Turmeric does not meaningfully break a fast. A teaspoon of ground turmeric has about 9 calories, and a curcumin capsule close to none. Golden milk is the exception: made with milk and honey, it is a small meal.

| Breaks a weight-loss fast? | No |
| Breaks ketosis? | No |
| Breaks autophagy? | Unlikely |
| Insulin impact | Negligible |
Used as a spice in hot water or tea, turmeric adds a few calories at most, far too little to raise insulin or end a fast. Capsules contain curcumin extract and filler measured in milligrams.
Curcumin is poorly absorbed, so supplements often add black pepper extract or fat. Some capsules are oil-based softgels with a few calories. High-dose supplements can upset the stomach and interact with blood thinners; ask a pharmacist if you take any.
A pinch or a teaspoon in hot water or tea is fine during a fast. Take capsules as labeled, ideally with your first meal if they bother your stomach.
