Rather than a suntan, a vegetarian diet will help you score more with the opposite sex, claim scientists. Soaking up the sunrays won`t make you as popular with the opposite sex, as will a healthy glow which a fruit and vegetable diet gives you.

Research shows the English Rose skin of model Rosie Huntington Whiteley gets temperatures rising much faster than the perma-tan of celebs like Kate Price, 32. The study at Bristol University is the first of its kind that establishes a link between sex appeal and a healthier lifestyle.

Excessive suntan can cause "leathering" of the skin – which is a major turn off. Instead a diet of fruit, vegetables and snacks such as cereal and salads – which Willoughby is following currently, can do wonders for your skin.

"We find people prefer the golden effect from diet, rather than the darker effect from the sun," a newspaper quoted Scientist Ian Stephen as saying. A healthy amount of sun plus a vegetable and fruit-rich diet are the key to a beautiful skin. The top fruits for skin care include melons, apricots, and grapefruit. Best veggies are peppers, chillies and spinach.
