How do you gain weight?

peanut butter helps put on muscle weight. Don't look for fat, just get more muscle weight and it will look much better. Also try to work out with kattle bell, it helps develop almost all muscles, even those you never thought you had. must say that after working out for just a few minutes with it i discovered many muscles, and all of them were soar. it's much better then working out only a few muscle groups.

I also had the same problem, I even tried the chinese red pill called (Ling Zhi), it increases your appetite and you eat like 5 times a day even more. However, some says it has steroid which is harmful to health if you intake too much. I think the only best way to gain weight is to wait until your body particularly metabolism slows down cause usually when you get older the metabolism starts to slow down a bit which eventually leads to gaining weight faster. But of course we don't want to wait till we get old just to gain weight, we would miss a lot esp our youthfulness..LOL.

Yeah if you want to put weight then you need to ear lot of junk and fastfood daily basis

i think the high prevalence of obesity and overweight problems in our culture means much more emphasis is placed on losing weight rather than gaining weight. It is easy to forget about people who have the problem of being too thin.
Being underweight can result from eating disorders, chronic diseases, and it is also a concern for athletes and naturally thin people who wish to be bigger, stronger, and more muscular. Elderly people may become underweight. The gradual loss of taste and smell, or the inability to prepare healthy meals, results in becoming too thin.

While being overweight or obese is a well-known risk factor for chronic diseases, being too thin may also increase a person's risk of dying from diseases such as heart failure and cancer. Elderly women who are underweight may become frail, which means they are more likely to suffer from osteoporosis and hip fractures. Being underweight may also increase a man's chance of erectile dysfunction.

What To Eat To Gain Weight
Increasing your intake of junk foods and greasy foods is not a good way to gain weight. Junk foods usually contain unhealthy trans fats or saturated fats. Even though you need to increase your calorie consumption to gain weight, those calories should come from foods that are good for you.
Healthy fats include omega-3 essential fatty acids sources like tuna, salmon, flax, and walnuts. Good sources of protein include lean meats, fish, poultry, nuts, seeds and legumes. Healthy carbohydrate sources include fruits, vegetables and whole grains.

It may be easier to eat five or six smaller balanced meals per day rather than eating three large meals, especially if you are not used to eating much at one sitting.

Protein powders and nutritional supplement drinks such as Ensure (buy direct) can be added as in-between meal snacks if you still need more calories. Some protein powders are flavored and only need added water and some others can be blended with your choice of juice or milk to improve the taste.

It would also be a healthy idea to add a small amount of flax seed oil and some psyllium powder to add some omega-3 essential fatty acids and extra fiber.

Dietary Supplements and Gaining Weight
A high-quality multivitamin and mineral supplement is a good idea to make sure you are getting all of the vitamins and minerals you need. Some people find that their muscle mass increases with protein supplements that contain certain blends of amino acids such as creatine (buy direct) and glutamine (buy direct). Some people who are very ill may need liquid nutritional preparations that are available through their doctors.
Resistive Exercise To Gain Weight
Exercise is also important for healthy weight gain. Resistance training exercises such as lifting weights will help to increase your muscle size. Aerobic exercises such as running and stationary bicycling are better for fat loss and excessive aerobic training may cause you to lose more weight. Resistance training can be done at a health club, gym or at home with the proper equipment.
Remember that it can take a while to gain the weight you need, but be patient and continue to choose healthy foods until you reach your goal weight.

Tools to Help You Gain Weight
Use these tips and tools to help gain weight:
Start with this Calorie and Nutrition Guide to find out how many calories you will need to reach the weight you desire.
Use a food diary to track your calorie intake to be sure you are getting all of the calories and foods that you need.
You can also use an online program such as Calorie Count Plus to track your calorie intake, your exercise and your changes in weight. Calorie Count Plus has a large data base of nutrition information for almost any food you like to eat.
Add healthy calories to breakfast with an extra slice of whole-grain toast and peanut butter.
Mid-morning and afternoon snacks should be nutritious, not junk. Trail mixes contain healthy nuts, dried fruits and can add healthy calories to your diet.
Don't add calories to your meals by choosing unhealthy fried foods such as french fries, chicken nuggets and fish sticks. Choose healthy foods such as baked potatoes, baked chicken and fish, just make your portions a bit bigger.
Keep your meals balanced. One meal should have a healthy protein source such as fish, low fat meat, chicken or legumes plus two or three servings of vegetables. Green vegetables add lots of vitamins and phytonutrients while starchy potatoes and corn add extra calories.
Drink healthy beverages such as milk and fruit juices to add calories. Don't choose sugary sodas, which only add calories and no nutrition.
