Reversing Type 2 Diabetes Through Weight Loss

Type 2 diabetes can be reversed, according to a new study published in the British medical journal Lancet. The secret? Weight loss.


The researchers, who were from the University of Glasgow in Scotland, recruited 306 people with Type 2 diabetes from various medical practices throughout the United Kingdom. The subjects ranged in age from 20 to 65 and had had diabetes for no more than six years. None were using insulin. The researchers then assigned 149 of the participants to follow what they called a “Counterweight-Plus weight management program,” which began with a three-month period in which the subjects’ daily food intake was cut by about 800 calories. Physical activities were left unchanged. The total intervention lasted one year.

After the year was up, the researchers discovered that 46 percent of those in the dietary intervention group were able to achieve remission of Type 2 diabetes, compared to only 4 percent in the control group. And the more weight the subjects lost, the more impressive the results. Those who gained weight had a 0 percent remission rate. Those who lost 0–11 pounds had a 7 percent rate; 11–22 pounds brought a 34 percent remission rate; 22–33 pounds meant a 57 percent rate; and the remission rate from Type 2 diabetes for those who lost 33 pounds or more was a whopping 86 percent.

The researchers plan to follow their subjects for at least four more years to see how they fare with their diabetes in the longer term. But for now, the results are most heartening for those scientists seeking a “non-pharmacological” approach to treating diabetes. According to Michael E. J. Lean, MD, one of the study authors, “Our findings suggest that even if you have had Type 2 diabetes for 6 years, putting the disease into remission is feasible.”

    The US national “look ahead” study looked at weight loss with a much larger population and found no statistically significant effect from weight loss. This smaller study should be taken with a grain of salt.

    Weight loss for diabetics remains a major subject of discussion almost all the time in the various forums I have joined for the purpose of information and support. Having been type 2 diabetic for more than a quarter century I can support this theory of reversing diabetes through weight loss for I was injecting myself with 46 units of insulin per day which I no longer do because of various interventions weight loss included and thus reversing my diabetic status.

    This was a very interesting blog post about losing weight to reduce diabetes. I knew about this but I did not know much detail about it. I thought the results of the study were very inspiring to others and could encourage them to participate too. Thank you for sharing.
