Breastfeeding may help mums stay slim
London: Breastfeeding may help women keep their weight in check and make them less likely to become obese, as they get older, a new study has revealed.
The scientists discovered that women who breastfed their babies even for a few months after the birth were less likely to be obese 30 years later.
The Oxford University researchers concluded that for every six months a woman gives her baby breast milk, she loses around 2lb – depending on her initial weight and height.
Although this is not much, the academics claim that it could help prevent thousands of deaths from cancer, heart problems and other illnesses related to obesity.
Doctors have been concerned that many women are becoming obese by gaining weight during pregnancy, which they never manage to shift after the birth.
If such women go on to have several children, they will become progressively fatter with every pregnancy.
The latest study – involving more than 740,000 women – provides compelling evidence that breastfeeding could help reverse this weight gain, and then help women fight the flab for good.
Breastfeeding leads to burning of large amounts of energy and experts have previously calculated that it burns 500 calories a day – equivalent to a typical gym session.
Now academics have worked out that for every six months a woman breastfeeds her baby, her body mass index – the measurement of obesity – falls by 1 per cent. An average woman who is 5ft 6ins tall and weighs 11st 1lb would have a BMI measurement of 25, which is classified as overweight.
But if her BMI was to fall by 1 per cent it would be about 24.75 – which is deemed ‘healthy’ – and she would weigh 10st 13lb.
“We already know breastfeeding is best for babies, and this study adds to a growing body of evidence that the benefits extend to the mother as well – even 30 years after she’s given birth,” the Daily Mail quoted lead author of the paper, Dr Kirsty Bobrow, from Oxford University, as saying.
“Pregnant women should be made aware of these benefits to help them make an informed choice about infant feeding,” Bobrow said.
Professor Dame Valerie Beral, director of the Cancer Epidemiology Unit at Oxford University, who was also involved in the study, said that the research showed that the minimal reduction in BMI would lead to fewer deaths from obesity related ailments.
“Our research suggests that just six months of breastfeeding by UK women could reduce their risk of obesity in later life,” Beral said.
“A 1 per cent reduction in BMI may seem small, but spread across the population of the UK that could mean about 10,000 fewer premature deaths per decade from obesity-related conditions, such as diabetes, heart disease and some cancers,” Beral said.
The study surveyed 740,600 women whose average age was 57. They had all answered questions about how many children they had and the total number of months they had spent breastfeeding.
The research also found that women were more likely to be obese if they had several children.
This backs up the concerns of health professionals that many gain weight during pregnancy, which they don’t lose after the birth of their babies.
The World Health Organisation (WHO) recommends that women breastfeed their babies for at least six months but many give up because they find it uncomfortable or are worried that their babies are struggling to get enough milk.
The study was recently published in the International Journal of Obesity.
