Light cut fiber is a kind of health care product that claims to be used for weight management. Its manufacturer claims that the product strictly abides by the rules of the big health market and is produced with food-grade raw materials without adding any drugs and hormones. Zero2IPO Fiber claims that all the raw materials of its products are food grade, and there are no drugs or hormones. However, according to some reports, there may be false propaganda problems in its products. For example, optical fiber carving students claim that their products can "burn fat, shape and lose weight", but in fact the effect may be very limited and may even have a negative impact on the body. Consumers should be cautious before using any products that claim to help lose weight, especially those that claim to achieve weight loss through special methods or formulas. These products may not be verified scientifically enough, or their claimed effects may not be realized. We are considering using light-carved fiber or any of its slimming products. We suggest consulting a doctor or dietitian before use, and taking reasonable diet control and exercise to achieve the goal of healthy weight loss.
