And for several months, only her husband was aware of how she truly shed the pounds.The customer service manager admitted: 'I was a secret jabber. 'There's a lot of judgement around weight loss injections, so I wanted to limit who I confided in - just to avoid having to justify myself.'Karen began researching weight-loss injections on TikTok, where she found positive stories from people who had lost significant amounts of weight. But she was wary of telling friends and family, particularly after years of failed diets and conversation about her weight.

'There was also a lot of mixed opinion online at the time. The media coverage was often quite polarising, and friends and family all seemed to have different views about weight loss medication.'As the weight began to come off, Karen continued to keep her treatment under wraps, telling people she was simply adopting a healthier lifestyle. She even hid her medication under the vegetables in her fridge whenever visitors were expected. She said: 'I would get the odd comment [about using jabs], but nobody outright guessed. I just kept mentioning that I was starting a healthier lifestyle, which wasn’t a lie.'I was really careful where I stored the jabs in the fridge [to avoid people seeing them], and I would be extra careful if I knew people were coming round.'My favourite spot to hide them was in the vegetable tray, under all the veg!'According to Karen, her weight had gradually increased over the years as food became a source of comfort.

She shared: 'As a family, we'd celebrate with a nice meal, and if I was feeling stressed, sad or had simply had a difficult day, I'd often turn to food for comfort.'I don't think I even realised I was doing it at the time. It had just become my normal way of rewarding myself or lifting my mood.'She added: 'I rarely cooked dinner at home – my husband and I would go for a couple of drink after work each night and couldn’t be bothered to cook, so we’d order a takeaway instead.'Those habits were convenient, enjoyable and easy to fall into, but over time they all compounded.'Weeks turned into months, months into years, and the weight gradually crept on without me really noticing.'
