Is anyone overweight genetic?

my bioligist teacher say the people who are overweight its not because of their inheritance or because there are populace in their family connections that are overweight. He says it have nothing to do near genetics and that it is not inherent. I am talking to one the nurses at my assignment and she says that he is wrong. cand someone please clarify . thankfulness !
Answers:
Some people may own genes that enable them to munch through less or more earlier they become overweight. But in nonspecific, it is the lifestyle one follows that determines whether he/she will be overweight (diet, exercise).

For example look at the USA. We are the fattest country in the world. Our ancestors come from Europe, Africa, Asia, and many other areas. Yet, they are not overweight. Why? Too copious of us lead a sedentary lifestyle, combined next to fattening foods.
Yes and no. There are genes that increase someone's tendency to be overweight, but overall it is NOT genetic. Weight comes when you lift in more calories than you use, so you increase your reserves (fat). Simply by ingestion less and exercising more we would not own an obesity problem.
It is down in the mouth that there are so several people trying to variety this claim, it just give people an excuse to be overweight and not engineer the effort to stay strong.
Yes and studies show that its also contagious.
I think it's an uver-used excuse, but I assume there're some validaty

But the cold easier said than done fact comes through within yes, weight is purly determined on how much you munch through compared to how much you burn. There is no way to get through and burn the excat same amount of calories, and still gain weight. That defys the first rule of thermodynamics (don't infer of it in lingo of thermodynamics, just physics) you can't bring something for nothing.
Some associates may be genetically predispositioned to becoming overweight, but it is still very much an environmental condition. It doesn't business whether your genes make you more prone to put on consignment or not, if you don't overeat and engage contained by regular physical exercise then you aren't going to grasp fat (barring singular and extreme genetic conditions such as MOMO syndrome).
It's complicated. Look up "leptin" on your search engine.

I'm sure your biology coach has discussed quality versus nurture. While an obese family may share the leptin gene, they also may share indistinguishable sedentary life-style and poor eating conduct.

I would say that within most cases we eat too much and exercise too little. Genes may play a role near some people. Tell your guru it's "multi-factorial." He can't give you smaller number than a C for that.
