It is not so much how you lose the weight as it is how much weight you lose that makes the difference in improving type 2 diabetes.
An ongoing large study presented May 7 at the International Congress of Endocrinology/European Congress of Endocrinology in Florence, Italy is showing that the of different types of weight-loss surgery made little difference in diabetes control in comparison to the amount of weight lost.

The study is following 2,010 severely obese people who were recruited to undergo weight-loss surgery, called bariatric surgery. The researchers led by Dr. Markku Peltonen at Finland’s National Institute for Health and Welfare wanted to understand why weight loss provides the well-documented improvement in type 2 diabetes control. One theory is that altering the time and amount of food going through the gut might explain some of the benefit.
“We would expect that some methods of weight loss surgery would be more effective at treating diabetes than others due to the different ways they alter the passage of food through our gut,” Peltonen said in a prepared statement. “When we factored in the weight lost following surgery we found that no procedure was any better at treating diabetes than another. Perhaps it is simply the act of losing weight that helps.”
The two main weight-loss surgeries take different approaches to shedding pounds. The banding strategy restricts the functional size of the stomach, making the patient feel full much sooner, causing them to consume less food. The bypass strategy reduces the capacity of the gut to absorb the calories. A third strategy combines the two.
To test the altered food transit theory, the researchers compared the long-term results of 376 people who underwent gastric banding, 265 who underwent gastric bypass, and 1,369 vertical banded gastroplasty, or combination surgery. The average weight loss over 10 years for all three groups was 39.6 pounds for the gastric banding group. The gastric bypass group lost an average of 44 pounds, and the combination group lost an average of 64 pounds.
After following the patients for 10 years the researchers found there was no significant difference in insulin and glucose levels among the three groups. When they compared the amount of weight loss, however, they found that those who lost the same amount of weight improved their insulin and glucose levels by about the same amount.
The researchers conclude that the remarkable improvements in diabetes following weight loss surgery are not related to the procedure itself. Instead the resulting improvement in type 2 diabetes is due to the weight lost.
