Are Genetics always true?

Say if two couple were over weight, like always ate unhealthy and didn't execise much, maybe having health conditions. If they had a baby, after it grows up, would the genes affect the kid. How about if the kid improves on healthier foods and exercise. I mean, I know you can't change genes, but can you improve them somehow. What if the kid suddenly becomes overweight because of their parent's genetics? I mean do genes affect you when you age older or something and is there a way you can improve them unlike example of the obese parents.

genes don't predispose you to anything but trigger in the environment... so you can have the gene for something, but it will only manifest if you also find the environmental trigger for it. As far as overweight people, for instance some people may have genes that make sugar more sensitive to their bodies and that causes more of an insulin response and more problems with weight.

I don't know of any gene that makes you fat. From what I've learnt in biology, someone becoming overweight depends mainly on environmental factors such as food consumption or how much they exercise. As for your question about genes and age, some genetic disorders only become prevalent when you reach an older age such as Huntington's disease. The only way I know of to change genes is through mutation, though in most circumstances, the mutation is harmful or unwanted; in some rare cases it can be beneficial.

Genes do play a part. How much, that's debatable. Why do you ask, i love lions?

If both parents are obese, but have diabetes, the child can be pre-exposed to it. This doesn't mean the child has it. It depends on the the child's diet etc. If the child isn't healthy he or she is most likey to have diebetes, as a child or in adulthood. Also if you have a weak immune system, you can get other auto-immune diseases, whether your parents are healthy or not. Obesity isn't included in this, as its not proven that it is heriditery, only the health issues that come with it can.

So I think genes do have a part, but not always.

Genetics are a part of it. You genes can increase the risk for you becoming overweight, but that doesn't mean that you have to be overweight. It just makes it a little bit harder to stay at a healthy weight.
