I can't answer your question directly, but I can direct you to a site where you can get hold of many natural products that will give you a massive lead over most people when it comes to your own health and fitness? I do Search Engine Optimization for a Charity who raise money for children suffering from Cancer , by using all of the profits from the sale of natural and forgotten remedies to help such children and their families.
One product that I would personally recommend for weight loss is Apple Cider Vinegar which has a great many medicinal uses including weight loss . However it is important to buy this product in it's purest form. The Apple Cider Vinegar that Bobby's Healthy Shop sell is 100% pure with "mother" and very few other places sell this product in a form as pure as this.
Bobby's Healthy Shop also sell a great many other products that are all used to improve health and fitness in one way or another. Why not at least check out the website and read the information there, and then make up your own mind, don't just take my word for it.
