SHOW NOTES: You already know you should pre-bolus. Your endocrinologist has told you. Every diabetes educator has told you. And you still dose with your first bite, same as the rest of us. Neil Greathouse, who has lived with type 1 diabetes since 1992, kicks off The Head Start, an eight-week challenge all about pre-bolusing your insulin, by admitting he doesn't do it perfectly either.

Here is the reframe that changes everything: pre-bolusing is not a knowledge problem. Almost nobody with type 1 needs it explained. It's a fear problem, a forgetting problem, and a "the food came late one time" problem. Over the next eight weeks, we fix it gently, using dinner as our meal, with about 1,500 people doing this challenge worldwide.

In this episode:

  • Why pre-bolusing is the most-ignored advice in type 1 diabetes
  • The real reason we don't do it, and why it isn't discipline
  • The one stat that proves you're not the only one (more than 1 in 4 meals gets a late or missed bolus)
  • Why we're building the whole challenge around dinner

This Week's Challenge: Change nothing. Just notice your blood sugar two hours after dinner. We're taking a "before" picture before we change a thing.
