    Celeb trainer: Diet is key to weight loss

    CELEBRITY trainer Bob Harper of TV show The Biggest Loser has built a career by putting obese people through some gruelling fitness regimes.

    But, if he's learnt anything from the experience, it's that diet trumps exercise every time.

    "It is all about your diet," the 48-year-old said during a break from filming Season 15 of the long-running show.

    "A long time ago, I used to think that you can beat everything you eat out of you, and it's just not the case."

    Harper has turned working with people who are overweight by 45kg or more into an empire, with DVD workouts and a best-selling book, The Skinny Rules.

    In addition to promoting a healthy diet, a big part of his exercise routine includes lunges and other core-strengthening moves.

    He has also taken to Crossfit, a series of timed, ever-changing physical challenges.

    "I'm working with people who are 227kg and doing Crossfit on a regular basis," said Harper, who described the workout as well-balanced.

    "To me, Crossfit makes complete sense, (as long as) you work at your level, doing the things you can do with proper coaching," he said.

    Dr Mark Kelly, an exercise physiologist at the American Council on Exercise, cautioned that "Crossfit has very ballistic training".

    "You're asking people to move fast through a large range of motion. Even with coaching, the foundation of stability, mobility and psychomotor skill has to be laid (first)," he said.

    Dr Kelly agreed that diet is the main factor that can lower weight, but it's exercise, he added, that keeps the weight off.
