How can I gain weight quickly?

Well, gaining weight you can do a lot faster than losing it. I'm assuming you want to lose weight. Your best bet is to eat healthy- fruits, vegetables, and lean meats (chicken, for example. No red meat!!). Start working out doing a mix of cardio and strength training. Cardio is good for burning calories, but strength training builds muscles which leads to a faster metabolism- muscles burn calories even while you sleep, so building up muscle (not really bulky weight lifter type, but toning up) will mean you will burns a few more calories throughout the day, even while you rest.

First of all, did you intend to ask for weight loss advice or weigh gain advice? There are many websites out there that can help you to learn how to count calories, which is a foolproof method of gaining or losing weight.

You want to gain weight or lose weight? There is a big difference between them. For medical advice consult your doctor!
