"You can get very caught up in these shows -- especially young girls who are still building their self-esteem," said Leslie Goldman, the author of "Locker Room Diaries: The Naked Truth About Women, Body Image."
"These girls want to be pretty and on television, and this show gives them the opportunity," said Goldman. "But there is a clause: They have to drop a lot of weight."
Goldman, who said that she respects a lot of MTV's programming that focuses on teen issues -- such as "True Life," which follows teens as they cope with issues like peer pressure and divorce -- added that she worries "Model Maker's" time frame for weight loss is too aggressive.
"In our culture, it is a numbers game: How much do you weigh, how big is your chest and how slim can you get your hips?" said Goldman. "If a woman has a dream of being a model, it's feasible that she could lose weight and do it -- but not necessarily in three months."
Having struggled with weight issues as a teen, Goldman said that she's also concerned that young girls trying out for the show may be hurt by casting directors telling them that they'll be pretty -- but only if they get rid of some excess fat.
"It's very difficult and crushing to have someone look at you and say you're very pretty but you'd be beautiful if you were 30 pounds lighter," said Goldman.
"When you're talking about losing that much weight, it sounds like health is the last thing on their minds and cosmetics is the first," said Ayoob. "And when you're talking about weight loss, health should be the first priority."
For Debbie Then, a social psychologist who specializes in women and appearance, news that another show about weight issues might materialize wasn't particularly surprising.
"This show is just capitalizing on what we already know: You can't blame them for doing it," said Then.
"For women, the bottom line is that, cradle to grave, you have to look pretty," said Then. "And pretty for women and attractive for women means youthful looking and thin."
"I'm not at all surprised that this show is happening or that it will be successful," said Then. "Unless they stop getting ratings they won't take these [types of shows] off the air."
"These are the shows people want to watch."
