PROVEN BREAD A DELIVERED TO YOUR DOOR

PROVEN BREAD — THE 12-WEEK RESET
Bread that changes how you eat — and how you feel.

Proven Bread is not just bread. It is a 12-week reset programme designed to transform the way you eat, understand, and respond to bread. Developed by Dr Vanessa Kimbell through her doctoral research, this is the healthiest bread you will ever eat — delivered fresh to your door.

Baked to the BALM Protocol, each loaf contains over 30 diverse plant-based ingredients: regeneratively grown grains, legumes, seeds, and botanicals. The flour is hand-blended, stone-milled, and never synthetically fortified. Slow fermentation over 18 hours with a live sourdough culture improves digestibility, nutrient bioavailability, and flavour. Every slice contains 6g of fibre, high polyphenols, and a spectrum of micronutrients — supporting gut health, stabilising blood sugar, and promoting satiety. This is functional food, often referred to as a clinical bread.

But the bread is only part of the story. The 12-week Proven Programme guides you through eating bread in a way that nourishes your gut, connects you to the soil and your community, and changes the way you experience this staple food. You will learn:

  • How to eat bread for better health

  • How to pair bread with other foods for maximum benefit

  • How to notice and respond to how your body feels after eating it

At the end of the 12 weeks, you will  continue receiving Proven Bread as a bread-only subscription — but with the knowledge and confidence to enjoy it as part of a truly nourishing diet.
