Lauren has spoken about her battle with skin cancer before, watch below.
In the emotional post to her Instagram stories, the 31-year-old reveals the ups and downs of her weight changes, and shares confronting photographs of how her body has altered over time.
"I've been chubby ... I've been skinny ... I've had a six pack," she shared.
She explained that her physique has changed over time due to factors such as mental health, medication, chronic pain - as well as painful past relationships.
"There have been times I chose not to eat because a boy told me I was too fat," Lauren said in the candid post.
Talking about her journey, Lauren added: "Sometimes I eat more when I'm depressed, sometimes I have no appetite because I'm anxious."
"Sometimes I can't exercise as much as I'd like to because of pain. Sometimes I've been on medication which caused me to gain weight," she shared.
Ending on a positive note, Lauren said: "The best thing about getting older is you learn to love yourself no matter what shape, size or weight you are. You give less of a s**t what others think of you and you learn to accept and embrace the skin you are in."
We couldn't have said it better ourselves.
