How many days can you survive without food?

A friend of mine’s mother was in hospice and lived 19 days without food or water. She wasn’t hooked up to IV’s. I would not think going that long would be possible.

People in retirement homes who decide to starve to death usually last no longer than 6 weeks.

DAYS?
Maybe six hours. If I don’t snack I would surely die.

I’ve always heard the 3–3-3 rule – 3 minutes without air, 3 days without water, 3 weeks without food. YMMV.

If I want to get technical about it, I once survived 2 months without food. But I was on IV nutrition.

Three weeks is the often quoted figure.
The real trick is starting to eat again afterwards without killing yourself from refeed syndrome.

“Generally, it appears as though humans can survive without any food for 30–40 days, as long as they are properly hydrated. Severe symptoms of starvation begin around 35–40 days, and as highlighted by the hunger strikers of the Maze Prison in Belfast in the 1980s, death can occur at around 45 to 61 days.”
