A recent study suggests that a structured weight management program, combined with support from dietitians and peers, could help people with long COVID who are also living with excess weight.
However, researchers emphasize that the approach is complex and more studies are needed to confirm its effectiveness.
The study, known as the ReDIRECT trial, was conducted by researchers at the University of Glasgow and published in Nature Medicine. It tested a weight management program delivered remotely and designed to reduce the symptoms of long COVID.
Participants with long COVID symptoms lasting more than 12 weeks and classified as overweight took part in the six-month program.
Before starting, each participant selected one long COVID symptom they most wanted to improve. Commonly chosen symptoms included fatigue, breathlessness, and pain.
The program began with 12 weeks of total diet replacement, where participants followed a carefully controlled diet plan. This was followed by a gradual reintroduction of regular foods and ongoing support to help maintain weight loss.
Long COVID is a condition that can cause a range of persistent symptoms after recovering from the initial COVID-19 infection. While scientists do not believe that excess weight is a main cause of long COVID, exploring different treatment options is important because there is currently no cure.
The researchers believe that helping individuals manage their weight might offer some relief, even though the exact reasons for the improvement are not fully understood.
One key aspect of this study was the involvement of people with long COVID in shaping the research. Representatives from the group Long COVID Scotland collaborated with researchers from the very beginning.
Their input helped ensure the program addressed the real needs and experiences of those living with the condition.
Dr. David Blane, one of the lead researchers, explained that while it is difficult to measure how significant the health improvements were, the study showed encouraging signs. He said,
“Supported weight management could be a helpful part of rehabilitation for some people living with long COVID. The involvement of the long COVID community helped us better understand the condition and create a flexible program tailored to their needs.”
Professor Emilie Combet, an expert in human nutrition, noted that the program was not just about weight loss. “ReDIRECT was a complex intervention,” she said, “involving dietitian guidance, peer support, and remotely delivered weight management. Long COVID continues to affect millions worldwide, and further research is essential.”
Jane Ormerod, a representative of Long COVID Scotland, highlighted the importance of including people with long COVID in studies like this. “We were involved from the start to make sure the voices and experiences of those with long COVID shaped the research. We hope future studies continue to prioritize inclusive approaches to treatment and rehabilitation.”
This study sheds light on a promising way to manage some of the challenges faced by people with long COVID.
While the findings suggest that weight management programs might help alleviate certain symptoms, researchers caution that this is only a first step. More studies will be needed to fully understand the benefits and limitations of such programs.
The research findings can be found in Nature Medicine.
