well being to thin as you grow older has been linked to osteoporosis , so have a bit of meat not to much or you will get diabetes; but slightly overweight people have more dense bones to support themselves generally speaking but it has been documented....this is assuming this overweight person is not completely sedentary....umm of course ostocal or some produsct like that is also said to improve skeletal health

People gain weight for different reasons.  Some may simply be lazy and not care about their health or physical appearance.  Others may be depressed and use food as a comfort zone.  Others again may intentionally put on weight to make themselves unattractive to others so they are not hurt by a relationship going wrong(usually as a response to being hurt in the past)\n\nIt really depends on what their priorities and motivations are.  If they don't make their health and appearance a primary priority ultimately it will suffer.  Also note that it's one thing to be thin, it's entirely another to be healthy and fit.  You shouldn't link the two of them together.\n\nEdit/Addition: Actually numerous people here have answered your question.  It's not easy to just flick a switch in your head and reverse or change the things that are causing you to overeat or not exercise.  If it is a deeply traumatic issue that you have trouble dealing with usually it takes a LOT of work and a lot of motivation to break out of it.  The answer to your question is threefold:\n\n1. Some people are too emotionally depressed to make a change for the better and hence continue along the same self-destructive path OR\n2. They're medically ill and cannot help it (quite a rare case compared to the other 2 OR\n3.  They're too lazy\n\nHope that clears it up

Maybe it's inborn that you're skinny. You could try eating lots. And don't do any exercise.

Many overweight people are asthmatic.  It also often resolves itself upon weight loss.

could be a thyroid condition, could be medications or other drugs you may be taking. could depend on what your diet is. You may need to get blood drawn to test for possibilities on the reason behind the weight gain. and check side eefects of medication, if you are taking some

Yes. You can grow taller, and not gain weight as you do, which will make you look thinner as your original weight redistributes in your body.\n\nYou can also get sick in some way and start losing weight without knowing you are sick. (Diabetes or something.)

People have different frame sizes and would look absurd being a size 0 or 2...My weight has fluctuated all my life ...my lowest weight was like 145 and people told me I looked sick..as in way too skinny. Yes there are diseases and genetics also factor into metabolism and stress can for some people pack on the pounds. I had a recent weight loss and I was doing real good getting it off I had lost 60+ pounds in a course of 5 or 6 months but about 1 year later starting right after my mom died, I started gaining weight and no matter how much I tried to stick to the plan (diabetic food exchange) I still gained weight back I have gained about 40 pounds and in a course of 4 months and my eating has not changed that much to explain the gain, they say that stress make blood sugar go crazy (now I believe it). I am choosing the more excellent way in not mouthing off my opinion of your opinion, because after all you are entitled, just hopefully people don't use the same magnifying glass you use when you look at others when they look at you.

Metabolism......all young people are blessed with it, as you grow older it slows down. If you want to gain weight you have to eat more protine and things like that, its not always the sugar that makes you fat.

Yes, it suppresses your appetite, which should make you skinnier. But it also kills you and the people around you.

see a nutritionist. while eating a lot may help you a bit, it is also not healthy (junk food binge=tummy ache), especially if you are naturally skinny-you might end up just getting sick. it's also in the genes, so check if your relatives are skinny. if they are, chances are, you always will be on the slim side. oh, by the way, i know that there are exercises that can help you gain weight. ask your nutritionist about this too. =) good luck, and MAN DO I WISH I HAD YOUR PROBLEM! hehehe.

I think sometimes it can be difficult for people who carry some more weight than you to understand why you are thinner. There seems to be a lot of tasty food around now so mabye some just don't understand this. I suppose it comes down to a kind of jealousy thing.

Dear Fatty and Skinny,\n\nLet's start with metabolic rate. A person's basal metabolism represents the minimum energy expended to keep a resting, awake, body alive. The energy used in basal metabolism depends primarily on lean body mass. Other factors that influence your basal metabolism include: the amount of body surface (the greater the area, the greater the heat loss); gender (males average higher energy rates because of greater lean body mass); body temperature; thyroid hormone levels (higher levels increase metabolic rate); aspects of nervous system activity; age (metabolic rate falls as we age); nutritional state (eating less slows metabolic rate); pregnancy (metabolic rate increases); caffeine and tobacco use (metabolic rate increases).\n\nAbout being underweight, sometimes being too thin requires medical intervention. A physician can rule out hormonal imbalances, depression, and other hidden diseases such as anorexia or bulimia. Risks associated with being too skinny include complications in surgery and slow recovery after illnesses.\n\nYou seem to be on the right track in terms of what you can do yourself to gain weight. The reason people suggest weight lifting is because it has a tendency to add muscle mass--pure weight, more so than other sports activities, which add some muscle at the same time as one is also burning off many calories. As far as food choices, try gradually increasing your consumption of energy-dense foods, especially those higher in vegetable fats. Italian cheeses, nuts, and granola are good kcalorie sources with low saturated fat content (read the label to make sure the product is high in mostly unsaturated fat). Dried fruit and bananas provide other high kcalorie fruit choices. If eaten at the end of a meal, they don't cause early satiety. Try replacing foods such as diet sodas with good energy sources, such as fruit juice.

because anorexia and bullemia are serious eating disorders, it's a mental problem that they have and also known as diseases. If things are going bad in their life and they dont like their weight and obsess over it, they feel as if food is one of the things they are able to control in their lives. Just like alcoholism - it's hard for them to stop even if they want to.

Bets,\n\nA part of the reason why you gained weight is because your metabolism slowed down.  This is typical of college students (going from teens to 20s).\n\nJust bump up your cardio to burn off what you drink.\nLift weights to make your body denser.
