I'm doing Pilates 2-3 times a week. Will it be effective for weight loss?

I started Pilates recently because I want to manage my figure and lose weight.

I am currently going consistently about 2 to 3 times a week, and I feel like my posture is improving and my body is gradually becoming firmer.

But I'm curious because it seems like there hasn't been much change in my weight compared to what I expected.

Will doing Pilates only 2-3 times a week help with weight loss? Or would it be more effective to combine it with walking or other cardio exercises?

If there are any of you who have actually experienced weight loss or body shape changes from consistently doing Pilates, I am curious to know how long you attended and whether you also followed a diet!
