Type 1 Diabetes: How to Bolus for Potato Chips with Jenny and Scott

Understanding Potato Chips and Carbs

• 💡 The episode focuses on bolusing for potato chips, a popular junk food identified by AI and Google searches.
• 📌 A general rule of thumb is that a single potato chip contains approximately 1 gram of carbohydrate, while tortilla chips contain 2-3 grams.
• 🍟 For Lays Classic Potato Chips, a serving of about 15 chips contains 15 grams of carbohydrates and 10 grams of fat.

Challenges in Bolusing for Chips

• ⚠️ The primary challenge with potato chips is their high palatability, making it easy to consume more than the standard serving size (the "once you pop, you can't stop" phenomenon).
• 🧠 The fat content in potato chips (over 50% of calories) acts as a stabilizer, slowing digestion and potentially causing blood sugar to remain elevated for longer.
• 📈 If not pre-bolused correctly, chips can lead to a rapid rise in blood sugar followed by a lingering effect due to the fat content.

The Mealbolt Strategy for Chips

• 🎯 The Mealbolt strategy (Measure, Evaluate, Add, Layer, Build, Offset, Look, Tweak) is introduced as a framework for bolusing.
• ⚡ For potato chips, it's generally advised not to pre-bolus due to their fast digestion, but rather to bolus for the carbs and be prepared for the fat's lingering effect.
• 📊 Considerations for activity levels, time of day, and sensitivity are important, as activity might help mitigate the rise from chips, but the fat content can still cause a delayed effect.

Practical Bolusing Tips

• ⚖️ Be honest about consumption; if you plan to eat more than 15 chips, adjust your insulin dose accordingly.
• 🥑 Some brands, like Boulder chips made with avocado oil, are mentioned as a potentially better alternative due to the oil used.
• 🔍 The importance of looking at the CGM post-meal to observe spikes and lingering effects is crucial for tweaking future boluses.

The Mealbolt Framework Explained

• 📝 The Mealbolt formula involves measuring carbs, protein, and fat; evaluating current blood sugar, insulin on board, and activity; adding base units based on insulin-to-carb ratio; layering corrections for high blood sugar; building the bolus shape (e.g., extended or combo bolus for fatty/processed foods); offsetting timing for pre-bolusing; looking at CGM data for immediate and delayed effects; and tweaking for the next time.
• 💡 While not every step is explicitly stated in every conversation, the Mealbolt framework guides the discussion on how to approach bolusing for specific foods like potato chips.
