As we all know, the US has a serious problem with obesity, and a growing problem with childhood obesity. As children advance through the age groups, and football pitches get bigger, players are required to get more mobile. They need a higher level of endurance and physicality, especially at performance level football. At the younger end of the youth football spectrum, little fatties can get away with a sedentary lifestyle, munching into McDonalds morning, noon and night, and generally turning a blind eye to the fitness commitments to the game. Kids, good technically gifted players, around 12/13 years of age are being lost to the games due to a lack of mobility. So, at what age do we introduce a sports specific diet to youngsters? At what age do we get tough with little fatties and take that Butterfinger from their grubby little mitts. At what age do we feel it's appropriate to broach the delicate subject of "the fat kid" with a sensitive parent? The US has already ballooned out of all proportion and the UK is following suit. So, what are the answers? Enlighten me America.
