Together, the pluses of sexual benefits and minuses of the energetic costs of being beefy may even out in the end, explaining why men of all shapes and sizes thrive, Lassek contends. Skinny men have new reason to celebrate. Yet no one had examined both the positives and negatives of big muscles in a single population, says Lassek, who analysed data from more than men, aged 18 to 49, who participated in the National Health and Nutrition Examination Survey , between and The study also showed that more muscled men tended to lose their virginity at a younger age, compared to skinny men. A larger appetite may not seem like a cost in modern western societies, with a restaurant or grocer on every corner.

Hunks get more sex, but there's a price to pay
New coronavirus may be much more contagious than initially thought What are the symptoms of the new coronavirus and how deadly is it? Many other studies have shown that women tend to prefer more toned men , and muscle-bound men tend to have more sexual partners than slender men, when other factors are controlled for. Beefcakes may be able to attract women by rippling their muscles, but the downside of all that brawn is a poor immune system and an increased appetite, a new study finds. Compared to skinnies, muscular men also tended to produce fewer infection-fighting white blood cells and less of an important immune molecule called C-reactive protein, which helps destroy pathogens. Such evolutionary costs could explain why males of our species do not all look like He-Man, according to William Lassek, an evolutionary psychologist at the University of Pittsburgh , Pennsylvania, who led the new study. The beefier the man — measured by total fat-free mass, or arm and leg muscle mass — the more sexual partners he had, Lassek confirmed. Trending Latest Video Free.
