As I mentioned in an earlier post, there is a Horizon special, “What’s the Right Diet for You” going out this week on BBC2; click on the above link and it takes you to the Horizon home page where you can watch the programme and do an online test to see what sort of dieter you are. Sadly this is only available to people based in the UK, but I think that even if you are not based here you can still see the added content.
For those who haven’t seen the programme, in the film a team of scientists from Oxford and Cambridge use a range of tests to divide 75 overweight volunteers into 3 “tribes”.
The tribes:
The Constant Cravers: those who have genes (such as the FTO gene) which put them at greater risk of becoming obese
The Feasters: people whose bodies produce low amounts of a gut hormone called GLP-1 in response to food. GLP-1 tells the brain “you have eaten enough”. Feasters go on eating because their gut takes that much longer to say to the brain, “you’re full”. In the Horizon film they are the ones who eat the most at a buffet.
The third group are the Emotional Eaters. They were selected on the basis of responses to a psychological questionnaire and are typically the sort of people who turn to food when stressed.
The diets:
Each tribe is then given a different diet to try; Emotional Eaters get a standard low calorie diet with psychological support. Constant cravers are put on 5:2 intermittent fasting and “Feasters” go on a high protein, low GI diet. If you go to the website you can get lots more information and helpful recipes.
I was pleased that Professor Susan Jebb, one of the UK’s foremost diet experts, had chosen 5:2 intermittent fasting as a solution for the Constant Cravers. They are probably the toughest group to help since their genetics make them particularly susceptible to over-eating.
My reaction:
I think it is a novel way of approaching dieting and the dieters do impressively well on their allocated programmes. The reality, of course, is that most of us are a mixture of the three tribes (I am mainly Constant Craver, with some Feaster and Emotional Eater thrown in). I also think that most of us would benefit from all 3 solutions.
A diet high in protein and in low glycaemic carbohydrates, the advice given to the “Feasters” will keep you fuller for longer, whatever your tribe. And I, naturally enough, think most people would benefit from doing the Fast Diet, whether they are Constant Cravers or not.
As for the Emotional Eaters, well most of us would relate to that. Losing weight is tough and we need all the psychological support we can get, whether it is family, colleagues, or people they meet on a site like this one. One of the purposes of this website is to bring people together to help each other and I have been delighted by the atmosphere and the helpful comments made by many people.
Best, Michael
