This is a study which affects all animals and humans. It is a study which concerns mice who were given a poor diet extremely high in fat and sugar. It was found that this poor diet had an effect upon the metabolism of great granddaughters who developed insulin resistance and suffered other metabolic problems despite the fact that they were fed a healthy diet. The likely cause, it is thought, is a change in the mitochondrial DNA of the mice which is then passed down the maternal line and affects how cells produce energy.
This is an interesting study. It concerns obesity. We know that there is an obesity epidemic in domestic cats and in people in the West.
What the study is saying, as I read it, is that you can inherit obesity problems from your great grandparents!
Concerning cats, it is fortuitous that most random bred cats are spayed and neutered. Some purebred cats aren’t because they are breeding cats. However, if an obese cat is allowed to reproduce then it would seem that this study would apply to her/him in that her offspring and subsequent offspring may suffer metabolic problems associated with obesity and a poor diet notwithstanding that their diet is excellent.
I think people should at least pay heed to this study. It suggests that obesity can become fixed in the maternal line which is worrying because it presents another barrier to eliminating obesity.
