Do you have any others to propose?
Think Like a Pancreas by Gary Scheiner is a good one.
For those of us with cgm, Sugar Surfing by Stephen Ponder and Beyond Fingersticks by William Lee Dubois are helpful.
They're all T1, GS and SP are also endos, and WLD is a dsn, so they've all dealt with it personally and professionally.
I think they are less emphatic about things than Bernstein and give T1s more options than he does. SP has a chapter on how to insulin-stack for burritos, which would probably have Dr B fainting!
I accept that moderating carb intake is a good line - I do it myself, most meals are around 50 to 80g (although many would say that's too much) - but he just goes too far.
He's a product of his background. Had complications because of the primitive treatment methods in his youth, recovered because of being able to test and modify diet.
What I feel he's missing is that in this day and age, newly dx'd have from the start modern bg testing methods, better insulins, some have cgm, so it's perfectly possible to keep an eye on things from day one in a way which he wasn't able to, figure out which carb/bolus combinations work to stay in range, without ruling out an entire macro group.
There's been quite a few posts on this site by T1s who've gone down the Bernstein route. But they've then come back after a few months to say they actually would like to eat carbs after all. We're not talking crazy amounts here, not sugared popcorn at the movies, they just want to nip in to a local Italian cafe and have a 50g panini. Yet they feel guilty about it, because Bernstein says no. Even though a 50g panini with a bit of careful pre-bolusing is perfectly manageable with modern methods.
His book has a large section at the start with quotes from clients, enthusing about his methods. I'd like to ask them how they feel about doing such a restrictive diet for decades.
