Researchers found more than half of women admit to banging on about calories, sugar content and health risks around certain foods to anyone who will listen while they are watching what they eat.
Almost one in four even admitted to ‘preaching’ to their friends about the consequences or benefits of consuming different food and drinks or why they should go on diet.
Worryingly, 41 per cent of women claimed they have stopped eating something after their ‘food bore’ friends’ scared them into changing their diet.
A spokesman for The Simply Great Drinks Company, which commissioned the research, said: ‘This study shows we are turning into a nation obsessed with dieting and talking about diets.
‘Of course we all want to look and feel our best, but we can achieve this without adopting unsustainable regimes and turning into complete food bores.
‘We are firm believers in an ‘everything in moderation’ approach to a healthy lifestyle and we have just launched an eight week challenge aimed at supporting people as they make manageable and lasting changes to their existing diet, exercise routines and mind set.’
The Be Simply Great campaign is fronted by Olympian Victoria Pendleton and backed by a panel of experts: Dr Christian Jessen; Charlene Hutsebaut, personal trainer; Jo Hemmings, media psychologist and Charlotte Stirling-Reed, nutritionist.
Dr Jessen added: ‘In general, diets require a lot of sacrifice and often involve a huge lifestyle change.
‘So it’s only natural that it becomes a big topic of conversation for you.
‘However, I say ditch the diets and opt for sustainable change instead – it’s better for you long-term and your new lifestyle won’t take over your life and your conversations.’
The study of 2,000 women revealed that eight in ten spend more time than usual talking about food while they on a diet, with 56 per cent going as far as saying they become complete ‘food bores’.
Six in ten say a diet completely takes over their life when they do on one, with almost three quarters saying they have to focus all their thoughts and efforts on their food in order to stick with their diet.
More than one in five also said their friends have accused them of becoming obsessed about food while they are on a diet.
What they’ve cooked recently is the most popular food-related topic of conversation for women on a diet, followed by what they have had to eat or drink that day and the calorie count.
The right food and drinks to consume, alcohol consumption and sugar or fat content also dominate the conversations of women on a diet.
But the constant chat about food can have a huge effect on friendships with 27 per cent admitting to nagging their friends to join in whenever they go on a diet.
And 38 per cent go on at their friends about the various health risks and benefits from consuming certain food and drinks.
One in four even said they are aware of occasions where they have left their pals feeling guilty about their diet after going on so much about what they should be having.
It also emerged that 35 per cent of women avoid certain friends who are on a diet because they know they will end up making them feel guilty about what they eat.
Another 45 per cent don’t eat particular foods in front of some of their friends because you know they will go on about how bad it is for them.
