Metabolism booster/Fat burner

I’m thinking about ordering a metabolism booster or fat burner to help my weight loss get started. i started going to the gym about a month ago and have stayed at a weight but not lost :( I’m only looking to lose about 10-15 lbs and am doing noninvasive laser lipo on my thighs bc they are a hard area for me to deal with. I’ve saw a few on amazon with good reviews but wanted to ask you ladies as well for any info and or tips
