Transferred fat from one region of the body to another is like planting seeds in a garden Some seeds grow and some don’t. Unlike seeds, which given proper sunlight and water will likely thrive, the factors surrounding what gives fat cells the best opportunity to survive following transfer is not completely understood. Results vary from person to person despite consistency in technique. In my estimation it is quite common for up to 40% of the fat may not survive transfer. Despite these numbers, the surviving fat in combination with targeted liposuction of the waist makes for excellent results.
