The doctor looked at his screen, then back at me. ‘The thing is, Big Man,’ he said, ‘if you don’t change your behaviour around eating, I guarantee you won’t reach the age of 30.’ Those words hit me like nothing I’d ever experienced before. I couldn’t speak – I just nodded. Deep down, I knew my lifestyle wasn’t healthy, but I never imagined things had gotten that bad.

It was a concerned comment from my boss at the coffee factory where I worked that led me there. One day he found me drenched in sweat and struggling to catch my breath while I wiped down the machines. ‘You’re not looking well, John. I think you should see your doctor,’ he said. He was right. I was exhausted all the time and often felt like I could fall asleep mid-shift.

The wake-up call I couldn’t ignore

I thought it would be a routine check-up – but it turned into something much more serious. My GP immediately sent me to hospital by ambulance.

Tests revealed my heart had become enlarged due to my weight, putting me at serious risk of heart failure. I was also diagnosed with prediabetes, high blood pressure and sleep apnoea. At just 20-something, I was told I was heading towards an early grave.

Food was my comfort

After leaving school at 16, I’d taken a cookery course at college. I’d never put the skills I’d learnt into practice, though, and relied heavily on takeaways.

During the week, breakfast and lunch came from the food van near the factory: the Scottish specialities Lorne sausage and tattie scone to start the day, followed by cheesy chips with curry sauce. Dinner was usually an Indian takeaway. I had all the symptoms of depression, but instead of turning to drink or drugs – something I’d seen other people do – food was my chosen medication.

With my health declining, I moved back in with my mum. She was understandably worried. ‘Sometimes when you’re sleeping, I can hear that you’ve stopped breathing,’ she told me. ‘We need to do something before it’s too late.’ Seeing how concerned she was, I knew I had to make a change.

The first thing I did was tell my boss that I simply wasn’t fit to work, and I’d be concentrating on changing that. The second thing was agreeing to go with Mum to her Slimming World group. I was terrified about that first session – I even crash-dieted beforehand, which turned out to be a mistake.

A dramatic first weigh-in

My first group session started well enough. The Consultant, Carrina, was very welcoming and explained how Food Optimising worked – and then it was time to weigh in. I stepped on the scales… and that was the last thing I could clearly remember. The room swam around me and I staggered back into a chair, my chest tight and nausea sweeping over me. ‘Call an ambulance!’ I heard someone say, and I was vaguely aware of Mum’s frightened face peering down at me. Rather than wait for the paramedics to arrive, though, a kind couple from group drove me straight to A&E. 

Thankfully, it turned out not to be a heart attack – in fact, the hospital consultant put it down to the fact I’d eaten so little over the past week. ‘It’s great that you’re trying to lose weight,’ he said, ‘but it’s not going to happen overnight.’ It was a scary moment, but also a turning point. I realised this had to be done properly.

I couldn’t help feeling embarrassed at having caused such a drama. I needn’t have worried, though – everyone was just relieved that I was OK, and I could see that Carrina and the other members were rooting for me. 

For the first time, I had structure. I swapped my usual greasy breakfast for Weetabix, yogurt and fruit, and ditched the food-van lunch for healthier options like a chicken salad bowl from the local cafe. In the evenings, I started cooking proper Slimming World meals – my favourites being doner kebab and creamy Cajun chicken pasta. I soon discovered that I loved planning and cooking my meals, something I’d never expected.

The group support made all the difference for me. There’s nothing like it. I thought it would just be about getting weighed, but it’s so much more than that. There’s loads of encouragement and practical help every week. With the support of Carrina and the group behind me, I began to believe change was possible.

Small steps, big changes

After losing 5st (31.8kg), I felt ready to move more. At first, even a fairly short walk to the shops took me an hour. But I didn’t give up. Following Slimming World’s active lifestyle programme, I kept going – and eventually that same stroll took just five minutes.

As the weight came off, everything changed. My confidence grew, my energy returned and the depression I’d struggled with for years began to lift.

By December 2024, I’d lost more than 15st (95.3kg). My old clothes hung off me – my Rangers football top looked like a tent! For the first time, I actually enjoyed shopping, and I started building a wardrobe I felt proud of.

When I reached 10st 13lbs (69.4kg), I felt I’d hit the right weight for me. Carrina introduced me to the Slim for Life programme, which helped me focus on maintaining my weight while still enjoying life. It gave me the confidence to keep making healthy choices long-term.

Proving the doctors wrong

The most powerful moment came when I saw my doctor again. He didn’t recognise me at first – then he checked my notes and smiled. ‘You’re a changed man,’ he said. ‘You should be very proud.’ Walking out of that appointment, I felt on top of the world.

Today, my health issues are under control, and I feel fitter and happier than ever before. Celebrating my 30th birthday at my Slimming World group meant everything. A few years ago, I didn’t think I’d get here. This whole experience has completely changed my life. I’ve gone from being told I might die young to feeling healthy, confident and excited for the future.

Slimming World IS for men!

She says: ‘Our groups make a real difference to long-term weight loss. The accountability, shared ideas and practical strategies help members like John create lasting habits and achieve truly life-changing results.’

This Men’s Health Week (15th-21st June), men are being encouraged to prioritise their wellbeing. John – who has maintained his weight loss for over two years now – says he hopes his journey will inspire others. He says: ‘I was terrified walking through those doors for the first time, but it’s the best decision I’ve ever made. In the beginning, I never thought I’d get this far. If you’re thinking about it, just take that first step. It could change your life like it changed mine.’
