Weight loss catalyst

Hey everyone, I'm 24F with BMI of almost 30. I gained nearly 15-20 kg a year ago due to sedentary lifestyle. But now I'm trying to lose weight asap for upcoming wedding in my family. I am currently on calorie deficit of 1100-1200 kcal per day with average 20 minutes of zumba workout daily from last month. As there is no considerable change in my weight I want to add some weight loss supplements. Please share some suggestions.
