Question

Is it safe to eat 800 calories a day?

When trying to lose weight is eating 800 calories a day safe?

Answer 1

For a woman it's certainly bad to eat less than 1,200 calories per day so eating only 800 calories per day could be dangerous to your health and increase your risk for gallstones and heart problems.

That would go for men as well I would not go below 1,000 calories per day unless directed to do so by a doctor.
