Juicebox Podcast: Type 1 Diabetes
Episode #1740 Bolus 4 – Potato Chips
Host: Scott Benner
Guest: Jenny Smith
Date: January 17, 2026
Overview
This episode continues the Bolus 4 series, where Scott and Jenny discuss practical strategies for bolusing insulin for specific foods—with today’s focus on Lay’s classic potato chips. The conversation is light and accessible, centering on real-life challenges, snack food temptations, and step-by-step considerations for people with diabetes striving to live well and “be bold with insulin.”
Key Discussion Points & Insights
1. Introducing the Meal Bolt Approach
- Every Bolus 4 episode uses the “Meal Bolt” roadmap—a structured way to think through mealtime insulin dosing.
- Although the roadmap isn’t always followed point-by-point, it frames every discussion.
Meal Bolt Steps:
- Measure the meal: assess carbs, protein, fat.
- Evaluate yourself: check blood sugar, activity, stress, etc.
- Add base units: calculate using your insulin-to-carb ratio.
- Layer a correction: adjust for out-of-range blood sugars.
- Build bolus shape: decide if you need a standard or extended (combo/square wave) bolus.
- Offset timing: consider pre-bolusing or delayed dosing.
- Look at CGM: review data for future tweaks.
- Tweak for next time: analyze what worked/what didn’t for future improvements.

2. Potato Chips: Nutritional Breakdown
- Today's focus is on Lay’s Classic Potato Chips (yellow bag, thin, no ridges).
- Nutrition per serving (15 chips):
- Total fat: 10g (1.5g saturated)
- Carbs: 15g (1g fiber)
- Sodium: 170mg
- Key insight: Roughly 1g carb per chip—a “rule of thumb” if you lack a label.
- Tortilla chips: denser, 2-3g carb per chip.
[03:29]
Jenny: “In general, a potato chip is about a gram of carb per chip, no matter what brand... For tortilla chips, sometimes 2 or 3 grams.”
[03:36]
3. The “Portion Creep” Challenge
- Realistically, few people eat only 15 chips—serving sizes are often exceeded, especially with open bags or party settings.
- Acknowledges the difficulty in resisting more chips, referencing the Pringles catchphrase: “Once you pop, you can’t stop.”
[04:23]
Scott: “What’s the biggest problem with chips? It’s that you don’t eat 15 chips, right?”
[04:06]
Pro tip: Watch for “blind bolusing”—guessing at numbers like 45 carbs because it "looks about right," instead of counting.
Scott: “Arden’s give up number is 45…Yesterday and I thought, this is not 45, this is probably more.”
[12:16]
4. Impact of Fat and Pre-Bolus Importance
- Potato chips are quite fatty—over 50% of calories from fat. Fat slows digestion and leads to a more drawn-out glucose rise.
- Fat can “stabilize” the glucose rise, but may cause lingering post-meal highs.
Activity Considerations:
- Chips might buffer glucose if you’re active, but usually chips are eaten in sedentary settings.
- If you’re going to be active, chips may prevent lows to some degree, but not recommended as a sports snack.
[08:20]
Jenny: “That’s more than 50% [of calories] coming from fat, which means they’re going to be more, let’s call it, stabilizing.”
[08:20]
5. Pre-Bolusing is Crucial
- Chips digest quickly due to their processed nature—glucose hits fast. Without pre-bolusing, expect an early spike, then lingering high due to fat.
- Pre-bolus if at all possible for better post-snack control.
Scott: “You don’t pre-bolus a potato chip, it’s going to grab you pretty quickly and you’re going to be fighting with it then for hours afterwards.”
[09:25]
Jenny: “The more processed something is…we’re not talking about this being a baked potato…We’re talking about something that’s like processed potato flakes maybe. Yes, it started out as a potato at some point…and now we have something that’s a chip.”
[10:02]
6. Honesty in Carbohydrate Counting
- It’s tempting to underestimate or “round” carb estimates with snacks.
- Visual guesstimates (like “about 45g of chips”) often lead to insulin errors.
- Recommendation: Be honest and try to count/estimate as accurately as possible.
Scott: “I know people are like, ‘look, I don’t count my carbs, but like, you gotta guess, you gotta guess, right?’”
[12:16]
7. Potato Chips & Bolusing in the Real World
- Activity, time of day, and personal insulin sensitivity all matter when bolusing for chips.
- Each eating context is unique: party, sitting at home, picnic, pairing with other food or drink (like beer).
- Layer in corrections if starting above target BG. For example, if at 150 mg/dL before eating, add the correction alongside your food bolus.
- Watch for delayed BG response due to both the rapid carb absorption and the sustaining effect of fat.
- Use CGM data to tweak strategy next time.

8. Personal Anecdotes & Fun Moments
-
Scott shares a story about finally eating salsa and tomato (something he’d previously never tried), debuting his personal adventure into “new food” territory—on a tortilla chip, of course!
[05:18] -
Shared laughter around favorite chip brands, with Jenny mentioning Boulder brand (made with avocado oil) as her recent choice, praising them for good crunch and substance.
Jenny: “I did. They…crunched and they had like substance to them. So yes, avocado oil or...olive oil as well.”
[13:42]
Notable Quotes & Memorable Moments
-
Scott: “You process the potato. That makes it more difficult for your body to process. You add a bunch of oil, it slows down your digestion, makes it even more difficult again.”
[11:17] -
Jenny (on chip portioning): “It’s very easy to keep grabbing.”
[04:49] -
Scott (on BG curve missteps): “That bolus missed by four units, I think. And that’s a fairly significant amount.”
[12:16] -
Jenny: “I am not encouraging people to eat Lay’s chips to be stable in exercise!”
