Can you get a stroke from eating less?

No and no. A stoke occurs when blood flow is cut off to a part of the brain. a stroke can happen with a blood clot forms in an artery leading to the brain. A clot can be due to plaque build up which is associated with a chronically bad diet and being overweight, but it can happen due to a weakness in the wall of an artery that no one even knows is there.

that would be neither
