nonsense....if sugar ( or any other food for that matter) was ‘the cause’ of obesity then people would have been fat for thousands of years. Obesity is caused by lack of exercise....these obese children do not go outside to play (for lots of reasons), the eat generally crappy diets, and no one at home is interested in changing anything.
Sugar is not the enemy.
Can’t just be the food. There are people (I’m one of them) who just won’t get fat, no matter how much they eat.
