Can You Drink Your Way to a Flatter Stomach?

The Science of L. Gasseri & Organic Greens

What if the secret to a flatter stomach isn’t just about what you eat – but what’s already living inside your gut? I’m not a scientist, but I’ve dug into the research to uncover how your gut bacteria influences where your body stores fat – and, more importantly, what you can do to tip the scales in your favour.

Part 1: Let’s Kill the ‘Magic Juice’ Myth First

Here’s something you deserve to know upfront: most ‘flat tummy teas’ are laxatives in a fancy box. They make you lose water weight, dash to the bathroom, and feel vaguely violated by the whole experience. The weight comes back. The bloating comes back. And you’re left £30 lighter with a lot less dignity.

But here’s where it gets interesting. While the wellness industry has been flogging glorified diuretics, the science of gut microbiology has been quietly doing something remarkable. Researchers have been zeroing in on a specific strain of bacteria — Lactobacillus gasseri — that appears to have a genuinely measurable effect on where the body decides to park its fat stores. Not just ‘general weight,’ but visceral fat. The hard, deep-belly fat wrapped around your organs that no amount of crunches can reach.

“Most flat tummy teas are just laxatives in a fancy box. But science is finally catching up to how our gut bacteria — specifically a strain called Lactobacillus gasseri — actually dictates where our body stores fat.”

That’s what drew me to Super Green Juice by TouchStone Essentials. Not the greens themselves (though they matter, as we’ll get to). It’s that the formula treats the gut like a living ecosystem — a community with rules, dependencies, and consequences — rather than just a cavity to pour nutrients into. I think that shift in philosophy changes everything.

Part 2: The Science — How L. Gasseri Actually ‘Blocks’ Fat

The Bus Stop You’ve Never Heard Of

Fat doesn’t just float through your intestines and quietly disappear if you’re lucky. It has a very specific transit system. When you eat fat, your digestive system breaks it into fatty acids and monoglycerides, which then reassemble into structures called micelles — think of them as tiny, microscopic shuttles. These micelles carry fat molecules to the walls of your small intestine, where they pass through and enter the bloodstream.

That’s the journey fat takes from your plate to your waistline. And it’s precisely at the micelle stage where Lactobacillus gasseri appears to intervene.

“Imagine fat molecules are like passengers trying to board a bus. L. gasseri makes the passengers too big to fit through the door — so they pass through the system instead of being stored.”

I came across a landmark study published in the British Journal of Nutrition (Kadooka et al., 2010), which revealed something fascinating: participants who took L. gasseri SBT2055 for 12 weeks saw a significant reduction in abdominal visceral fat – an average of 4.6% – compared to those who took a placebo. But here’s the catch: once they stopped the supplementation, their fat levels began to creep back up. This wasn’t just a short-term effect; it hinted at an ongoing biological process at work.

What’s Actually Happening in There

So how exactly does L. gasseri work its magic? Research points to multiple, overlapping mechanisms. For starters, it disrupts fat absorption by interfering with micelle formation and bile salt activity in the small intestine, making it harder for your body to soak up dietary fat. But it doesn’t stop there. I’ve learned this probiotic also reprograms lipid metabolism genes in your intestinal cells, essentially dialing down your body’s instinct to absorb and stash away fat. The result? A smarter, more efficient approach to how your body handles what you eat.

A 2013 study in the Journal of Nutritional Biochemistry took this a step further, showing that L. gasseri doesn’t just reduce fat—it actually rewires how your body processes it. The research found that this probiotic influences the expression of genes tied to lipid absorption, particularly through the PPAR-alpha pathways, which regulate fat oxidation. In plain terms? It helps your body burn fat instead of storing it.

The result? More dietary fat simply passes through your digestive tract instead of being absorbed and stashed away as stubborn visceral fat. There’s no hocus-pocus here – just precision bacterial interference at the molecular level, where fat absorption is decided. And unlike fleeting trends, this mechanism isn’t just theoretical; it’s validated by peer-reviewed human trials.

Part 3: Why ‘Organic’ Isn’t Just a Marketing Word Here

The Glyphosate Problem Nobody Talks About

Here’s an uncomfortable truth about most greens powders: they might be sabotaging the probiotics they claim to support. The culprit is glyphosate – the active ingredient in Roundup, the world’s most ubiquitous weedkiller.

Glyphosate doesn’t just target weeds – it attacks your gut bacteria, too. It works by disrupting the shikimate pathway, a critical process bacteria use to produce essential amino acids. In essence, it acts like a broad-spectrum antibiotic for your microbiome. Research published in Current Microbiology (Shehata et al., 2012) revealed that glyphosate selectively wipes out beneficial bacteria – including Lactobacillus strains – while leaving harmful, resilient pathogens largely untouched. So while your supermarket greens powder promises gut health, its hidden contaminants could be doing the exact opposite.

“Putting a premium probiotic into a non-organic greens powder is like releasing fish into a river while someone upstream is pouring bleach. The bacteria don’t stand a chance.”

This is why the organic certification in Super Green Juice is operationally significant, not cosmetically significant. It removes the environmental antagonist before it can do damage.

The Enzyme Bridge: Making Sure L. Gasseri Actually Arrives

Even in a pristine, pesticide-free greens powder, most probiotics face a harsh reality: the acidic gauntlet of your stomach. While L. gasseri is one of the hardier strains, survival isn’t a given – and every bacterium lost means less benefit for you.

This is where the enzyme blend in the formula steps in as a game-changer. Amylase and protease enzymes pre-digest food particles in your upper digestive tract, reducing fermentation and acid buildup in the stomach. The result? A smoother, less hostile passage – paving the way for L. gasseri to reach its destination: your lower intestine, where it works its magic.

Imagine the enzyme blend as a VIP escort service for the bacteria: clearing the path, neutralizing threats, and ensuring the probiotic arrives exactly where it needs to be. No detours, no casualties – just maximum impact.

Part 4: The Comparison — Not All Green Powders Are Equal

Here’s where I want to be transparent about why I’m recommending this particular product rather than any of the other twenty powders lining the supermarket shelves. The table below is my honest assessment – draw your own conclusions.

I’m not a fan of the cloying, overly sweetened taste that plagues so many greens powders – which is why the “no stevia” approach here stands out. Animal studies suggest stevia can alter gut microbiome composition, and while human research is still catching up, it feels counterproductive to include a gut-active sweetener in a formula engineered to nurture a specific bacterial balance. Skipping stevia isn’t just about taste; it’s a deliberate, science-backed choice – one that quietly speaks volumes about the thoughtfulness behind this blend.

Part 5: The 30-Day Citizen Scientist Protocol

Why the Scale Will Lie to You

Visceral fat isn’t like the subcutaneous fat you can pinch – it lurks deep in your abdominal cavity, wrapping around your liver, pancreas, and intestines. Here’s the catch: your scale won’t tell the full story. As you shed visceral fat, you might also be building lean muscle, retaining water, or experiencing digestive shiftsall of which can mask your real progress.

So ditch the scale and trust the tape measure instead. A simple morning waist measurement – taken at your navel, relaxed, and at the same time each day – is the most reliable way to track visceral fat loss. Body weight fluctuates; your waistline doesn’t lie.

My 30-Day Protocol

Here’s exactly what I’m tracking over the next 30 days using one scoop of Super Green Juice every morning on an empty stomach:

1. Morning waist circumference (cm), before eating or drinking
2. Morning energy score (1–10) at 8am — a proxy for overnight metabolic activity
3. Evening bloating score (1–10) at 8pm — lower is better
4. Weekly ‘how do my clothes fit’ qualitative note — subjective but underrated

I’m not changing my diet, adding exercise, or altering any other variables. This isn’t a weight loss programme – I’m calling it a gut ecology experiment. The question I’m asking is simply: does optimising this one input shift the outputs?

I’ll be sharing the results here in full, including if nothing changes. Science only works if we’re honest about null results too.

Ready to Run Your Own Experiment?

If you want to test the science yourself rather than wait for my data, I’ve put together a free Visceral Fat Tracker — a simple spreadsheet that covers all four data points above with built-in trend lines. No sign-up faff, just a practical tool.
