How did you lose weight?

It's about that time to seriously turn my life around. I've found a form of exercise that I actually enjoy (Zumba), but I feel like I need to change my diet to make my effort worth it. I looked at r/loseit and r/keto, but there is a lack of POC on those subreddits.

My family has never been one to watch what we eat, so I've always just ate what was given in front of me. I'm not much of a cook, nor do I really enjoy doing it so I've had no say in that matter. I'm thinking of the keto diet since it seems that a lot of people have had success with it, but my first thought was "I can't eat bread?!?!?!".

I guess I just wanted to hear from some black women who have successfully jumped the hurdle of getting to a healthy weight or those that are still on the journey to their goal. What did you do? What type of things did you eat? What worked for you and what didn't work?

Edit: Thank you everyone for your advice :) Sorry that I didn't reply back to everyone but your everything that you've said makes a lot of sense and I'll definitely keep it in mind. It seems that I'm on the right track, there and your advice gave me more information keep it going.
