Processed meat apart, they are just getting a different diet - all carbohydrate and sugar, and a better one - all year round access to a huge variety of fruit and vegetables.

Take half the carbohydrate and two thirds the processed white flour/sugar out of the child's diet and you'll see a huge difference. Carbs make fat that is stored for use later, ordinary fats are used fairly rapidly. When you store all that fat and then don't use it, it's going to stay where it is, in the fat deposits on the stomach, the hips, the bum and thighs.
