Metabolic syndrome (MS) is a collection of conditions such as obesity, high blood pressure and impaired ability to balance blood sugars, that increase the sufferers risk of diabetes, stroke, and heart disease. Weight loss and lifestyle modifications are the main recommendations to improve MS. Intermittent fasting is a dietary regime that involves restricting the intake of food to certain times of the day, without restricting calories and has been shown in animal and human studies to result in fat loss and an increased ability to balance blood sugars. This randomised control trial of 218 adults over 6 months aimed to firstly determine relationships between eating duration, unprocessed and processed foods, and lifestyle factors on health and secondly to determine if a 12-hour time restricted eating pattern leads to an improvement in MS. The results showed that higher consumption of processed foods was associated with poorer metabolic health. A 12-hour restricted eating pattern resulted in weight loss, whereas individuals on a standard daily eating pattern did not, however differences between the two groups were not significant. Other measures of metabolic health failed to show any differences between the two groups. It was concluded that a 12-hour restricted eating pattern was feasible over 6 months, however further research is needed to assess if a more restricted time would result in greater weight loss. This study could be used by healthcare professionals to understand that a restricted eating pattern may be of benefit to those with MS, however further research would be needed to determine the optimal timeframe.
