We want you to slim down—and stay slim. A “diet” is something you do to your body; Bios Life Slim™ is something you do with your body. You’re gradually training your body to burn fat, not store it. It usually takes about three months for this process to become permanent. Most users of Bios Life Slim™ begin “feeling better” within days, and report that a reduction in size starts less than 30 days later.
