Expat insurance customers with type two diabetes may be able to benefit from a low-calorie diet after a study revealed this can improve heart function and eliminate the need for insulin.
The research was presented at the annual meeting of the Radiological Society of North America and led by Sebastiaan Hammer MD from the Leiden University Medical Center's Department of Radiology.
Participants in the study ate only 500 calories every day and had their pericardial fat and heart function monitored beforehand and four and 14 months afterwards.
It found reducing calorie intake for 16 weeks resulted in increased heart function, which was persistent in the long-term regardless of subsequent weight increases.
However, the researchers said not everyone should have this kind of therapy and individuals ought to discuss their options with their doctor before altering their food consumption in this way.
"It is of utmost importance to follow such a complicated intervention under strict medical supervision," Dr Hammer argued.
Gum disease is closely correlated with diabetes, British Society of Periodontology president elect Philip Greene recently claimed.
