It is alarming that nowadays some school children practice dieting and these children score lower on intelligence tests and often struggle in school. They  do not  achieve their cognitive potential. The freshness and quality of food matters more than just being full, in particular when children are young and developing.

Similar discoveries were made in an Australian study published in August. It found that while eating healthily can give a boost to intelligence, toddlers on a diet of drinks and sweets were less bright as they got older. By the age of eight the ‘junk food’ children had IQs up to two points lower than their healthy counterparts, according to the researchers from the University of Adelaide.

An American study, published in the Journal of Epidemiology & Community Health in 2010, showed that children who consume junk food such as pizza, chips and biscuits before the age of three may end up having lower IQs than children who ate home-cooked meals with fruit and vegetables. Diets to promote weight loss  are generally divided into four categories: low fat, low carbohydrate, low calorie, and very low calorie.

Those who practice dieting do not have proper awareness of all these differences. They easily become sick and sometimes such sickness is incurable like that of Valeri Lavitina of Russia. She was a beautiful woman. But in going to practice dieting she loses everything of her life. Now she is a wreck.
