Who Knows Best

Two of the country's weight loss experts, personal trainer Paul Connolly and alternative therapist Janet Thomson, go head to head to prove that they know the best way to tackle obesity.

For personal trainer Paul, who has trained Hollywood stars like Demi Moore and Elle Macpherson, physical exercise and hard graft is the only way to lose weight. He says 'People are fat because they're lazy.'

With more than 20 years experience in clinical hypnotherapy, Janet's approach is to focus more on the mind than the body. She says: 'Everything someone puts in their mouths is motivated by what goes on in their head. If you can get inside their head... you can change their body - forever.'

Paul and Janet both select a member of the public for each other, someone who is overweight or obese. They then work on their new client, agreeing that the best method will be the one that gets their client to lose the most pounds in six weeks.

Paul helps 28-year-old Emma Johal, who is a married mum of one. At 21 stone 2, Emma is obese.

As well as a poor diet, Emma does no exercise. She's struggled with her weight since childhood but a recent health scare has given her a wake-up call. Paul's first steps are to get Emma exercising for the first time in her life as part of his strict physical regime before he moves on to boot camp in an attempt to get Emma to shed some pounds.

Alternative therapist Janet Thomson believes the secret to weight loss lies in changing how you think but how effective will this approach be on 21-stone Sharrema, who's never been happy with her weight but has struggled to stop comfort eating all her life?
