Where We Create, Tweak and Enhance Keto and Low Carb Breads and Baked Goods
🍞 Three Ingredients, 10.9g Fibre a Slice
This keto bread fits beautifully into a flexible keto or low-carb lifestyle. While it’s naturally gluten-free, it is not suitable for celiac disease due to potential cross-contamination during ingredient processing.

Why It’s Valuable
The Power of Your Daily Slice
Eating a slice of this bread offers three carefully selected ingredients working together. Every body is different, and this isn’t medical advice, but here’s what each one may contribute.
Golden Flax Seeds
Deliver omega-3 fatty acids and lignans, which may support a healthy inflammatory response, hormone balance, and prolonged satiety.
Psyllium Husks
Provide gentle, soluble fibre that may nourish your gut microbiome, soothe digestion, and support regular, healthy elimination — a genuine cornerstone of overall wellness, and one that doesn’t depend on anything surviving the bake.
Living Biome Boss™ Sourdough Starter
Brought to life with coconut and almond flour, the living starter contains lactobacillus and wild yeasts before baking. While baking reduces live microorganisms, the fermentation process leaves behind organic acids and compounds that remain in the finished loaf and may support digestive comfort, alongside contributing that authentic sourdough tang.
The Science
Why This Works: Fibre, Fermentation & Flavour Together
Together, these three ingredients create a genuinely fibre-rich, well-fermented loaf. The soluble fibre from psyllium and the fibre and lignans from flax provide substantial bulk that may support satiety and regularity on their own, independent of the starter.
The living starter’s role is primarily about flavour and dough behaviour before baking: it contributes authentic sourdough tang, and its fermentation process may help pre-digest some proteins and carbohydrates, potentially making them easier to process. Because baking reduces live microorganisms, the finished loaf’s gut-related benefits come mainly from its fibre content and fermentation by-products, not from live bacteria arriving in your gut.
A Daily Ritual
A Morning Ritual for Wellness
Many people enjoy their daily slice in the morning, when the body is ready to reset and refuel. Thanks to its substantial fibre content, this nourishing ritual may help support steadier blood sugar, ease cravings, and support a calm digestive system. Over time, the fibre may help encourage a natural, healthy rhythm of daily bowel movements and support sustained energy.
Shari’s Story
My Personal Experience
For me, being able to have a consistent, healthy bowel movement every day by simply eating one slice of this bread has been transformative on so many levels. Regular elimination may help reduce bloating and discomfort, support nutrient absorption, and support a healthy gut — all of which have contributed to me feeling lighter, more energized, and balanced both physically and mentally.

Let’s Bake
Four Ways to Bake Your Keto Bread
One Practice Loaf
It may take one practice loaf to find the exact baking time that works best for your oven, since results can vary depending on the brand, age, and whether you’re using a convection oven, small countertop convection, or air fryer. Breads made with flax, psyllium, and nut flours naturally bake differently than grain breads — they hold more moisture and can sometimes feel slightly soft or “gummy” in the centre even when fully cooked. This is completely normal for high-fibre, low-carb recipes.
Keep a simple record of your oven temperature, bake time, and results for each loaf until you find your magic combination. Once you do, every loaf will bake beautifully and reliably. If your loaf ever feels a bit too moist inside, simply wrap it in foil and return it to the oven for 15 minutes at 325°F to help it finish setting. Always check for doneness with an internal temperature of 200–205°F.
Method 1: Convection in Regular Oven (Recommended)
Temperature: 325°F convection
Baking Time: 75–80 minutes
Cooling: Turn off oven and let bread rest inside for 20 to 30 minutes before removing
Why it works: The slightly lower temperature and longer bake allow the interior to cook through slowly, preventing the dense or gummy centre that’s common in flax and psyllium breads. The shorter rest time keeps the crust from hardening while the middle finishes setting.
Method 2: Small Convection Oven
Temperature: 325°F
Baking Time: 60–65 minutes
Cooling: Turn off oven and let bread rest inside for 15–20 minutes
Shape note: Form a slightly smaller loaf to fit the pan and ensure even baking
Why it works: Compact convection ovens heat more intensely, so lowering the temperature gives a gentler bake that allows the centre to dry evenly without over-browning the top.
Method 3: Traditional Oven (No Convection)
Score bread: to help prevent cracking and allow steam to escape
Temperature: 340°F
Baking Time: 75–80 minutes
Cooling: Turn off oven and let bread rest inside for 15–20 minutes
Why it works: The slightly higher temperature compensates for reduced air circulation. Scoring releases trapped steam, helping the interior firm up while keeping the crust tender.
Method 4: Ninja Air Fryer or Compact Air Oven
Temperature: 325°F
Shape: form a smaller, flatter loaf to allow hot air to circulate evenly
Check frequently: begin checking at 40 minutes; the top should be golden brown and the loaf should feel firm to the touch
Cooling: cool on a wire rack for 30–45 minutes before slicing
Why it works: Air fryers heat from all sides in a confined space, so a lower temperature prevents the crust from darkening before the centre sets.
Critical Tips
Critical Tips for Success
Use freshly ground golden flax for lighter colour, superior nutrition, and no bitterness. Already-ground flax has oxidized and will make your final loaf darker with a bitter taste.
Water ratios matter: if using already-ground golden flax and psyllium, you’ll need 1¾ to 2 cups of hot water. Always start with 1¾ cups.
Don’t add starter to hot dough — wait until cooled, or you’ll kill the beneficial bacteria before it even has a chance to ferment the dough.
Perfect consistency: let the dough rest for 30 minutes. This stiffens the dough so you can shape it and it will hold on the baking sheet. You want the dough to be moist but not too wet, or it will flatten on the baking sheet and deflate once baked — or too dry, as it will crack.
Let it cool completely — hot bread will crumble. Patience creates perfect slices.

By the Numbers
Adding to Your Daily Fibre
A single slice of this bread containing 10.9 grams of fibre provides a substantial portion of your daily fibre needs.
For women, who need about 25 grams of fibre per day, one slice delivers approximately 44% of the daily recommendation — nearly half of what’s needed.
For men, who require about 38 grams daily, one slice provides roughly 29%, or about one-third of their daily fibre intake.
This is quite impressive compared to regular bread, which typically contains only 1–3 grams of fibre per slice, making this a significantly more fibre-rich option that can help you reach your daily fibre goals more easily.
Keeping It Fresh
How to Store Your Keto Bread
Room Temperature Storage
Store in an airtight container for up to 2 days at room temperature. Best for immediate consumption; keeps crust slightly soft.
Refrigerator Storage
Wrap tightly in plastic wrap or store in an airtight container for up to 5 days. Reheat slices in a toaster or oven for best texture.
Freezer Storage
Slice the bread before freezing for easy portioning. Wrap individual slices in parchment paper, then place in a freezer bag for up to 3 months. Thaw at room temperature for 15 minutes or toast directly from frozen.
Pro Tip: Pre-slice and freeze the entire loaf so you can grab single servings for quick breakfasts or sandwiches.

Allergy Warning
This bread contains tree nuts (coconut, almond) and seeds (flax, psyllium). If you have allergies to nuts or seeds, do not consume this product. Always check ingredient labels carefully, as manufacturing facilities may process other allergens.
Ingredient Considerations
Research suggests that flax seeds may help support healthy blood pressure levels in some individuals. If you already have low blood pressure or are taking blood pressure medication, consuming flax regularly could potentially cause dizziness or other symptoms. Psyllium husk may interact with certain medications and can cause digestive discomfort if not consumed with adequate water. Always discuss dietary changes with your healthcare provider, especially if you have existing health conditions, take medications, or have known food allergies or sensitivities.
