Hi Sampson34,
Yes, there are different ways to manage type 1. Actually though,
carbs are not necessary for
energy, the body can also work perfectly well on very low carb and using mostly fat for energy.
The alternative school of thought, even for kids, is to use low carb (with most of the carbs coming from non-starchy vegetables, full-fat dairy, some nuts) so that blood sugar swings are minimized and less insulin is required. This approach successfully reduces both highs and lows.
