Intermittent Fasting Bone Broth Soup

Letting bone broth simmer with carrot, celery, and onion for nearly an hour draws out a deep, savory flavor that a quick fifteen-minute broth just can't match.

Because it's mostly liquid with a modest amount of vegetables, this soup is often chosen as something light to sip during a fasting window without introducing much in the way of solid food. Fresh thyme and a handful of spinach or kale stirred in near the end round out the flavor and add a small dose of greens.

Let it simmer low and slow rather than at a rolling boil — this keeps the broth clear and the vegetables from turning mushy by the end.
