According to a new report out of Britain, the tall reality TV star is living off just 400 calories per day to achieve her thin physique and it has friends and family worried about her health.
"Khloe's doing morning fasting and doesn't eat a single thing until around 2pm," a source told Heat magazine.
"She only has a small piece of chicken or a can of tuna and steamed veggies for lunch, snacking on celery until dinner when she has a protein shake and more vegetables," according to the report.
The Keeping Up With The Kardashians star hasn't kept her shocking new diet a secret and her shattered self-esteem from the breakup with Odom is to blame.
"Everyone in her life is begging her to eat more, but Khloe is refusing," the source claims.
"She's not in a good place. Her self-esteem took such a hit when she broke up with Lamar."
Dietician Chloe Phillips, who has not treated Kardashian, weighed in on the matter pointing out obvious health concerns.
"The human body will struggle on 800 calories, let alone half of this," she said.
Such a low intake of nutrients could lead to nausea, heart complications, gallstones and of course — weight gain when regular eating resumes.
