Eat them raw and sliced thin — raw Jerusalem artichokes have the same calorie count as cooked but retain more of their inulin fiber, which helps you feel fuller on fewer calories.
- 2.
Watch your portion size with roasted preparations — added oil can easily double or triple the calorie content per serving compared to eating them raw.
- 3.
Use Jerusalem artichokes as a lower-calorie swap for potatoes in salads; you get a similar hearty texture with slightly fewer calories and more fiber.
- 4.
Pairing them with a protein source (like grilled chicken or eggs) helps slow digestion and keeps total meal calories in check while maximizing satiety.

A 1-cup sliced raw serving (~134g, ~98 calories) is a filling, high-volume snack or side dish that fits easily into most calorie targets.
