Inverted Triangle Weightloss

So I’m trying to lose weight. When I was in my teens, I thought I have an hourglass shape. When I gained weight I realized that I am an inverted triangle. I don’t have big hips and not gaining fat on my butt. I mostly gain weight on my arms and stomach area.

To people with inverted triangle body who is losing/lost weight. Could you share some tips on how to lose weight and how to properly gain muscle to give hips some definition and get lean muscle on the arms?

Everyone’s input is appreciated
