The Whole30 is the official UK guide to the popular 30-day nutrition reset created by Melissa Hartwig Urban and Dallas Hartwig. This full-colour paperback edition helps readers identify how everyday foods affect their energy, mood, digestion, and long-term health. It strips away confusing diet rules in favour of a clear, structured programme. With vivid photography, meal plans, and practical tools, it's designed for real kitchens and busy households wanting sustainable change. The programme began as a simple experiment: remove certain food groups, such as added sugar, alcohol, grains, legumes, and most dairy, for 30 days, then reintroduce them one at a time to see exactly how each affects the body. This edition brings the programme to life with clear guidance and an easy-to-follow layout.
