What is your method to lose weight?

I'm 5'6 and weigh 134 Ibs. Right now I need to lose some fat to look good in my bathing suits this summer. So my question to you guys, is how did you lose weight? Did you run?, Did you fast? I'm just looking for how you guys lost weight and if it worked for you. Thanks, and have fantastic April!
