Losing weight

Anyone have any good suggestions on how to lose some weight a bit faster or better ..my boyfriend says I don't need to, he says "woman, I would love you even if you were skinny or big. I don't love you just for your physical appearance, but I love you for you." I really wanna lose some weight though I dont feel as happy with my body anymore or confident. I am 19 on the 23rd of Dec and I weight like 180.9 pounds. I need help or some friendly advice. much appreciated. xo
