UK employees are not doing enough to improve their health and wellbeing, with 20% of men and 15% of women not getting their "five-a-day."
Not exercising at all was reported by 19% of men and 24% of women of the 16,808 people surveyed for The Health Insurance Group and Wellbeing People's research.
Drinking regularly was reported by 30% of men and 26% of women, while 60% of men and 50% of women sometimes consuming more than 6 drinks a day, while 12% of men and 7% of women regularly doing so.
Smoking was a regular habit for 18% of men and 15% of women, the research found.
Ben McGannan, managing director of Wellbeing People said: "These issues can be tackled effectively not only by education through government schemes and the NHS but also by employers, who have a role to play in helping improve the health and well-being of its workers."
McGannan said: "There is a growing body of evidence that shows that the financial benefits enjoyed by organisations that implement wellbeing programmes include reduced sickness absence, improved productivity and reduced staff turnover.
"Health is the responsibility of every business and employers will benefit from improving the health of the people that work for them."
Brett Hill, commercial director at The Health Insurance Group, said: "The report shows just how much more needs to be done to get the nation's workers healthier and happier."
Hill added: "Adults should aim to be active for approximately 150 minutes a week and there are quite a lot of us doing this (38 per cent of males, 31 per cent females) as we know physical activity is important in the management and prevention of many common diseases.
"There is a stubborn hardcore who do little or nothing in the way of activity, placing them at risk of serious ill health later in life."
Hill said: "Drinking regularly just above the lower risk guidelines increases the risk of ill health significantly.
"And while heavy drinking has declined in recent years it seems too many of us are now reaching for the alcohol with more frequency - a sign of more pressured times, perhaps?"
