fu:di was founded by Tom Redwood, a professional chef, and his co-founder Ben, a former mathematics academic at Imperial College London. The origin was personal: Tom had hit 130kg and slid into pre-diabetic territory before Ben pointed him towards a low-carb keto approach. Twelve months later he'd lost 30kg and normalised his blood sugar, but missed properly flavourful food. fu:di exists to give that back.

Every product is built on three rules: reduce carbs, cut the hidden sugar, ditch the seed oils. The mayos swap standard seed oils for cleaner fats. The granolas and crispbreads replace cereal grains with nut and seed bases. Sweetness comes from plant-based sweeteners rather than sucrose or glucose syrup, so you get the foodie experience without the blood sugar spike.

Every brand on our site passes our in-house Keto Shop Curation Process. Our team checks ingredients, macros, and quality before anything earns a spot. fu:di made it in for the standards: chef-led recipes that refuse to compromise on flavour, paired with ingredient calls that actually reflect how keto is meant to be eaten.
