A well-known celebrity who has lost more than 50 pounds using a certain weight-loss program is the spokesperson for the product. Mariko knows the celebrity has really lost the weight because she has appeared on numerous shows lately. The program also helped Mariko’s cousin lose weight. Mariko’s doctor has told her that she needs to lose 10 pounds to be within the healthy weight range for her height. Should Mariko use the weight-loss program? No. Weight-loss programs should be used only by people with extreme weight-loss goals. Yes. If it worked well for the celebrity and Mariko’s cousin, it will work for Mariko. Maybe. Mariko should check with her doctor to see if the program is safe and effective. It depends. If Mariko has the same body type as the celebrity, then it is okay.
