Fans of Sobinoff recently voiced concern over the reality star’s sudden fluctuation after she shared a photo of herself looking particularly slim on Instagram.
According to The Daily Mail, one fan wrote: "[She's] looking so thin and sick, hope all is OK. Hopefully, you can put some kilos back on. This does not look good on you."
Another commented: "No-one is being nasty or horrible, just stating the facts. Lizzie has a warm, generous soul, however, I would be worried if she was my daughter. She doesn't look well, but if she's happy that's all that matters."
Recently, Martha told the Daily Mail that the reality star has an autoimmune disease that provokes weight loss.
"I don't think there is anything to worry about. I think she looks great and wasn't it a year ago that people were calling her fat?"
"And now they are saying she's too skinny. Just leave her alone, it's her body and she can do what she wants with it... I'm pretty sure she was quite open about having health issues, so maybe that has something to do with it?" Martha continued.
"Maybe instead of everyone just saying, 'Oh she's [too skinny],' dig into it a little bit more and you'll learn or find out the truth."
