For people suffering with IBS, bloating, or chronic gut issues…
A step-by-step system that combines the clinically-proven FODMAP protocol with gut-brain techniques to calm your symptoms AND your anxiety around eating. No guesswork. No conflicting advice. Just a clear plan for each day.


You’ve been dealing with gut issues for months — maybe years. The bloating after meals. The cramping that comes out of nowhere. The anxiety every time you sit down to eat because you don’t know if this will be the meal that sets things off.
So you’ve done what anyone would do. You Googled it. You tried cutting out gluten. Then dairy. Then both. You bought supplements. You ate more fibre (which somehow made it worse). You tried that diet your friend swore by.
And maybe some of it helped a little, for a while. But nothing stuck. Nothing gave you a clear answer.
It’s not because you lack willpower or discipline. It’s because you’re stuck in a cycle:
That changes today.

👉 Reduce quality of life to levels comparable to heart failure and diabetes. IBS patients consistently score lower on physical, social, and emotional wellbeing measures. (Whitehead et al., Alimentary Pharmacology & Therapeutics, 2002)
👉 Are strongly linked to anxiety and depression. Around 39% of IBS patients experience anxiety symptoms and 29% experience depression — and the gut-brain connection means one keeps fuelling the other. (Zamani et al., Alimentary Pharmacology & Therapeutics, 2019)
👉 Lead to “food avoidance behaviour” that can become nutritionally dangerous. When you cut out food after food without guidance, you risk deficiencies in iron, calcium, B-vitamins, and fibre. (Chuang et al., Nutrition Reviews, 2022)
👉 Cost sufferers over $1,100 per year in IBS-specific medical expenses alone — not counting the missed work, cancelled plans, and mental toll. (Buono et al., Advances in Therapy, 2024)
“A low FODMAP diet is now considered a first-line therapy for IBS symptom management. However, it should be implemented with proper guidance to ensure nutritional adequacy and successful food reintroduction.”
Monash University, Department of Gastroenterology — pioneers of the Low FODMAP Diet“A diet low in FODMAPs effectively reduced functional gastrointestinal symptoms compared to a typical Australian diet, with significantly fewer IBS patients reporting inadequate symptom control.”
Halmos et al., Gastroenterology, 2014This isn’t another generic food list. It’s a complete, day-by-day system built on the same evidence-based FODMAP protocol used in clinical practice — simplified so anyone can follow it at home.
Most people guess wrong about their triggers. Using the FODMAP Master Food List and the Gut Reset Tracker, you’ll systematically identify which foods are causing your bloating, pain, and discomfort — instead of randomly cutting things out and hoping for the best.
With the 7-Day Meal Plan and Store-by-Store Shopping Guides, you won’t spend a single minute wondering what to buy or cook. Every meal is mapped out. Every grocery run is planned. You just follow the steps.
Diet is only half the equation. The vagus nerve links your brain directly to your gut, and when it’s sensitised by stress, anxiety, or trauma, it makes symptoms chronic and more severe. You’ll learn practical techniques to calm your nervous system, interrupt the stress-gut cycle, and stop anxiety from undoing your dietary progress.
“I had gotten to the point where I was just extremely ill all of the time. It’s so nice not to feel that way anymore! I have much better control over my symptoms, plus my waistline shrank!”
“The FODMAP diet has changed my life! I was always depressed and it was affecting my life in general, but now food is no longer the enemy for me! Joe’s resources have helped me tremendously.”
“I’m a Mechanical Engineer. My digestive issues required long bathroom breaks and very uncomfortable bloating. This definitely helped me figure out my triggers and enabled me to eat without fear.”
“The biggest improvement for me is simply not being in pain anymore. After completing this program, I’m no longer in constant pain. I can focus on work and enjoy my free time!”
“Thanks so much. You SAVED MY LIFE (really, I couldn’t go anywhere because I needed the toilet too often, sometimes 6-7 times a day). FEELING BETTER, LOOKING BETTER, HAVING A BETTER LIFE!”

The complete 3-Step Gut Reset System in a guided 10-day challenge format

You’ll work through the complete 3-Step Gut Reset System over 10 days. Because you’ll be immersed in this for 10 consecutive days, these tools will become second nature — not something you read once and forget.
Within the first few days, you’ll understand exactly which food groups are most likely causing your symptoms — and have the tools to confirm it.
This is where most people fail on their own — they know they need to cut certain foods but have no idea what to eat instead. That problem is solved.
Your vagus nerve links your brain directly to your gut. When it’s sensitised by stress, anxiety, or past trauma, it can make gut symptoms chronic and more severe — no matter how clean your diet is. This step tackles the other half of the equation.
You get a full 14-day money-back guarantee.
I’m so confident that the Gut Reset Challenge will help you significantly reduce or even completely eliminate your gut symptoms that I’m going to give you a completely fair deal.
If the challenge doesn’t meet your expectations, email my team at support@dietvsdisease.org. We’ll refund your full investment, no questions asked.
We stand behind this program unconditionally because our client satisfaction rate is exceptionally high. We’re responsive, reliable, and here to help.
There’s nothing to lose. And your gut health to gain.
I know how effective this system is and I don’t want you to miss out.

I’m Joe Leech, a university-qualified dietitian from Australia. I’ve been specialising in gut health since 2011, first in clinical practice, then in private consulting focused on food intolerances, autoimmune conditions, and digestive disorders.
In 2019 I founded Diet vs Disease because I kept seeing the same problem: people suffering for months or years with gut issues, getting nowhere with generic advice from doctors who had — on average — just 11 hours of nutrition training in their entire medical degree.
It’s personal for me too. My Grandad Ralph had ulcerative colitis. He was the most social, fun-loving person I knew, until his condition took that away from him. He spent years bouncing between reactive treatments — antibiotics after every flare — without anyone giving him a real plan. He passed away in 2022 from UC complications. It was so preventable.
That experience drives everything I do. I built this challenge to be the clear, step-by-step system that people like him never had access to.
Since then, our team of 12 specialist dietitians — including multiple Monash University-trained FODMAP experts — has helped over 15,000 clients take control of their gut health. 92% report dramatic symptom improvement within weeks.
