Chris Boyce, 68, from Horley, Surrey, says a straightforward dietary change cleared his extreme bloating within 24 hours. The problem began in April of this year, after he had devised a heart-health diet using AI.
Heart bypass and diet complications
Boyce underwent a triple heart bypass in 2023, but complications arose in 2025 when one of the replacement arteries became blocked. Late last year, he used AI to create a diet he believed was tailored to support heart health, but it soon triggered problems elsewhere.
He was assessed by numerous doctors across various departments, including cardiology and urology, but none could explain his bloating. One medical professional reportedly told him it was "the worst I have ever seen". Previous abdominal ultrasounds had failed to identify any underlying cause.
Ultrasound reveals the cause
It was only when he attended an ultrasound appointment to examine his liver that the situation began to unravel. Boyce said: "After the technician scanned my liver, I asked her to take a look at a photo I had taken, showing my extreme bloating before and after. She said 'oh my goodness, that is horrendous, I think I know what that is, lay back down and I'll take a scan'. She identified a possible cause."
While water retention had initially been suspected as the cause, the real culprit was gas. He consulted AI again, inputting the foods he had been consuming, and was astonished to discover they amounted to "a gas factory". His former diet comprised approximately 30 plant-based foods daily, many of which were responsible for his bloating.
Diet changes and current plan
Boyce cited grapes as one particular example, having consumed them regularly, only to discover they were difficult for the body to digest. He said: "When I got home, I used AI - as we do - to do some investigations. I changed my diet and, voilà, my bloating was instantly cured in 24 hours, done and dusted."
He added: "What blew me away was that the diet I was on that caused the bloating was 100% healthy, I couldn't believe it. The diet I was on was tailored to my heart health. It seems hard to believe, but it's true - 24 hours after changing my diet, my bloating disappeared."
Upon realising that his heart-health diet was the root cause, Boyce implemented several adjustments. He spread his '30-a-day' intake across a week rather than a single day, and eliminated wind-inducing foods such as cauliflower, broccoli, wholemeal bread, sprouts and certain cereals. He described it as "finding a balance between heart and gut", and was finally able to manage the condition effectively.
He added: "There must be millions of people across the world who are struggling and don't realise it's a small diet change that can eliminate it." Boyce said he was happy for anyone experiencing similar difficulties to contact him via chris07791@gmail.com.
