  • Is It OK to Dose Insulin After a Meal for Kids? | ISPAD Guidelines, T1D
    2026/08/21

    Here's the permission slip every T1D parent needs: with a young child, dosing during or after the meal is not cheating. It's not failing at pre-bolusing. It is, in plain black and white in the international pediatric diabetes guidelines, an okay thing to do. Parents, exhale.

    The people who write the rules for kids with type 1, ISPAD, carve out a specific exception for infants and toddlers who are unreliable eaters. It's not a loophole, it's the guidance, built on the real risk of lows in tiny bodies. And the other direction is backed too, when you can dose before the meal, kids hit a lower glucose peak and a lower A1C, with no extra hypoglycemia. Before when you can, after when you can't, and both are in the book.

    In this episode:

    • Why dosing after the meal is allowed for young kids (per ISPAD)
    • The reason the guidelines built in the toddler exception
    • The research supporting pre-meal dosing when it's safe
    • Letting go of the guilt you don't need to carry

    This Week's Challenge: For the parents, let go of one piece of guilt. If you've been forcing an early dose and stressing about lows, try dosing right after the meal this week for what they actually ate, and bring it to your care team.

  • Pre-Bolusing for a Picky Toddler with Type 1 Diabetes | Combo Bolus
    2026/08/19

    Your toddler asked for the macaroni, then looked at it like you served packing peanuts and demanded the one other food in the house, and you've got insulin on board for a meal that just got canceled. This episode is for the parents dosing into pure chaos.

    Neil pulls the playbook straight from the pediatric diabetes guidelines. The split: dose for the part you're sure they'll eat, then give the rest after. ISPAD recommends a combo or dual-wave bolus for uncertain eaters, part before, the rest over 20 to 40 minutes once you see what got eaten. And there's good news in the research, a systematic review found that pre-meal dosing, when you can pull it off, lowered the after-meal peak and even lowered A1C, with no increase in lows. Keep fast carbs on the table, always.

    In this episode:

    • The split-dose strategy for a kid who might not finish
    • The ISPAD combo/dual-wave bolus for uncertain eaters
    • The research: pre-meal dosing lowered peaks and A1C with no extra lows
    • Why fast carbs on the table are non-negotiable with little ones

    This Week's Challenge: For the parents, try the split on one unpredictable meal. Dose for what you're sure they'll eat, then top up after. Notice how much less terrifying that is.

  • Pre-Bolusing & Why Your Tech Can't Save You Alone // Natalie, Bellini, DNP
    2026/08/17

    She stopped counting years with type 1 a long time ago. Natalie Bellini counts days... more than 20,000 of them. This week Neil finally gets his dream guest: Natalie Bellini, DNP, FNP-BC, BC-ADM, CDCES, nurse practitioner, assistant professor of medicine at Case Western Reserve University, and program director for diabetes technology at University Hospitals in Cleveland. She has lived with type 1 diabetes for 55+ years, her husband has it too, and she still uses the word pre-bolus a dozen times a day with the people she treats.

    This is the pre-bolusing conversation for the rest of us. Natalie breaks down why the two hours after each meal (that's six hours of your day) quietly decide your time in range, why even the best automated insulin delivery system can't catch a meal it never saw coming, and the baby-step way to start pre-bolusing when fear of lows has kept you on the sidelines. Then she gets real about the parts of care nobody talks about: meeting patients where they are, why having diabetes doesn't automatically make you a better clinician, and the screening mission she helped build with her own family's blood work.

    In this episode:

    • What pre-bolusing actually is in plain English... your carbs are fast, your "rapid-acting" insulin is not, and timing is how you stop the chase
    • Why post-meal spikes are 25% of your number, and where pre-bolusing lands on Natalie's top-four list for a 20-minute appointment
    • The baby-step method: pick one meal (breakfast is the easy win), start with 10 minutes, split the dose, treat the high first, and know when NOT to pre-bolus
    • "Your diabetes is a two-year-old"... why AID pumps still need you to announce meals, and what a missed pre-bolus looks like on your CGM
    • The rookie mistake that makes people quit (too much insulin up front, usually at a restaurant), and how little swings beat big ones
    • Her screening passion: three blood tests at ages 2, 6, and 10 can catch 80% of kids on the path to type 1 before DKA ever happens
    • True or False, a Diabetes Confession Booth for the ages (she borrowed her husband's insulin pump at dinner... it works), and a tie of the Fastest Five Minutes world record (29 answers!)

    This Week's Challenge: Pre-bolus one meal. Pick a day you're not working, keep carbs within reach, treat the high first, and start with just a little insulin up front... even five minutes early counts. Trust the behavior, then watch the curve change. Slow and steady wins this race.

  • Pre-Bolusing and Still Spiking? Check Your Carb Count | Type 1 Diabetes
    2026/08/14

    You pre-bolus. You give it the 15 minutes. You watch the arrow. And you're still spiking. Don't throw out the challenge, that spike is a clue. Neil puts on the detective hat, because timing is huge, but it isn't the only dial on the dashboard.

    If your timing's perfect and you're still climbing, the amount may be the problem, and the most common culprit is the carb count. A study by Brazeau found that adults with type 1, averaging 21 years of experience, were off by about 15 grams of carb per meal, roughly 21% of the plate, and underestimated 63% of the time. Neil walks through the other usual suspects too, fat and protein, stress, hormones, and exercise, and how to troubleshoot with your care team.

    In this episode:

    • Why perfect timing doesn't always fix a spike
    • The Brazeau study: even veterans miss carb counts by about 15 grams
    • The other suspects: fat, protein, stress, hormones, exercise
    • How to play detective on one meal without changing doses solo

    This Week's Challenge: If you're pre-bolusing well and still spiking, play detective on one meal. Weigh or honestly eyeball the carbs, see if the count was off, and bring what you find to your care team.

  • Fiasp, Lyumjev & Afrezza: Do You Still Need to Pre-Bolus? | T1D
    2026/08/12

    "Neil, I use Fiasp, or Lyumjev, or Afrezza, do I even have to wait?" Great question, and this episode gets genuinely nerdy about the answer. Fiasp and Lyumjev are ultra-rapid analogs, built with ingredients (niacinamide in Fiasp, citrate and treprostinil in Lyumjev) that speed up subcutaneous absorption. Afrezza is inhaled Technosphere insulin with a Tmax around 12 to 15 minutes that delivers more than half its effect in the first hour, versus about 10% for regular rapid insulin.

    So the fast insulins shrink the pre-bolus window. But here's the honest part: most people aren't on them, and standard rapid insulins like Humalog and Novolog are excellent. The whole point of the challenge, timing, is the great equalizer. Know your insulin, and you know how big your head start should be.

    In this episode:

    • The pharmacology of Fiasp, Lyumjev, and Afrezza, in plain English
    • Why inhaled Technosphere insulin peaks in about 12 minutes
    • Why the fast insulins shrink, but don't erase, the pre-bolus window
    • Why standard rapid insulins still run beautiful numbers

    This Week's Challenge: Know your insulin. Look up, or ask your care team, roughly how fast the insulin you take starts working. That one fact tells you how big your head start should be.

  • Do You Still Pre-Bolus on a Closed-Loop Pump? | Control-IQ, Omnipod 5
    2026/08/10

    If you're on a closed-loop system, Control-IQ, Omnipod 5, or Loop, you've probably wondered whether the algorithm means you're off the hook for pre-bolusing. Neil has to be the one to tell you: you still do it. These systems are an incredible co-pilot, but they're not a self-driving car you can nap in.

    Here's the reason, with a real number. In Omnipod 5 data, when people skipped the meal bolus, the algorithm poured in about 16% of their total daily insulin over the four hours after the meal trying to catch up, and it still couldn't stop the spike. These hybrid closed-loop, or automated insulin delivery (AID), systems are reactive, they respond after glucose rises. The guidance to bolus 10 to 15 minutes early is published, not opinion.

    In this episode:

    • Why closed-loop pumps still need you to pre-bolus your meals
    • The Omnipod data: the algorithm used ~16% of daily insulin and still spiked
    • Why AID systems are reactive, not predictive
    • Why bolusing TOO early can backfire on a closed loop

    This Week's Challenge: If you're on a closed-loop system, give your meal dose about 10 to 15 minutes before dinner and watch how your system rides along. Compare it to dosing at your first bite.

  • Missed and Late Insulin Boluses: What to Do | Type 1 Diabetes
    2026/08/07

    Some nights you do everything right and it still goes sideways. The dinner party, the cookout with the moving-target food, the night you're so fried you only remember to bolus while scraping the plate. This is permission day. Missing doesn't mean you failed the challenge, it means you have a life with other humans in it.

    Neil gives the real-life moves for the messy nights, and grounds them in data. Remember that 27% of meals get a late or missed bolus? Here's the kicker: young people with type 1 who never miss their boluses were 24.5 times more likely to be in excellent control than poor control. So catching a forgotten dose and taking it late isn't damage control, it's the single biggest difference-maker on the board. A late bolus beats a no bolus every time.

    In this episode:

    • Real-life moves for social meals, cookouts, and buffets
    • What to do the night you completely forget to bolus
    • Why kids who never miss boluses were 24.5x more likely to be in great control
    • Why consistency, not perfection, is the whole secret

    This Week's Challenge: Have one of those messy nights, and practice not spiraling. Miss it, catch it, move on. Prove to yourself one imperfect night doesn't torch the whole thing.

  • Why Pizza Spikes Your Blood Sugar at Midnight | Fat, Protein & T1D
    2026/08/05

    Some meals spike you and move on. Pizza spikes you, waves goodbye, and comes back four hours later like a horror-movie villain. If you've ever been 110 at bedtime and 260 at midnight, this episode explains the ambush, and it's backed by real research.

    A 2013 study led by Howard Wolpert in Diabetes Care fed people the same carbs, but one meal was high in fat. The high-fat meal required about 42% more insulin over the following five to ten hours and drove hyperglycemia for hours, even with extra insulin. The reason is that fat slows gastric emptying, so glucose trickles out over hours instead of arriving at once. Neil explains the tools that help, extended, combo, and dual-wave boluses, and why carb-counting math alone can't cover pizza.

    In this episode:

    • Why high-fat meals like pizza cause a delayed, second-wave spike
    • The Wolpert study: 42% more insulin for a high-fat meal, same carbs
    • How fat slows gastric emptying and stretches out your glucose rise
    • Extended, combo, and dual-wave boluses, explained simply

    This Week's Challenge: Next time you eat a high-fat meal, just watch what happens two, three, four hours later. Witness the second wave, then ask your care team if an extended bolus makes sense for you.
