The survey conducted by research agency YouGov has found that 86 percent of slimmers who continued enjoying their favourite treats successfully lost weight, the New York Post reported.
It was found that of the 2100 men and women surveyed, those who lost the most weight- 91 percent of cases- had continued to eat the same amount of chocolate they normally ate before going on a weight-loss plan.
Janet Aylott, a nutrition scientist with online calorie counting plan Nutracheck, who commissioned the YouGov survey, said that extensive research has proven that diets cantered around food elimination are much more likely to fail.
Meanwhile, another research by researchers at Harvard University has suggested that eating chocolate may help you live longer.
The team, which conducted the study for 65 years and studied 8000 men, found that those who ate modest amounts of chocolate up to three times a month lived almost a year longer than those who ate none.
