The 42-year-old had tried calorie counting and the keto diet, but with no luck.

After seeing other people's success using Mounjaro, she decided to try it herself, ordering them privately through Asda Pharmacy, costing £180 per month.

In just seven months, she went from 14st 3lbs to 9st 7lbs, with a further stone lost gradually.

But while she is overjoyed with the results, it has caused tension in her marriage.

“I knew my husband would worry and might try to talk me out of it,” the HR vice president, from Berkshire, said.

“So I decided to go ahead on my own.

“For me, it was a medical decision; no different to taking ibuprofen.

“He then asked me one day if I was on ‘those jabs’ and when I admitted I was, he wasn’t happy.

“Not because of the medication itself, but because he felt I had been dishonest.

“I didn’t, and still don’t, see it that way.

I've lost 3 stone in 8 months on fat jabs - there's a common error new starters are making & it means nasty side effects

“It was simply a solution to a long-standing problem.”

Kym, whose cravings and over-indulgence of cheese and sugary items were the cause of her weight gain, decided to purchase the “skinny jab” following her dad’s sudden health downturn.

He suffered a heart attack out of the blue, despite being in good health, and this gave her a wake-up call.

She switched up her diet of pizza, chips and sweets for fish, vegetables and fruit.

Kym also got back into exercise, making time to regularly go swimming, do pilates and go to the gym to lift weights.

She’s now on a maintenance dose of the jabs and to keep her weight loss on track, she’s working with on one of their structured plans.

Everything you need to know about fat jabs

Weight loss jabs are all the rage as studies and patient stories reveal they help people shed flab at almost unbelievable rates, as well as appearing to reduce the risk of serious diseases.

Wegovy – a modified version of type 2 diabetes drug Ozempic – and Mounjaro are the leading weight loss injections used in the UK.

Wegovy, real name semaglutide, has been used on the NHS for years while Mounjaro (tirzepatide) is a newer and more powerful addition to the market.

Mounjaro accounts for most private prescriptions for weight loss and is set to join Wegovy as an NHS staple this year.

How do they work?

The jabs work by suppressing your appetite, making you eat less so your body burns fat for energy instead and you lose weight.

They do this my mimicking a hormone called GLP-1, which signals to the brain when the stomach is full, so the drugs are officially called GLP-1 receptor agonists.

They slow down digestion and increase insulin production, lowering blood sugar, which is why they were first developed to treat type 2 diabetes in which patients' sugar levels are too high.

Can I get them?

NHS prescriptions of weight loss drugs, mainly Wegovy and an older version called Saxenda (chemical name liraglutide), are controlled through specialist weight loss clinics.

Typically a patient will have to have a body mass index (BMI) of 30 or higher, classifying them as medically obese, and also have a weight-related health condition such as high blood pressure.

GPs generally do not prescribe the drugs for weight loss.

Private prescribers offer the jabs, most commonly Mounjaro, to anyone who is obese (BMI of 30+) or overweight (BMI 25-30) with a weight-related health risk.

Private pharmacies have been rapped for handing them out too easily and video calls or face-to-face appointments are now mandatory to check a patient is being truthful about their size and health.

Are there any risks?

Yes – side effects are common but most are relatively mild.

Around half of people taking the drug experience gut issues, including sickness, bloating, acid reflux, constipation and diarrhoea.

Dr Sarah Jarvis, GP and clinical consultant at patient.info, said: “One of the more uncommon side effects is severe acute pancreatitis, which is extremely painful and happens to one in 500 people.”

Other uncommon side effects include altered taste, kidney problems, allergic reactions, gallbladder problems and hypoglycemia.

Evidence has so far been inconclusive about whether the injections are damaging to patients' mental health.

Figures obtained by The Sun show that, up to January 2025, 85 patient deaths in the UK were suspected to be linked to the medicines.

This includes nutritional guidance and dedicated personal trainers. Kym now feels more confident than ever before, though says she’s struggling coming to terms with her new body.

Especially her boobs.

She added: “I used to have quite big breasts and I had lower back pain when exercising.

“Now, though, I’ve lost them both.

“It’s been really hard coming to terms with. “I’ve had to book myself in for breast implants and an uplift.

“I’ll maintain my weight for a year before doing it, though.

“I also have loose skin, so I’ll look into getting a tummy tuck, too.

“But I can’t wait to get back into a bikini once again, as I haven’t been on holiday in forever.

“Mounjaro didn’t just change the number on the scale; it’s given me control over my health and outlook on life again.”
