International health insurance customers might want to book an appointment with their doctor if they are at all concerned about their weight.
Among women, a waist size of 32 inches or above is an indication or being overweight, while men should avoid having a waist of 37 inches or above.
However, research from safefood has found that just 38 per cent of people are aware that they are overweight or obese.
This is despite the fact that 61 per cent of those surveyed were identified as overweight.
Martin Higgins, chief executive of the group, commented: "We need to realise what we think of as 'normal' has shifted over the past 20 years; almost 60 per cent of those we surveyed may feel they are a healthy weight but many of those are in fact overweight.
"We must all take a hard look at the facts, measure and know our waist and do something about it today."
