Weight loss

So I’m currently at the highest weight I’ve ever been at and I am not happy about it or the way I look. I don’t feel comfortable in anything that I wear. I’m not the kind of person that eats out all the time maybe like once every two weeks, I have a job where I’m moving around but I don’t know what’s making me gain weight. I was wondering if anyone had any weight loss tips. Willing to try anything. I’m also on birth control the pill so I don’t know if maybe that’s it ?

If you read this far, thank you ! Any help is much appreciated
