The researchers examined data from participants in the Look AHEAD study that compared the impact of 12 years of intensive lifestyle intervention with education and diabetes support.

Dr. Jonathan Shaw, the deputy director of Clinical and Population Health at the Baker Heart and Diabetes Institute in Melbourne, Australia, says the results of the study are promising, but they should be interpreted with caution.

“The results of this are very encouraging. One of the key reasons we aim to control diabetes or to achieve remission of type 2 diabetes is to reduce the risks of its serious complications, such as [chronic kidney disease] and [cardiovascular disease]. However, we do need to bear in mind that although the analysis is done within a clinical trial (Look AHEAD), this was not a trial result and is a non-randomized observational analysis. It is possible that people who are able to achieve remission are also people at inherently lower risk of [cardiovascular disease] and [chronic kidney disease],” Shaw, who was not involved in the study, told Medical News Today.

“We also need to remember that the main results of the Look AHEAD trial were that intensive lifestyle intervention in people with diabetes did not prevent [cardiovascular disease],” he added. “This new analysis suggests that there may have been a small group who did actually benefit from that intervention and this was the group that achieved diabetes remission. This is encouraging but not proof.”

A person is considered in remission from type 2 diabetes if they have normal blood glucose levels without diabetes medications for a period of at least three months.

In their new study, the researchers found that while 11% of people experienced remission after one year of follow-up period, by the 8^th year just 4% of were in remission.

Experts say this highlights the challenge for people with type 2 diabetes in keeping weight off.

“To achieve and maintain remission, it’s important to maintain the efforts that were necessary to achieve remission. Often, people are able to use more extreme or specific diets to achieve diabetes remission. For example, many patients do well with ketogenic diets in the short term. However, many of these more restrictive diets are not sustainable long term and it’s really key to find a diet that works and importantly is sustainable long term. If the person stops the diet or regains weight, the diabetes can return. It’s really about adopting a whole new way of approaching food and exercise,” said Dr. Marilyn Tan, a clinical associate professor of medicine specializing in endocrinology at Stanford University School of Medicine in California.

“Diabetes is multifactorial. Diet, weight, and lifestyle are part of the equation,” Tan, who was not involved in the study, told Medical News Today. “However, there are also other risk factors that are not necessarily modifiable. Sometimes, despite best efforts, diabetes may return due to genetics, other medical conditions, medications, and age.”

Of those in the study, people who had only had diabetes for a short time, had a low starting level of average blood glucose results, and had experienced significant weight loss were the most likely to go into remission.

However, remission for any amount of time was still found to lower risks of chronic kidney disease and cardiovascular disease.

In the United States, heart disease is the leading cause of death for women and men. Those who have diabetes are twice as likely to have a heart attack or stroke than people without diabetes. They’re also more likely to experience these health issues at a younger age.

The longer a person has diabetes, the more likely they are to also have heart disease.
