The first 16 days are hardcore, being oil, alcohol, sugar and grain-free, and should be viewed as sacrosanct. They set the scene for the success of the programme and the metabolic reset it delivers. There are 10 rules to follow, and all the instructions and explanations are found within the book, along with some recipes.

HarperNonFiction has scooped a new book from author and nutritionist to the UK’s fashion and celebrity set Petronella Ravenshear.HBD, which is suitable for all men and women (other than those who are breastfeeding or pregnant) is split into 4 phases. HBDers (Human Being Diet fans and followers) had long been asking for a cookbook to inspire them in the kitchen while they’re following the programme. The first 16 days are oil-free so quite a culinary challenge for those of us who aren’t especially creative in the kitchen. In January 2022 we produced a collaborative e-cookbook – there are some seriously talented cooks and photographers among us – who shared their recipes and photos. When HarperCollins got in touch and said they’d like to do a real, full colour HBD cookbook I leapt at the chance. And it was published, to the great delight of the HBD community in the first week of January this year!
