"Teen Mom 2" star Kailyn Lowry seems to be gaining weight again after boasting a 45-lb weight loss last year. The young mother underwent plastic surgery and got slimmer to appease now ex-husband Javi Marroquin, she says. After their divorce, is she running to food for solace? Is she comfort eating because her young son Isaac Rivera prefers Javi's company to hers? Lowry's known for yo-yo weight gain and loss. Since the split, she appears to be nearing obesity level. What's eating this teen mom?

Kailyn Lowry on 'divorce diet'?

In relationship breakup, people often either lose weight or put pounds on, depending on their food relationship.

Many have famously said they're slimmer thanks to the "divorce diet." The pain of losing someone may kill appetite. If infidelity is involved, victims report feelings of nausea, vomiting and other psychosomatic illness. But the reverse is also true. The reality television "Teen Mom" celebrity has admitted to a food addiction. So it stands to reason that Lowry would also turn to comfort eating in depression, anxiety, or stress. Mama June Shannon, another reality television star from "Honey Boo Boo" claims weight loss from changing her relationship with food.

Kailyn Lowry on scary body size merry-go-round

The "Teen Mom" has reported three separate incidences of significant weight loss on Instagram.

This could be down to yo-yo dieting. In an effort to get or stay thin, celebrities will often crash diet. It could also be caused by an eating disorder. Anorexia and bulimia are the most common ones but obesity stems from disordered eating as well. Are body image issues behind this, and is Javi Marroquin behind body size fluctuations?

Javi throws Kailyn Lowry under the knife?

A year ago, Lowry flaunted massive plastic surgery changes to her body. She had a tummy tuck and butt implants (a.k.a. a "Brazilian butt lift"). She also had liposuction done, and possibly a breast implant procedure. Kailyn showed off her new look, and its reported that Javi very much approved.

He may have even encouraged the makeover. And if he was pushing for cosmetic surgery, you can bet he was nagging her to lose weight too. So with him out of the picture, is the "Teen Mom" going back to old habits? Was she starting to gain weight again and he didn't like it? Is she rebelling against spouse-defined body requirements?
