Even More Of The People We’ve Helped...

"Now I know what’s triggering my bloating, I know how to avoid it, so I can feel comfortable that I can go out for a meal with friends and I know what things to choose from the menu"- Jenny

"My mantra is if not now, when? Do it, you have to. I mean, you health is more important than anything else because if your gut is unhealthy, your brain’s unhealthy too."- Denise

"Movement is much better now. I don’t have the same bloating, gassiness, digestive rumbling around all the time in my stomach, and I just feel a lot better, I feel lighter. I did lose weight on the program too. I lost 18 pounds."- Pam

“Now I feel like I could run a marathon every day. I have energy, my stomach has flattened out. I’ve had three C-sections, so there’s always going to be that little bit of a pooch. That’s even flattened out. Like it’s just seriously life-changing for me"- Luann

"Now I have a better understanding where I can look at the situation more critically and say, well, I think it was this or I think it was because I had this."- Lissa

“I feel good. I understand what triggers my symptoms.” -Sandra

“I’m not really thinking about my gut anymore and that it doesn’t feel good” -Matt

”The program made a huge difference in me” -Roslyn

”I’m so much happier, I can fit into my clothes and I have my confidence back” - Valerie

Life With Gut Issues Can Be Miserable!
Does any of the following sound familiar?
  • You’re stuck in a cycle of crippling ‘stomach clutching’ pain and frustration… some days it feels worse than labor
  • Gut problems affect every aspect of your life. You can’t do the things you enjoy, spend meaningful time with the people you love, or even work — without pain, anxiety, and shame
  • Every time you get sick or have a ‘flare-up’ it seems to get worse. Now you’re terrified of something serious happening
  • You’re either chronically backed up or going 6 times a day… either way, all you want is some normality
  • ​Constant fatigue and exhaustion sap the joy out of life. You want the ‘old you’ back
  • Sports, dining out, long walks… these are all things you can’t enjoy anymore
  • Weight has slowly crept up on you... and you're self conscious of your swollen bloated belly. None of your favorite clothes fit anymore
If you can relate to any of these…

Or if you've struggled in any other way with gut-related issues...

I want you to know something important…

It’s not your fault.
Why ‘Balancing’ Your Gut Is So Difficult
Many people feel lost and defeated when they try to soothe their tummy troubles…

Including restrictive diets and expensive trips to the doctors…

But nothing seems to work in the long term.

The truth is, there’s no one-size-fits-all approach.

Every single person's body, triggers, and gut is 100% unique…

Which means that almost any advice you get simply won't work for you.

But with the right support and guidance...

It really is possible to soothe your painful symptoms, fix your gut, and enjoy a fun life…

Packed full of energy, stamina, and drive...

While hitting your weight loss goals...

All without following a confusing or restrictive diet.
From my experience, you likely fall into one of two categories:
Camp # 1 : Your Tummy Troubles Are Annoying
Perhaps your tummy hurts a little…

And the bloating is embarrassing.

Somethings not right with your ‘movements’.

Maybe they happen too often…

Or not often enough.

Either way, your confidence is knocked and you’re not sure what to do next.

Camp # 2 : Your Tummy Troubles Are AGONY
Most of your day is spent in agony…

Either bent over in pain or clutching at your stomach…

While frantically scrambling for the nearest bathroom.

You bloat so much that it hurts…

Not to mention that weight seems to have crept up out of nowhere.

You’ve tried everything to feel better, but nothing works…

You’re not sure how much longer you can keep up with this.

Frankly, life is miserable right now.

No matter which camp you fall into…

We can help you break free from the shackles…

Just Like These People Who Healed Their Gut With Our Help

”I feel like I’ve made a lot of progress through this program” - Rachel

”I’ve got more energy, I don’t have the bloating and I’ve lost 13-14 lbs” -Chris

"Do it now. It gets you the results and it will change your life". - Stephany

"It's one less thing to worry about now." - Tara

"I'm not curled up on the couch in pain anymore. My life is back to normal!" - Pamela

"I lost 18 lbs, but that was just a side effect of what I truly gained, which is the mental clarity and knowledge that I can manage my IBS"- Charleen

"He’s able to go to a meeting and actually sit through it without having to take a break. And he’s also able to go out to eat without fear or worry that he’ll pay for it the next day."- Chris

"I've lost over 60 lbs. I feel great and I don't take blood pressure medications anymore" -Julie

”You have to give it a try, it’s worth it. It’s invaluable information” -Joan

”By eating the proper foods for me, I don’t have any problem at all” -Linda

”It’s just wild actually having a normal functioning body for once” -Lauryn

”It feels like a huge weight lifted off my shoulders, knowing what I can and can’t eat” -Amber

Why Nothing You Try Seems To Work...
Strict Elimination Diets
Elimination diets play a role…

But they aren’t a “forever” thing.

After all, they can mean missing out on your favorite foods…

And food should be something you ENJOY.

You need to do elimination diets the right way for them to work.

Medication can make a world of difference for some people.

But for most?

It’s a band-aid solution that doesn’t fix the route cause…

Meaning the problem keeps coming back.
I often speak with people who’ve had some success in healing their own gut…

But the moment they encounter stress…

Their symptoms come crashing back with vengeance…

Without warning or mercy.

It can feel like nothing will ever work.

Until now...

Sitting On The Fence? There Are 3 Paths You Can Take
Path 1 — You ignore us...
When you choose this path, you’re saying that you accept the way you feel right now.

You understand that you’re never going to feel confidence and happiness…

You’ll live with constant pain, anxiety, and fear...

Things could get worse…

And you could spiral downwards…

Not to mention that more and more weight could begin to pile on…

Because inflamed, angry tummies make weight loss feel virtually impossible.

When you choose this path you’re giving up — even though you and your family deserve better.
Path 2 — You take on board what you’ve read here, but choose to fix your gut alone
I respect you for trying.

You’re clearly serious about fixing your problems.

But just know this, when you choose this option you’re “guessing”...

Instead of using a scientific system that’s already helped 2,000+ people soothe their pain, fix their embarrassing symptoms, and live a life free from chronic pain.

You’ve likely tried to fix things before, so honestly, what makes you think this time will work?

After all, if you could do this alone, wouldn’t you have fixed your stomach problems by now?

The truth is, in a year or two, you might be back here looking for help…

Having wasted a tonne of time, money, and energy…

While living a painful, anxious, embarrassing life.

You could end up gaining weight and feeling worse.

Because without our scientifically-backed guidance, education, and support — healing your gut can feel impossible.

I think this is the wrong choice, and I wouldn’t be doing my job if I didn’t say so…

But I respect your decision.

Path 3You say, “YES! I DESERVE HELP!”
You realize you’re 100% worth it and join us today.

You deserve to live a life free from pain and embarrassment...

To reclaim your energy, mood, and happiness.

You make simple lifestyle and diet changes that transform your belly, body, and mind — forever.

You’ll feel lighter and brighter, bursting with energy…

Going to social events and living an active life…

Without worrying about where the nearest restroom is.

You lose weight…

Clothes fit better…

And when you dine out, you can’t help but smile as you confidently know EXACTLY what foods to order…

Allowing you to have more fun and make more memories with the people you care about.

Your partner, friends, and family notice the difference in your mood and energy…

It’s almost infectious.

You sleep better at night because the pain in your stomach and the tension in your neck and shoulders has melted away…
