Globally acclaimed rap star, 50 Cent has released a diet and fitness book, tracing the beginning of his obsessive interest in working out to the unforgettable 2000 shooting incident, when he was shot nine times and “hurt pretty bad.”

The 37-year-old showed off the benefits of metabolic resistance training (MRT) and a protein-rich diet in his new lifestyle guide, Formula 50, which he says can cause a transformation within just six weeks -

“Follow the instructions I’m giving you here, and you’ll not only look a lot better but feel a whole lot better too,” the rapper, whose real name is Curtis Jackson said.

“You’ll be ready for whatever challenge life throws your way. You might legitimately ask, '’Who are you to preach about fitness? Aren’t you the guy who dropped joints like High All The Time?’”

50 Cent’s plan focuses on accelerating fat loss through short and intense workouts, devising the routines with the help of elite trainer and founder of the Peak Performance gym chain, Joe Dowdell.

Complete meal plans for men and women are also included, courtesy of Layne Norton, a bodybuilder with a doctorate in nutritional sciences from the University of Illinois and Stephanie Wilson, head of nutrition at IMG Academies.

For breakfast they advise a combination of dishes, for example reduced-calorie bread with fruit spread, one ounce of Canadian bacon, two eggs sunny side up and half a cup of honeydew melon; while lunch and dinner menus feature protein heavy staples such as cheeseburgers, Jamaican jerk chicken and beef tenderloin.

“People who start diets fail because they do it like it's a side activity,” he observed. “Next thing you know is you're having things that take all the efforts and the time that you've put into the physical portion of your training right back away. You just put the calories right back in you because you decide to have cupcakes. Why do you have to have cupcakes?”

The rapper shot to fame after the 2003 release of his commercial debut album, Get Rich or Die Tryin, which sold 872,000 copies in the first four days. Lead single, In da Club, broke a Billboard record as the most listened-to song in radio history within a week.

Despite critics deeming his rap star lifestyle as unhealthy, Mr Jackson believes he is the perfect ambassador for staying in shape.

“You might legitimately ask, ‘Who are you to preach about fitness? Aren’t you the guy who dropped joints like High All The Time?' Hardly seems like a fitness anthem..” he continued in the book.

“I don’t drink and I don’t use drugs, and I didn’t back then, either. I put that joint on the first record because I saw artists consistently selling 500,000 with that content.

“I still get a rush off money, but I now realize it can serve a higher purpose: helping others. But unless you are physically strong and mentally tough, you can’t go out and make that money to enjoy it with the ones you love, or for whatever purpose you have in mind.”
