Trying to lose weight

Dami • makeup, makeup, makeup!
So ive gained ALOT of weight living in Georgia. When I first moved here i was 150 now im 190. Yea 40 pounds 😩. So I want to get back down to 150. Is there any tips you girls/women would like to give me on losing weight. Im planning on going hiking and running. I looked up some ways to exercise and focus on my legs, tummy, and butt. I want to try a new diet for good. So any tips will be great. Thank you!!!
