Medical Forum / General / General / July 2007Obesity - genes or habits?
In America, are more people fat because of their genes or because they overeat? I bet it's mostly genes because most people don't want to be fat. Of course there are stupid slobs who don't care about anything but eating. They are often morons with oversized shorts too. Have you seen families where one sibling is much fatter than another?

If you consume more calories than your body burns, your body converts the excess calories to body fat, and you gain weight. If you consume less calories than your body burns, your body converts body fat back into the calories it needs to run, so you loose weight. Depending on your "genes", the amount of calories (kcal) your body needs every day is averages between 2000-3000 a day. For average women, the average is more like 2000, for the average man its probably more like 3000. You can also increase you activity, which will increase the amount of calores your body burns, which you should do if you want to loose weight (especially if you're a couch potato). > Have you seen families where one sibling is much fatter than another?

It say it is genetics or because they overeat is misleading. It takes both genetics and environment. The two go together. It is like asking whether a PB&J sandwich is more peanut butter or jelly. > I bet it's mostly genes because most people don't want to be fat.

Just blame the victim? > Have you seen families where one sibling is much fatter than another? yeah.

I have always had to exercise a lot and consume less food than my friends to stay in "sort of" good shape. Never could get a perfect body, but didn't allow myself to be fat like everyone in my family. But whenever I got sick and couldn't exercise for several days, I gained a few pounds easily. I had to start right back on the exercising after I was no longer sick. {I exercise literally several hours a day, and the rest of the day I'm constantly thinking of sneaky ways to get more exercise} But I do know a lot of people who had to do a lot of eating, and couch potatoing to get a sliver of weight. One of my best friends also has tried everything from overeating, to weight gain supplements to gain weight (and he's not that active either). And when he gets sick for a couple days and can't keep up the weightgaining regiment, he loses pounds fast and gets down on himself. Then when he's not longer sick, he has to work at it again to gain that weight back. [Note, I'm using sick as an example, but this also applies when my friend or I are just too busy with other things for a couple days]. I remember overhearing, on more than one occasion, skinny people in gyms complaining to their friends about losing several pounds because they couldn't keep up their weight gaining regiment for several days. This always suprised me, because it was always the opposite for me. So.... genetics does play "a part." Anyone that gives you a simple "calories in, calories burned" explanation is missing 95% of the story, which is the middle part of the equation (what is your metabolic rate? does it shift your metabolic rate lower when you eat less and exercise more? when you miss a few days of training, does your body "maintain" itself or use this as an excuse to quickly "revert"? does it have a tendency to "float" to a certain natural weight? does your body tend to convert extra calories into muscle or fat? does your body automatically slow it's metabolic rate down when you eat less? are you getting proper sleep (sleep disorders can cause weight gain)? etc. etc.).

America just has more per capita. So, unless those from India or China are drawing from the same gene pool....

That's a stupid statement. You're making a wildly ignorant assumption that DNA is the same as genetics. We all have the same genes. It's a matter of which are turned on, off or activated by a matching gene from a parents, etc. Crack a book once in a while.

Not at all. The statement about "same gene pool" refers to alleles (forms) of the genes. A well-known example might be normal and sickle hemoglobin, two alleles of the hemoglobin-beta gene. Yes, we all have a hemoglobin beta gene, but some have one form and some have another form. The distribution (frequency) of those two alleles may vary from one population to another. In fact, in this case, they do vary, reflected in sickle cell disease being more common in certain groups. has nothing to do with gene regulation. There are presumably genes for which different alleles have different effects on obesity. People with one allele might then be more prone to obesity. The frequency of such an allele might (or might not) vary between populations. This is what is meant by referring to the gene pool. My only quibble with the gene pool point is that I don't know why we would assume a priori that the gene pool re obesity would differ for different populations. bob >You're making a wildly ignorant assumption >that DNA is the same as genetics.

"My only quibble with the gene pool point is that I don't know why we would assume a priori that the gene pool re obesity would differ for different populations." On the flip side of that coin there is also no reason to assume that the obesity gene would be the same in differing populations, (if there even is an obesity gene!) To assume that genes are the major contributing factor to obesity is to over look the facts that more food is available to all three populations and less work is required to get this food. You can take almost any animal, put it in a sedentary environment with an abundance of food and that animal will almost invariably become fat. Wether that is genetics influenced or not.....The whole is greater than the sum of the parts.... To assume otherwise would be (as a previous poster stated) " a stupid statement.

A mongolian persons DNA is not the same as an Africans. Mongolians do not have the allele for sicklecell anemia while Africans usually do. It is believed that the sicklecell "mutation" was in response to malaria. Try thinking before you speak.

Try thinking before you > speak. You're really, really confused about the difference between DNA and genes. The DNA, which is more than just the genes, as you even noted by pointing out Mongolian DNA is different from African DNA, is responsible for telling the genes what to do. Like the skin color gene is flipped on, off, black, white, by the DNA. I did think. You obviously prefer no tto and keep digging a hole.

Your genes are composed of DNA. Hence if the DNA is different between a Mongolian and an African(which you agreed was) then the genes are different. No. You cannot "flip on" the sickle gene in a Mongolian unless they have African DNA in thier system that allows for the sickle cell mutation. That's what a mutation is. Human's do not have all the same genes. Read any simple books on human genetics and you will see that. If you don't understand genetics then maybe you should stick to the celebrity gossip forums. I'll give you the last word, because I'm not going to argue a point that is above your head.

You're spinning your argument away from your original moronic statement because you probably did finally look it up. But thinking people already saw you make a fool of yourself. And if you didn't want to opinion of people who spend their recreational time in a gossip group, which has nothing to do with the level of their knowledge, perhaps you should snip out those groups when you post. It's probably pretty embarrassing for you when people who think the same limited way you do see the gossip fluff denizens run rings around your pea-brain.

You can have the genetics to be obese, but you still have to eat the food and sit on your butt in order to make it happen.
