The liver damage is caused by consuming high levels of glucose because it gets converted into fat in the liver. It doesn't only damage the liver but also can cause diabetes and heart disease.
Apart from drinking habits, you also need to control your diet otherwise you may also suffer from liver failure.
The vitality of liver is measured by a blood test for a protein called gamma-glutamyl transpeptidase (GGT). High levels of GGT are found in people who consumes a large amount of starch with little or no drinking habit.
Nearly 20% of Briton suffer from this condition.
Dr David Unwin, from Southport Merseyside, explained,''Sugar and starchy food cause a problem because they are rapidly turned into glucose and the body's first port of call for storing glucose is in the liver,' he says. What the liver can't store is then stored as body fat. The solution, he says, is simple: 'a low-carbohydrate diet. That means less glucose in the liver and so less fat.'
He selected 69 patients having very high level of GGT who were asked to take low-carbohydrate food for 13 months. They consumed lower- carb fruit, high amount of healthy fats from olive oil and butter but avoided starchy foods such as bread and potatoes. Dr Unwin said,'The results were striking. The first thing that happened was 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 treatment of the fatty liver disease lies in the daily dose of the diabetes drug liraglutide which helps in reducing weight. Dr Unwin said, 'It's hardly an ideal treatment,' says Dr Unwin. 'The drug needs to be injected daily and comes with the risk of nausea and diarrhoea. It also costs the NHS £1,400 a year.'
Dr Unwin said, 'Non-alcoholic fatty liver is the third great epidemic of modern times, joining diabetes and obesity as major threats to health. And sugar and carbs look like the culprits. It's tempting to hope that having eaten our way into all three epidemics, we can eat our way out again by cutting back on sugar and starch.'
Alan Threlfall, 43, who participated in Dr Unwin's fatty liver test said, 'I was sleeping 18 hours a day. I was so tired every step was like walking though wet concrete.'I'd run a marketing business with my wife Katy, but I had to stop that two years ago. I was ready to throw myself off a building.' Alan described the diet suggested by Dr Unwin as a miracle. 'Within a week, I felt the fog of fatigue start to ebb away. Just being able to play with the children is wonderful.'
