A new study reveals that the 5:2 diet, which involves cutting calories for two days a week, is as effective as standard daily calorie restriction for weight loss and blood sugar control in people with type 2 diabetes. The year-long clinical trial by the University of South Australia involved 137 overweight participants with type 2 diabetes, split into two groups: one following the 5:2 diet (500-600 calories on two non-consecutive days) and the other on a traditional daily limit of 1,200-1,500 calories.
Results showed that those on the 5:2 diet lost an average of 15lb (6.8kg), compared to 11lb (5kg) for the traditional diet group. Among the most determined participants, average weight loss was 27.5lb (12.5kg) on the 5:2 regime versus 18.5lb (8.4kg) on the standard diet. Researchers noted the 5:2 diet 'may be superior' but called for larger studies.
The 5:2 diet, championed by Dr Michael Mosley, involves fasting two days a week and eating normally the rest. Previous research has linked it to reduced breast cancer risk and improved brain function. The study offers hope to nearly 3.7 million UK residents with type 2 diabetes who could benefit from this flexible approach.
