FAT blokes are also enjoying extra portions in the bedroom — as they get more nookie than thinner men, a study says.
Among sexually active older Brits, tubby fellas were a third more likely than their slim counterparts to have romped in the past week.
They also did it more often — with some experts suggesting they have an excess of confidence to go with the flab.
Those in happier relationships may also be better fed and feel no need to keep weight down, sex gurus claim.
It is believed to be the first to investigate the link between frequency of intercourse and weight.
Researchers found the likelihood of having sex in the past year was the same across all sizes. However, tubbier blokes did it more often.
The study also found overweight women were 16 per cent likelier to have had sex in the previous week.
Lead researcher Dr Lee Smith told journal PLOS One: “I believe the observed association is owing to spouses in satisfying relationships relaxing their efforts to maintain their weight because they are no longer motivated to attract a mate.”
“Therefore, those who are overweight are more likely to be in a happy and satisfying relationship and…more likely to engage in frequent sexual activity.”
Psychotherapist Phillip Hodson added: “Some women feel attracted to all that protective bulk. Well-fed men also have an excess of energy to burn.”
