New Research shows that a total of 700,000 U.K. children are now clinically obese leading to a massive increase of diabetes and heart disease in youngsters. The main causes are lack of exercise and bad diet. Not surprising really, as the majority of today's children tend to spend all their leisure time either watching t.v. or on their computers. Also Jamie Oliver's healthier school meals have backfired in some schools, as many children prefer to tuck into their junk food laden lunchboxes rather than eat the healthy school meals on offer.
