Dr. Deep Goyal, Surgical Specialities Consultant, ARTEIMS explains that plastic surgery procedures such as liposuction and tummy tuck have a very little role in weight loss. These surgeries are not exactly weight loss surgery, but are contouring surgery. These surgeries actually restructure the heavier parts of the body. They do not cause significant weight loss, but slightly. If the person starts following his unhealthy eating habits, he will regain the loss immediately. Therefore, it is advisable to follow a proper and healthy diet plan to lose weight rather than undergoing surgery.
