A new study reveals that siblings may have something to do with your weight gain!

A report published in the Journal of Epidemiology & Community Health reveals that first-born sisters often put on more weight than younger ones.

The research – which studied 13,000 pairs of sisters over 20 years – found that older sisters are 40% more likely to be obese and 29% more likely to be overweight than their younger sisters.

They also had higher BMIs when they were pregnant, and have a higher risk of diseases such as diabetes and high blood pressure.

The study – which was conducted by researchers from Sweden and New Zealand – doesn’t elaborate on exactly why this happens.

Research has previously been conducted on first and second-born males which produced similar findings.

Professor Wayne Cutfield from the University of Auckland believes that the blood supply to the placenta during a woman’s first pregnancy is less, and that a lack of nutrients as a result could lead to a greater risk of fat storage and less effective insulin regulation later in life.

Not convinced tbh! I am the youngest and my sister is much smaller than me.

Is this true for your family?

  • If his theory was correct wouldn’t this also be true for brothers and mixed gendered families. I think they need to do more research to work out what’s going on.

  • Not the study… but my siblings constantly telling me I was fat didn’t help. It made me think I was, even though I now look at photos and realise that I wasn’t.

  • Well this is an interesting study. I don’t think I’m convinced and it wouldn’t hold true for my family.

  • My older sister is about 20kg lighter than me. But I’m a taller and a bigger frame than her – she’s tiny.

  • I’m the oldest and even though I’m not fat, my sisters got blessed with having the perfect bod!

  • I’m the middle child and also the biggest.

  • I am the middle child. My older sister is a little bigger than me and my youngest one smaller. But it could just be a coincidence.
