Doctors have warned the 'We Made You' rapper - who has recently lost 28lbs by cutting alcohol and fatty foods from his diet - he could be putting his life at risk or become anaemic if he keeps on the diet while touring.
US based doctor Morris Missler told Britain's Daily Star Sunday newspaper: "Even without a wildly energetic and adrenalin-charged job, crash dieters risk heart attacks and strokes, liver and kidney failure and most certainly death in extreme cases.
"Anaemia could be caused by iron deficiency. Crash dieters are usually deficient in vitamin B12, potassium and sodium. The last two play an important part in regulating the way your heart beats. If their levels become too low, he could suffer a heart attack."
The 36-year-old rapper - real name Marshall Mathers - has, however, said he will only be eating diet-friendly foods during his next tour and has altered his rider requests to suit his healthy new lifestyle.
A source close to the star said: "He used to live off fried chicken, fries, burgers and his real favourite, drumsticks. Now he's eating only grilled meats and fish, fruit and vegetables, but no refined carbs. His riders are unrecognisable from those of four years ago."
