Tracking kcal?

I just started on 2.5mg of Zepbound after being almost obese and besides lifting weights, eating around 1500kcal and an average of 10K steps nothing has worked. I also tried more kcal and less - yes! But nothing, absolutely nothing has worked. I eat very healthy and my amount of protein is 120gr/day and 27gr of fibers.

I just started the med and I keep wondering if I should lower my kcal. I keep reading all these post ppl tracking and eating 1000-1200 recommended by their doctors. I know ppl say just listen to your body but I want to make sure I still eating the right amount of protein and not doing something super crazy to my body drastically.

Any advice is very appreciated!

I'm 41 years old, 178 pounds and 5.4
