Bolus for Lettuce: A Type 1 Diabetes Meal Planning Guide

Understanding Carbs in Lettuce

• 🥬 Lettuce, particularly iceberg and romaine, is primarily water and fiber, containing only about 1-1.5 grams of carbs per fist-sized portion.
• 💡 For practical purposes, counting carbs for plain lettuce leaves on sandwiches or burgers is generally not necessary due to their negligible carb content.
• 🎯 The focus should be on other components of a meal, as lettuce often acts as a delivery system for higher-carb or high-fat ingredients.

Analyzing Restaurant Salads

• 🥗 A Red Robin Little Caesar salad has 8g of carbs, while the Crispy Chicken Tender salad has 60g, with carbs primarily from breading, dressing, and other toppings, not the lettuce.
• ⚠️ The Mighty Caesar salad contains 36g of carbs and 760 calories, highlighting how added ingredients significantly increase nutritional impact.
• 📈 Restaurant meals, even those with lettuce, can be very high in calories, fat, sodium, and carbs, often exceeding home-prepared versions due to larger portions, added sugars in sauces, and pre-meal items like bread.

The Meal Bolt Formula for Bolusing

• 🚀 The episode introduces the Meal Bolt formula (Measure, Evaluate, Add Base Units, Layer Correction, Build Bolus Shape, Offset Timing, Look at CGM, Tweak) as a framework for bolusing for specific foods.
• 📝 Key steps include measuring total carbs, protein, and fat, evaluating current blood sugar and insulin on board, and considering activity and stress levels.
• ⚙️ The formula also covers building the bolus shape (e.g., extended or square wave for slower-digesting meals), offsetting timing for pre-bololising, monitoring CGM trends, and tweaking for future meals.

Lettuce as a Delivery System

• 🍔 Similar to how a baked potato can be a delivery system for butter and sour cream, lettuce serves as a vehicle for other ingredients in meals.
• 🥤 Restaurant beverages like milkshakes can be extremely high in carbs and calories, with a monster-sized shake containing 160g of carbs and 1080 calories.
• 🎯 When experiencing blood sugar spikes after restaurant meals, it's crucial to identify the true culprits, which are rarely the negligible carbs from lettuce itself.
