How does Bella work for weight loss?

Could you please explain in detail how Bella contributes to weight loss? I'm particularly interested in understanding the mechanisms behind its effectiveness, such as whether it increases metabolism, reduces appetite, or has other specific effects on the body. Additionally, I'd like to know if there are any clinical studies or scientific evidence to support its claims of promoting weight loss. It would also be helpful if you could share any potential side effects or precautions that users should be aware of when incorporating Bella into their weight loss journey.
