TVB has recently finished showing the first series of Channel Four’s "You are What you eat". The concept behind the show is that "leading nutritionist" Gillian McKeith advises an individual or family on adopting a healthier diet and lifestyle. It’s all good knockabout stuff – fat people meet a stern Barbara Woodhouse type who bullies them into giving up their chip butties and eating spinach and mung beans instead, and they lose weight.
The shows I have seen all seem to follow the same pattern. "Dr" McKeith (she’s not a real doctor and her PhD was acquired through a correspondence course) visits her victims, rifles through their kitchen cupboards and berates them for eating deep-fried Mars bars, burgers and chips, and washing it down with litres of fizzy drinks. They are horrified to discover what they are eating (having presumably not noticed what was in their shopping baskets) and are then presented with a table laden with the healthy food that they are to eat for the next eight weeks. Some looks OK, some doesn’t. After a few weeks they have a confrontation with "Dr" McKeith because they don’t like the food (or in one case because "avocados are too dear"). She puts them right, and they carry on with the diet.
After eight weeks they have lost two stone (it’s always two stone). They’re healthier and happier and have loads more energy.
In truth, how could they go wrong? Replacing junk food and fizzy drinks with fresh fruit and vegetables is bound to bring about an improvement, especially for someone who is seriously overweight. Adopting a healthier diet for a couple of months (especially with the incentive of being on the telly) is not that much of a challenge.
