Keto
This is a good answer. Also let me add, be careful with cross fit, as it seems super intense and there is a good chance one night get injured first
Major props to you at 15% body fat

Try low carb instead. Less than 100g net carbs per day. Or even better - try keto, which is less than 20g of carbs per day. Give it a couple months. You won’t regret.
The one that is closer to you
First, figure out what your maintenance caloric intake is (the amount of calories per day that if you ate you would stay the same weight, hint it’s very likely not the standard 2,000 that everything is based off). From there, figure out the best way for you to get your net intake below that amount (could be eating less calories, or burning more).
Seriously, just exercise (any kind) and eat more conciously. That's all it is.
Personally I prefer the Watermelon Hypothesis over the orange theory.
I love you.
Definitely not a cheeseburger!
20% is exercise. 80% is diet.
