FOUR out of five people who started a diet for the new year will have given up by today, according to a new survey.
A survey of 2,000 adults also showed that one five failed to continue with a new year resolution on healthy eating within a few days.
The main diet-breaking foods were chocolate, bread, crisps and takeaways, the study - by V8 juice - found.
More than one in four of those polled admitted they didn't eat enough vegetables and almost a third said they ate too much processed food.
Kamalesh Subramaniam of V8 said the results were "shocking" and showed that Britons were obsessed with extreme crash diets which were impossible to maintain.
Another survey, of 2,000 adults, showed that more than half of all British drinkers who vowed to have a dry January had failed after only two weeks of abstinence.
Almost one in 10 adults had planned to remain alcohol-free throughout this month, according to research commissioned by the Pharmacy2U Online Doctor service.
