In Thursday's premiere episode, fitness fanatic Michel Marley clashes with self-described "big beautiful woman" Kristy Love when they are forced to live with each other for eight days.

"I believe that the way that Kristy is glamorizing being obese is not acceptable," Michel told ET.

"I'm not obese," Kristy interrupted. "I'm overweight."

Kristy weighs 335 pounds and is 5 feet, 3 inches tall, while Michel is 120 pounds and is 5 feet, five inches tall.

"I'm going to put her fat ass in her place," Michel says in a clip from the show. "I'm not taking any of her excuses."

Michel explained her harsh words, saying, "I'm not fat-shaming in any way. It's just like a tough love with your children."

Ironically, it's Michel who is the most self-conscious during a photo shoot. While Kristy flaunts her figure proudly in front of the camera, Michel frantically taped up her waist in fear that she wouldn't look her best.

"She should've used that [tape] on her mouth," Kristy quipped.
