Liver failure is usually taken as a sign that you are drinking too much alcohol but a new study published in the specialist journal Diabesity in Practice has found that starchy-heavy diets can cause liver damage.

Dr David Unwin discovered this after he selected 69 patients who had very high levels of GGT and put them on a low-carb diet for 13 months.

Your liver health can be measured by a blood test for a protein called gamma-glutamyl transpeptidase (GGT). If your levels are high, it suggests your liver is under pressure.

According to a Daily Mail report, the patients ate mainly green veg, lower-sugar fruits such as blueberries, nuts, fish, eggs and meats. The essence of doing this was to cut out all added sugar and reduce starchy carbs such as bread and potatoes.

“The results were striking,” says Dr Unwin. “The first thing that happened was that their GGT readings dropped by an average 47 per cent. That makes sense because the liver is the first destination of new glucose supplies”.

The trial by Dr David Unwin was supported by the British Liver Trust which said the results from the trial held out the hope that low-carb diets could help cut premature deaths from liver disease.
