A woman who was ashamed of her size has now spoken of her weight loss journey.
Rebecca Bennett-Formstone, 23, bought a corset to hide her 15st frame after becoming ashamed of it.
She wore it during meals out or at work and admits it was so painful she couldn't eat or sit down.
However, experts have warned about wearing corsets as it could deprive your body of oxygen.
Some say it can reduce lung capacity by up to 60%.
But soon the business owner, from Coventry, ditched the corset and began a low-carb ketogenic diet.

Rebecca said: "I bought a waist trainer because I was told it would give me amazing curves. I began to wear it because I felt so self conscious of my own frame.
"I'd wear it two or three times a week – when I'd go out for a nice meal or under my work uniform. But it was so tight I felt like I couldn't sit down and I wanted to take it off after 30 minutes.
"I didn't notice my weight as much until I got engaged and then I became more conscious that I was going to have to wear a big wedding dress if I didn’t lose weight.
"I heard about the keto diet on Pinterest and thought I'd try it because I had nothing to lose other than a bit of weight.
"Within the first week I'd lost 4lbs already and I was shocked that it was working for me when the other diets hadn't. Now I feel so confident and I can finally dress how I want without straining myself in a waist trainer."
Rebecca began gaining weight in 2018, after feeling the need to snack and treat herself to a Starbucks every day due to her retail job.
Then when she got engaged to her now-husband James, 26, she tried to follow diets, but nothing was working.
She turned to waist trainers to help build her confidence before she eventually grew tired of them.
The business owner added: "I always wanted to wear baggy clothes so I didn’t have to wear the waist trainer because if I wore anything tight, I would have to wear it, and then I couldn't eat or sit down – it was horrible.
"I wore it once or twice a week but as I got a bit bigger I had to stop because it became so unbearable, I could only wear it for three hours."
She came across the keto diet and began to reduce her carbs after deciding she didn't want to use the waist trainer anymore.
Rebecca managed to shed almost 2st in two months and had her wedding dress altered by an inch-and-a-half on the bust.
She continued: "It was really quite quick – I didn’t expect to lose that much when I'd only wanted to slim up a little bit before my wedding.
"I felt really confident on my wedding day, especially when it came to taking the photos because I didn't feel like I had to tuck myself in to try and look tiny."
In total, Rebecca dropped 5st in less than a year, now weighing a healthy 10st.
Now she shares her weight loss tips and success with her Instagram followers, where she has over 12,500 fans.
She concluded: "I've got loads more energy now and I feel like I can't do enough things, I'm also a lot more sharp.
"My husband always said he never remembers me looking like I did when I show him the 'before' photos, but he's been really proud and supportive of my journey.
"Before, it was so difficult to model my own clothing brand because I'd hate every picture I took for the website.
"But now that I've slimmed down, I've gained the confidence to be able to do my job a lot more efficiently and I feel amazing."
