1. Eat carrots
Although these pigments in the skin are supposed to be signals of good health, they can be faked.
Taking beta-carotene supplement, for example, will have the same effect.
Beta-carotene is the pigment that gives carrots — and other fruits and vegetables — a strong red/yellow colour.
2. Wear the colour red
Wearing the colour red makes both men and women more attractive to the opposite sex, studies find.
When men wear it, red sends signals of status and dominance to others.
When women wear it, the extra pull on men may have deeper, biological roots.
3. Walk sexy
Attractiveness is about more than just body shape and facial features — it is also about the way people move.
Women who sway their hips while walking increase their perceived attractiveness by 50%, research finds.
Men who walk with swagger in their shoulders more than doubled the perception of their attractiveness.
Swagger involves dipping the shoulders slightly with each step to create a rolling motion.
4. Help other people
But both men and women find those who are altruistic more attractive.
The results come from three studies including over 1,000 people.
People were asked about the behaviours they looked for in a mate.
Some of the suggested behaviours included donating blood and volunteering in a local hospital.
Women were more keen on these altruistic traits in a potential partner.
5. Nod your head
Nodding the head increases attractiveness to others by up to 40% research finds.
Head nodders were rated as both more likeable and more approachable.
It was primarily people’s personality that appeared more attractive when they nodded.
Essentially, nodding makes people more likely to approach you in social interactions.
6. Arch the back (women)
A slight arching of a woman’s back — extending her buttocks outward — makes her more alluring, research finds.
It might help to explain the mystery of why high-heeled shoes are so popular.
They cause women to arch their backs slightly to help them balance.
The study found that only relatively small changes in how much a woman’s back was arched made her look more appealing.
7. Grow a beard (men)
Women judge fully bearded men to be a better bet for long-term relationships, new research finds.
This might be because it makes men look more ‘formidable’.
Certainly, beards make men look older and more aggressive.
Beards are also often judged to make men look like they have higher social status.
However, for short-term relationships, women judge stubble to be most attractive, the new research found.
