1,500 calories. The 21 participants randomly assigned to the exercise group worked out at least five days a week, gradually increasing the number of calories burned from 500 the first week to at least 2,000 calories in the final week. 


The study found that after weight loss surgery, exercising regularly at a moderate to vigorous pace my be perfectly fine – and might improve one’s quality of life.  Those in the exercise group increased their daily step count form 4,500 to 10,000 steps per day, indicating that they did not reduce their movement the rest of the time.  All the participants in the study lost on average 10 pounds however those in the exercise group were found to have become more aerobically fit. 


The American Society for Metabolic Surgery reports that of the 15 million people nationwide who are morbidly obese, some 220,000 of them underwent weight loss surgery in 2009.  Up until recently it was unknown whether morbidly obese bariatric surgery patients could undertake rigorous exercise programs but according to the study’s senior author Dr. Abhimanyu, the study appears to indicate that most bariatric surgery patients can perform large amounts of exercise and improve their physical fitness levels.” 


**NOTE: Always check with your surgeon before beginning an exercise program
