London: Like a female body is classified largely into four body shapes, scientists have come up with geometric shapes to describes males.

While a female structure is divided into banana, pear, apple and hourglass shapes, male body has been classified into triangle, rectangle, oval and linear.

If you are a triangle, with broad shoulders and a tapered waist like footballer David Beckham, your figure will hold no fears. Indeed, you may find yourself hogging the mirror for rather too long.

However, most men fall into the chunkier rectangular category, like Britain's Got Talent judge Michael McIntyre. Beware of creeping weight gain, say the experts.

Oval-shaped men, like apple-shaped women, carry their weight around the mid-section. Think roly-poly comic Johnny Vegas.

Linear Man, as epitomised by beanpole comedy writer Stephen Merchant, aged 36, is thin with narrow shoulders, waist and hips.

"Women have for many years been categorised by shape but nothing similar had been applied to men. Four distinct shapes kept reoccurring in the survey," a newspaper quoted nutritionist Linda O'Byrne, who helped to compile the research linked to dieting, as saying.
