Writing on her blog Nesting Story, mum-of-four Venditti explained that she had struggled with her weight - and her confidence - ever since she was young.
But in college, she explains, she learned how to "lose 10 pounds scarily fast" and, while she wouldn't ever say she had an eating disorder, she knew that her obsession with her weight wasn't coming from a good place.
She explained simply: "I felt I had to punish my body."
Venditti fell pregnant twice, gaining 50lb with each baby, but she found herself able to shift the pounds easily after giving birth.
It wasn't until she was expecting twins that Venditti had to learn how to accept a very, very pregnant version of herself. "I couldn't wrap my mind around how enormous I was going to get," she writes.
"I finally made the decision that I would disassociate my body from my mind during my twin pregnancy and think of my body as a vessel. Guess what… that worked!
"In fact anytime I’d start panicking about my size I would say to myself 'you are a vessel, you are a vessel'. It became my mantra."
Despite this, Venditti found that she felt unhappy with her "bruised and battered" postpartum body.
"My distracting enormous but adorable baby bump had been deflated and I was left with mush, bruising, swollen ankles and healing from a c-section."
Yet, while she felt sad for her body, Venditti learned to be grateful for everything it had done for her - and finally discovered how to love herself, belly and all.
She wrote: "It had safely created two humans and carried them for 37 weeks and 4 days.
"Anytime I start doubting my new curves or war wounds I look around the room and ask myself, how many other people in this room grew two people inside their body at once?"
