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?
