Wow. Registered Dietitian & Nutritionist Lisa De Fazio, MS, RD tells HollywoodLife.com EXCLUSIVELY that ‘Teen Mom 2’ star looks unhealthy in her shockingly thin new Instagram post. Find out more right here.

“Leah Messer looks as though she has lost at least 15lbs,” Lisa tells HollywoodLife.com EXCLUSIVELY. Please note that although Lisa has not treated Leah directly, she is a registered dietician and nutritionist. “In older photos, she appears to weigh 120 and now in the most recent pic of her wearing a bikini, she looks to weigh 105 lbs.”

Lisa continued by telling HollywoodLife.com that Leah looks “unhealthy,” especially because “her bones are protruding.” As you can see in the photo, Leah’s clavicle and rib cage are visible through her skin due to the weight loss. “A healthy weight for someone her height, 5’4″, would be 120lbs, so she definitely appears very underweight.”

As for what could be causing Leah’s new skinny body, Lisa explained that there are actually a few things that could be contributing to the Teen Mom 2‘s weight loss. “She could have lost the weight by not eating enough and/or exercising too much,” Lisa explained. “Unless there is a medical condition that we don’t know about. Anxiety can lead to weight loss because some people lose their appetite when anxious or stressed. Some medications also cause weight loss.”

It’s no secret that the past year has been troublesome for Leah with a non-stop custody battle, a second divorce, and even a stint in rehab. Not to forget that she has also lashed out at MTV for the way they’ve portrayed her on recent episodes of TM2.

No matter what is causing Leah’s weight loss, it could only be the beginning of even more health issues, according to Lisa. “Being underweight can lead to heart issues, iron deficiency, and decreased immune function making her more vulnerable to getting sick. She can gain weight by eating more calories, protein shakes, 3 meals/day plus snacks,” Lisa explained, offering some tips to Leah and others who might be struggling with keeping their weight at a healthy level.
