certain weight loss spells help more with mental, it will help motivate you when you laze around, or feel like crap. but it won't shed those pounds faster, with all magick, you need to put forth some effort.
look into an illusion spell. it won't make you hansom, but when people look at you, you will seem more hansom to them.
no spell can make one popular. as someone who was once popular i don't see the appeal, you sit around with people talking about what's in, acting and dressing the same, in the hopes you won't be singled out and tossed aside. trust me, i was far happier when i was with my unpopular friends. if you want to be popular, imitate what they are into, that's the best advise i have if you want to be popular, but trust me, it's overrated. once highschool is over, you'll never have to deal with it again... unless you're running for a seat in the government.
