Weight-loss diet programs are extremely popular. These programs ask participants to follow a strict regimen that either limits the calories participants take in or limits the type of food participants are allowed to eat for a specific amount of time. Programs that offer a regimen that limits the calories participants take in see better results than programs that limits the type of food participants are allowed to eat. This is because these programs teach people how to regulate their calorie intake, regardless of what food they eat. Participants who strictly follow this type of program see positive results especially if they also exercise a moderate amount. Which of the following statements, if true, would most strengthen the above argument? a. Participants who do not exercise are not able to achieve their full weight loss goals.
b. Participants feel hungry at the beginning of the program.
c. Participants have a hard time maintaining their new weight.
