Women eat more unhealthy foods
and tend to put on weight when they move in with a male partner, according
to a new report by the University of Newcastle upon Tyne.
On the other hand, a man's diet tends to become healthier when he starts
cohabiting with a female partner - and her influence has a long-term
positive impact.
The reason for the change in dietary habits, say experts, is that both
partners try to please each other during the 'honeymoon period' at the
start of a cohabiting relationship, by adjusting their routine to suit
their partner and eating food that he or she likes.
However, women have the strongest long-term influence over the couple's
diet and lifestyle, mainly because the majority of female partners still
assume the traditional role of food shopper and cook.
The report, by Newcastle University's Human Nutrition Research Centre,
is published in the health professional title Complete Nutrition.
It reviews the findings of a variety of research projects from the UK,
North America and Australia which looked at the eating and lifestyle
habits of cohabiting heterosexual couples, including married couples.
The research shows that women are more likely to put on weight and increase
their consumption of foods high in fat and sugar when they move in with
their partner. Men, on the other hand, report a reduction in 'bad foods'
when they begin to cohabit, reducing fat and sugar and increasing consumption
of vegetables.
Women are also more likely than men to turn to food to deal with emotional
stress in their relationship. Women have been found to gain weight when
they quit their relationship, but the same finding has not been observed
in men.
Yet the report also highlights one study where both men and women were
found to put on weight after they started living together, which experts
suggest could be due to changes in eating patterns and a tendency to
make less time for exercise.
A key reason for the change in dietary habits is the symbolic nature
that food assumes in a relationship. Many cohabiting couples reported
food as being central to their partnership, and eating together in the
evening was an ideal sought by many.
The report's author, Dr Amelia Lake, a research fellow with Newcastle
University's Human Nutrition Research Centre and a registered dietitian,
said the research findings highlighted major health issues which couples
needed to address as a team early on in the relationship.
The research findings confirm work by Dr Lake which found more men than
women found their partner to be a positive influence on their diet, in
terms of encouraging them to eat more fruit and vegetables, eating regular
meals and taking control of their food shopping and preparation.
Dr Lake said:
“ You can't just blame an unhealthy lifestyle or
diet on your partner, as there are many other things that affect what
you eat and do. However, research has shown that your partner is a strong
influence on lifestyle and people who are trying to live healthier lives
should take this factor into consideration.
_ Couples who move into together should
use the opportunity of the honeymoon period to make positive changes
to their diet and lifestyle
by working together and supporting each other.
_ But couples who have been in their
relationships for longer should remember that it is never too late
to make changes and again this needs
team work.”
