I’m a dietitian – how long zombies could live eating only brains revealed and why their diet may spark slow walk & talk

A DIETITIAN has revealed how long zombies could survive on an all-brain diet – and how it would make them behave.

While the Halloween favorites are far from real, researchers applied science to their typical behaviors while analyzing their diets.

Dietitian Grace Derocha told the Washington Post how zombies largely follow a keto diet – as eating only brains contains very few carbohydrates.

Brains are made up of 60 per cent fat and 40 per cent protein, meaning zombies could lack energy by not eating anything else.

The creatures could also notice “keto flu” symptoms, a common condition that affects people who need to consume more carbs, Derocha explained.

She said: “They’re moaning, they’re very slowly walking around in a daze with brain fog.”

Other than this, however, brains appear to be very healthy.

The organ is 80 per cent water weight, meaning it’s a good source of fluids and contains plenty of nutrients to energize and strengthen bones and connective tissue.

But a brain-only diet can’t be sustained forever.

Derocha explained they lack key nutrients, vitamins, and minerals.

Meanwhile, Timothy Verstynen, a Carnegie Mellon cognitive scientist, suggested zombies might have lost key functions in their decaying brains, which would then impact their behavior, movement, and speech.

He told the Washington Post: “They may be constantly attacking because the…
