Are there nutrition bars similar to the "caltein" bars used in Mean Girls?

idk if thats a stupid question cause idk how realistic those were in the movie... but im trying to gain weight and im only 16 with a rediculous fast metabolism which is extrememly frustrating... i need something like those bars to help me gain it faster than it burns off. if you know of anything along those lines to eat or drink regularly to gain weight, please let me know!! thanks =)

There's something called a Plumpy’nut bar which was used to help famine relief and starvation which is used in Africa it's high in vitamins and helps gain rapid weight gain.
