Ketones, made when the body burns fat because it lacks insulin.

  1. Ketones, from burning fat for fuel ✔
  2. Vitamins, from too much fruit
  3. Calcium, from too much milk

Why: Without enough insulin, cells can't use sugar, so the body burns fat and makes ketones. High ketones cause DKA, a medical emergency. It's most common in type 1 but can happen in type 2.

Huh, didn't know that: Ketone test kits are sold over the counter so you can check at home.
