Why are some people fat ?

Hi am just wondering I mean I eat unhealthy food and I don't work (I only started a week or soo)
But I never gain weight so how come some people are fat ?

They arent lucky enough to have your metabolism?

um...well sum people have a fast matasilizum and sum people have a slow 1...sooo thats prob. why you dont gain weight and stuf..but people are fat because they eat a lot and sont exercise enough...

your metabolism is fast thats why. Like men metabolism is faster than womens thats why they can lose weight easier and faster.

oh that make sense
btw I don't eat a lot but almost every thing I like to eat is unhealthy

It could be a lot of things, Like Metabolism, genes, what they eat. I got a question why are some people stuck up snobs? Sorry could'nt resist LOL.

I am fat, but I don't eat a lot. I excercise everyday for at least an hour. It isn't always related to food. Like wutangfan said, it can be all sorts of things. That's why it's hard for me to lose weight.

My sister is very very overweight... but that is because she is sick. She was rapped when she was only 9 and it continued until she was 15.. she had a few surgeries also and she is 21 now and still not losing weight. The person ruined her life... they did that... sometimes its not the people who are over weight faults... it is sickness also...

Everybody is different. we all have different bodies. we all have different metabolisms. others burn more than others. also a part is heredity.

There was actually some programme on tele not so long ago, a little experiment they did. Basically they made people who have a fast metabolism and never put on weight, eat a lot, and surprise surprise, they started to put on weight. So whilst I reckon metabolism plays a part, it's also a case of how many calories you eat (how much you eat). You can eat unhealthy crap and still not put on weight, similarly you can eat healthy foods and put on weight if you eat too much!

cause eat to much

Loosing weight is difficult because when we eat fewer calories than we burn our body gets more efficient with every bite we eat to avoid loosing weight. Our bodies don't know we are trying to loose weight, most of human history our food supply was not dependable so we had to survive famines. When we eat less our body goes into starvation mode to make our fat last as long as possible since there was no telling how long a real famine would last.

Our bodies also produce a gnawing hunger when we eat less than we burn. Many people can muster the willpower to resist this hunger for days, weeks, months, or even years but usually it wins out and we gain back the weight we lost. Only about 5% of dieters keep the weight they lost off long term. That is one in 20. Pretty long odds.

Some people today are lucky not to gain weight as quickly as other people. The genes that help them remain slim would make them less likely to survive a food shortage in other times. Fat people are more famine resistant.

its not always because of eating to much. I was always a chubby baby and I say im fat now and stuff. I dont eat so much and I exercise a lot.I have a low metabolism so that makes me gain weight easier than other people, well I guess thats how it works. im not sure

well according to some people everyone`s body is different but some people just eat wayy to much lol
