That might be true with adults, but the diet of children is more difficult to control. I am well aware of the benefits of low carb diets, but keeping children on a strict diet is often difficult at best.
Diabetes runs in my husband’s family and none of them were over weight, all naturally thin and weight conscious.
Monitoring has always been essential, in fact the evidence in the past ten years or more was to increase monitoring.
I was type II when I was pregnant. I did well, but I also monitored. To deny monitoring to children is conscionable.
