Pizza is the single most-asked-about food in diabetes communities. Here's how to actually have it.

The carb math

Slice (1/8 of 14")	Net carbs
Thin crust	22–26g
Regular crust	30–35g
Deep dish	40–50g
Stuffed crust	45g+
Cauliflower crust (good brand)	8–12g
Fathead/keto crust	3–5g

Best crust choices (commercial)

**Real Good Foods Cauliflower** — 5g net carbs per slice
**Caulipower** — 8g net carbs per slice
**Outer Aisle cauliflower thins** — 2g net carbs per "slice"
**Cappello's almond-flour crust** — 4g net carbs per slice

Best chain pizza order

**Thin crust** (always)
Light cheese, extra veggies
High-fat toppings (pepperoni, sausage, extra cheese, olives, anchovies)
**2 slices max** — supplement with salad

Smart pairings to flatten the spike

Eat a large salad with vinegar dressing first
Have a glass of water with apple cider vinegar 10 min before
Walk 10–15 minutes immediately after eating
Pair with a small serving of nuts for additional fat

The "pizza tail" effect for type 1s

Pizza causes delayed glucose rises 3–5 hours after eating due to fat slowing carb absorption. Many type 1s use extended-wave boluses to cover this.

Make-at-home wins

Fathead dough crust (mozzarella + cream cheese + almond flour)
Cauliflower crust (DIY or store-bought)
Chicken-crust pizza
Portobello mushroom "pizzas"

These cut carbs by 80%+ and most people can't tell after the second slice.
