'If I could give you one bit of advice right now, it would be to take all the energy you're putting into fad diets and put it into becoming the most genuinely healthy version of you. If you've got a plan, you're already halfway there. And now you've got this book, you've got one.'

Davinia Taylor was overweight, depressed and unmotivated. She couldn't walk around the block, let alone go for a run or do an exercise class, and she struggled to keep up with her four young sons. In desperation she turned to biohacking to sort her head out - the unexpected bonus was that she lost nearly three stone and has kept it off for years through a series of health tricks from cold showers, to MCT oil, to ancestral eating.

She spent tens of thousands of pounds on specialists and Harley Street doctors, trying the most cutting-edge therapies available, only to discover that the true secrets of feeling amazing are very easy and affordable. Start with eating for your mental health, and weight loss is an effortless side effect.

Divided into four sections: Mood, Food, Movement and Rest, the book takes a holistic approach to weight loss, reminding you that true health is not just about what you eat. It's Not a Diet concludes with a two-week reset programme to put Davinia's advice into action easily and achievably.
