Does genetic morbid obesity exist? _With the acceptance of being a little overweight_ I hear of people saying they were born morbidly obese and it was genetically passed on. I'm aware being so obese leads to countless health issues, yet we have people defending fat shaming and the likes. Is the excuse of having 'obese' genetics scientifically justified? Do people have genetics that make them ridiculously fat? Alongside, would this simply be down to the diet of the person from a young age? Thanks.

It's a myth that obesity is mostly caused by genes. Yes, there are many genes that predetermine your apetite but when a baby is born obese, it's not a matter of genes but a matter of the mother's health and diet. And because till the birth, the fetus shares a single bloodflow with the mother, it gets everything the mother has in her blood. Thus, some babies are born obese, some are born addict.

Indeed, there are papers showing that there's a higher chance for the newborn to die during birth, even though you can't always say what was the main cause of death (also it depends on what you connect with obesity).
