Glass waist beads gauge changes in weight. Instead of stepping on a scale, one can use them to stay aware of any weight gain or loss in the abdomen. Waist beads don't stretch. If weight is gained, the beads will sit higher on the waist or feel tight. Conversely, they will have more slack and sit lower if there is weight loss. This visualization is crucial in motivating a person's continued weight loss journey. The beads work great as natural waist trainers. They may slightly pinch the belly reminding one of bad posture, bloating, or to remain conscious of better eating habits. Either way, love yourself through this journey!
