Before you test the waters with any supplements, you need to look at your diet and go from there! Your biggest accomplishments with weight loss are going to happen in the kitchen, not in the gym.
So the easiest thing to do is look at what you eat on a daily basis. Do you know what your caloric baseline is? You'll need to know what you need to eat in order to maintain your body weight, gain weight, or lose weight. Then take a look at what you can eat and make a daily meal plan and watch the fat melt off of you ;)
Cardio will help as well in burn some extra calories so keep up with that as well.
Good luck with your fitness goals
