Are there any good diet supplements that I can take while exercising and eating a balanced diet?

Hello Maypure members~ I finally started working out in earnest this week by dragging my heavy body out of the gym ㅋㅋ I even quit my habit of ordering delivery food as a late-night snack every day and I've been eating salad and chicken breast diligently, but unlike when I was in my 20s, the speed at which I'm losing weight is really slow and I'm really losing motivation ㅠㅠ So I'm looking for a product that can act as a booster, but there are so many types that I'm leaving a question! Is there a diet supplement that you all take while working out that you think is really worth the money?

Actually, I have a sensitive stomach, so I used to suffer from a really bad stomachache after taking some popular pills in the past. ㅎㅎ;; So this time, I'm looking for a diet supplement that has the mildest ingredients and doesn't have too much caffeine, so it doesn't cause side effects like heart palpitations. I can't figure out whether Garcinia, which blocks carbohydrate absorption when taken before meals, is good, or whether it's better to take it before bed to increase basal metabolic rate. ㅠㅠ

Of course, I know that I shouldn't rely on medicine alone and that exercise and diet are essential, but I want to get some help like a magic item every once in a while when I hit a plateau. ㅋㅋ If any of you MePyus have any diet supplements that have been effective in helping me go to the bathroom comfortably without side effects and changing my body, please leave a comment and I would really appreciate it! I also welcome diet supplements in powder form that you can mix with water and drink like a drink, not pill form. ㅠㅠ Everyone, let's all gain weight today and succeed in dieting this spring. Fighting~~
