How to quickly gain weight?

Hello,
I'm 22 years old and I weight 105lb. I am so unweight it's unbelievable. I need someone to recommend something to me so I can start taking to gain weight a.s.a.p. The thing about it is in the past when I would gain 5lb it would go in all the...

right places. But I feel weid come I'm not the right weight for my age and I feel like a child and not a woman. I need do need advice a.s.a.p. Don't tell me eat because I already do that. Tell me something you have used that really works. Thank you

weight gain shakes...you can find them everywhere pretty much, go have smoothies, thick creamy filled with sugar cream and yogurt...and have them add weight gain powder in there...I mean I used to have protein powder added in there...hmmm, what else, have fast food burgers, did you watch that movie Super size me about that guy who did a documentary on this, he gained like 40 lbs in 30 days or something, but also do eat healthy, don't b chowing down hamburgers 3 times a day like he did. get your thyroid function checked...hyperthyroidism creates a faster body metabolism, which doesn't help you gain weight, so you burn everything doesn't matter how much you eat...and your hormone levels...

good luck, hope this helps
