No supplements or special diets will help you lose weight quicker, the only way is to have a calorie deficit(eating less calories than you burn, I would recommend trying for between -500 and -1000 calories. The internet will give you an approximate daily caloric expenditure just based on your height, weight, age ect, would probably work out to be between 2000-2500 for you. Take it as a high end estimate and eat around 1500 calories in a day. Measure the quantities of your meals or if you're eating in a restaurant find out how many calories are within your item. I personally will intermittent fast so I skip breakfast and eat an average of 500 calories in my lunch and dinner each the rest of my allowance will be a protein shake and a couple snacks.
I would recommend eating high protein low carbs and if you're having carbs try having complex ones like sweet potato, whole grains, brown rice, corn ect. This will fill you up and prevent you from going over your calorie budget. Protein shake works really well for me, 150 calories but 35 grams fo protein and very filling.
Other filling things: Diet pop, carbonated water ect.
The main battle is your diet but you can help by exercising, it won't make much difference if you do it once a week but if you go 5x a week or more it can really help your deficit. I personally do a combination of weightlifting then High intensity interval training(this one really helps you burn calories in a quick period of time) Get a heart rate tracker for your workouts try to keep your HR above 150.
