As mentioned in the other posts, you may have some problems which require medical attention. If you do, you should definitely see a doctor.
Telling a skinny person to eat more food in order to gain weight rarely works. The person who wants to gain weight is usually eating as much as he or she can. BTW many slender or even skinny people say that they eat a lot of food but they really dont (no offense). It is, however, a lot of food for them.
If, after seeking medical help, you are still unable to gain weight, its time to look at other options.
There are various high protein/caloric drinks that a person can take. You can make your own, or buy the powder or liquid. If you do try this route, you need to take the drink in addition to your regular meals. When I say regular meals, Im talking about three meals per day. Coffee and cigarettes do not count as a meal.
- Vitamin/Mineral Supplements:
In addition to the drink, you should probably take some sort of vitamin/mineral supplement. Ive read that minerals (especially calcium) can have a relaxing effect and can even help with sleep problems.
- The Wrong Way to Workout for Getting Big:
·When the high-metabolism person starts working out, they typically do things that actually hinder their gaining weight. I used to work with a guy who said that he wanted to gain weight. I asked him if he did any exercises. He said that his workouts consisted of running on the treadmill and doing curls. And he wondered why he could not gain weight.
·The typical high-metabolism approach to lifting would be to workout seven days a week for at a couple hours each day. Hed do stuff like curls, tricep extensions and running. He would go home exhausted but with the feeling that he really had a good workout.
- The Right Way to Workout for Getting Big:
·I recommend that you start lifting weights. Although you want to gain weight, I suspect that you prefer to gain muscular bodyweight. If your goal is to gain weight, you need to work the big muscle groups. When you look at athletes (and especially lifters) who have the most muscle, youll see that power lifters usually come out on top. This is because the exercises that they specialize on - bench press, squat and dead lift -- hit the big muscle groups.
·If you dont know how to do these exercises, there are all kinds of books and websites on lifting. Be sure to use good form.
·Keep your workouts short 30 minutes (or less) to an hour (at the max). When you first start, it should be no more than 30 minutes. Workout 3 days per week with at least a days rest between each workout. Your workout should go something like this:
Monday, Friday: Bench Press work up to a couple sets of 10 reps
Squat -- work up to a couple sets of 10 reps
Wednesday: Dead Lift work up to a couple sets of 10 reps (If you have problems with the bar slipping, you should probably drop down to a couple sets of 5.)
·During your workouts, Be sure to do lighter weight before you handle the heavier weights.
·Try to get a workout partner.
·Try to add weight each workout. A good goal would be increase of 10 lbs each week on the squats and dead lifts and 5 to 10 lbs each week on the bench presses. BTW -- if all this is new, you will probably have sore muscles for the first few workouts.
·However, because you are so skinny, even this might be too much. If it is, I suggest that for the first month or so, that you limit yourself to just one exercise the dead lift (still only once per week).
·There are several good basic workouts for gaining weight. Most, if not all, use either the squat or the dead lift as the key exercise.
