Survey says… most women still believe the 'eating for two' pregnancy myth

A survey of 2,100 women in the UK has shown that 4 out of 5 aren’t sure how many calories to eat when pregnant.

Many women still think that you should “eat for two” during pregnancy, according to the National Charity Partnership (NCP).

Busting the eating for two myth

The NCP survey showed that more than 1 in 3 pregnant women think they need to eat 300 or more extra calories every day. And 61 per cent think they need to start eating the extra calories in the first or second trimester.

Alex Davis, Head of Prevention, said:

"The “eating for two” myth has been around for years, but it’s very unhelpful. Eating healthily and consuming healthy portion sizes are important before, during and after pregnancy to increase the chances of conceiving naturally, reduce the risk of pregnancy and birth-related complications and stave off health problems like Type 2 diabetes and heart and circulatory disease in the long-term."

Current guidelines

First and second trimester

In the first six months mums-to-be don’t need any extra calories. Eating a normal balanced diet of no more than 2,000 calories per day during the first and second trimester is the best thing for mum and baby.

Third trimester

Pregnant women only need an extra 200 calories per day in the third trimester only.

The NCP also found that over a quarter of pregnant women used ‘eating for two’ as an excuse to eat unhealthy snacks or meals. In response, the NCP are working with the Royal College of Obstetricians and Gynaecologists (RCOG) to bust the myth and encourage healthier choices.

"Eating too much during pregnancy and putting on too much weight can be detrimental to both mother and baby. Women who are overweight during pregnancy are at an increased risk of having a miscarriage and developing conditions such as gestational diabetes, high blood pressure and pre-eclampsia."
Professor Janice Rymer, Vice President of Education for the RCOG

Our midwife Sophie's take on the survey:

"We know that it can feel like you are constantly ducking and diving between the foods to avoid and those that are great for you and your growing baby in pregnancy. But no matter what, it is important to know that you are doing a fabulous job!  We know that for most of us, eating yummy food is one of life’s greatest pleasures, and healthy eating can be tough, but hang in there! There are still plenty of tasty pregnancy-safe treats that you can enjoy whilst giving you and your growing bump all of the nutrients it needs to flourish!"
