The LeanCaps is centered around the concept of "lean nutrition," which prioritizes nutrient-dense, whole foods while minimizing processed and high-sugar options. The diet incorporates a proprietary blend of natural ingredients, including plant-based extracts, vitamins, and minerals, designed to support metabolism, curb cravings, and promote fat burning. These ingredients are often consumed in the form of capsules, making it convenient for individuals with busy lifestyles.
