As a TID, not as professional advice or opinion:
Bluntly put, it is horses for courses. We will have individual responses to food which influence what we eat either as T1s or T2s.
And yes, if you have a metabolism which tends to burn through food rather than store it, and have the capacity, endurance and level of activity and the means (added insulin) to tolerate a high carb diet then that will suit you ....until it doesn't so much.
Why?
What happens if you are unfortunate to be laid up with an injury or illness or cannot maintain a certain activity level?
Yep, your insulin sensitivity drops and the type of carbs you liked so much or the quantities you eat, now put BSLs up too much. Or in trying to keep up the active days you eat , have even more insulin and then you realise that you are gaining weight. Down goes the insulin sensitivity etc.
Yes, your metabolic type in this supposed temporarily infirm state may allow you more food than some diabetic, T1, in the similar situation who has a slower metabolism (or who has an undiagnosed under-active thyroid for example).
High carb might be perfectly OK for your metabolism type but saying that all T1s can eat what they like and just adjust insulin is simplistic. Life is more complicated than that. And naturally you are talking about now and the years before, not about in 20 years time. Some of the T1s you are posting to are that 20 years etc older, their metabolism, activity level etc will have altered somewhat. They cannot get away with as much carb and size of meal, or not without gaining too much weight and its attendant problems.. And I am writing about my experience from ages 13 to 65.
And saying that, as an example "I can eat anything I want" like a badge of defiance over this condition is all very well but not actually helpful to those who find as T1s they cannot do that.
So other diets may suit some T1s better whether young or older , low carb high fat amongst them and that causes some restrictions but as those that thrive on such diets report, hunger is not the problem as it was on higher carb diets, hypos are less common or severe.
And have those putting in unit after unit of insulin, as I have done in the long past, thought about what happens at higher levels of insulin in their blood.?
Yes you say the metabolism of T2s is different but it may be worth sparing a thought about at what level of insulin do troubles associated with hyperinsulinaemia start? I profess I do not have a clue, the levels may not be comparable with T2s but perhaps someone knows.
The work of Feinman, Berstein and others that T2s in particular need to regulate their carb intake is so obvious it was almost a certainty that someone would oppose it - like previously the ADA, still some dietitians and, lest we forget, the food industry.
But the obvious also applies to some degree to all diabetics. Yes, T1s have fruit but a plateful of dates or figs?. They know when too much is too much and have to run it off. Is that smart?
And the saving grace for TIs is that they either have learnt to manage their diets and insulin adjustments very well, bit still have lots of hypos, good on them if they can and life is enjoyable, or they rely on CGM to keep them out of trouble, and if that works that is a vast improvement on yesteryear. But it will also tell them when they overdo it with food moreso than before CGM.
Are T1s on higher carb diets and CGM eating anything and everything or does CGM give them pause?
What much is it regulating carbs and dosing accordingly? How much is playing sliding carb scale, dosing up and correction doses later chasing after the bsl s or running it off or treating the impressive hypo?.
