During a Crohn's disease flare, the goal is to minimize irritation of the inflamed bowel and ensure adequate nutrition while healing occurs. Bowel rest reduces gut activity and inflammation, and in more severe cases total parenteral nutrition (TPN) may be used so the body still gets calories and protein without requiring the gut to process food. A low-residue diet supports this by minimizing fiber and other irritants, which decreases stool volume and mechanical stress on the bowel.

High-fiber foods would increase stool bulk and may worsen symptoms during a flare. A gluten-free diet isn’t universally indicated unless there’s a diagnosed gluten sensitivity or celiac disease. Caffeine can stimulate the gut and often worsen diarrhea and cramping, so it’s generally avoided in active flares.

So the best description of flare management is bowel rest with nutrition support as needed (including TPN) and a low-residue diet to reduce bowel workload.
