Backed by science, The Imperfect Nutritionist celebrates food first, rather than looking at it as points on a plate. Instead of adopting a one-size-fits-all approach and telling the reader what they can and cannot eat, it acknowledges the complexities and uniqueness of the body and offers a diet that you can tailor to your own individual needs.

Part One outlines seven general principles that Jennifer believes underpins any healthy diet:
- Eat whole
- Be diverse
- Factor in fats
- Include fermented foods
- Reduce refined carbohydrates
- Know your liquids
- Eat mindfully

Part Two consists of a 2-week plan plus 100 recipes of dishes that you actually want to cook and eat, using ingredients available at any supermarket.
