Astalwart advocate of healthy living she might be, but Jane Scrivner will have done everything wrong over the festive season.
She will have eaten her fill of mince pies and chocolates, pigged out on Christmas pud and consumed plenty of wine.
But the 35-year-old masseur, health guru and author isn't at all worried.
She will simply ensure she compensates for her over-indulgence by cutting back now that January is under way.
For Jane believes in balance - living healthily but heartily.
Not for her a frugal diet of only brown rice and carrot juice, marathon runs through the country lanes near her home in Warwickshire and an aversion to alcohol.
Yet Jane does lead an extremely healthy and vigorous life. She takes regular exercise, eats wholesomely (including brown rice) and knows not to have one glass of wine too many.
She's learned the art of asking for help when she feels overloaded with work or household chores, and when she feels something isn't quite right in her life, she sits down and plans how to solve the problem.
Her latest book, Detox Your Life, is full of advice on how to bring order to a cluttered and stressful existence.
Jane describes it as "an amalgamation of techniques which are designed to leave you stunningly detoxed and refreshingly raring to go".
With most of us feeling jaded and significantly below par following the millennium celebrations, feeling on top of the world probably seems little more than a pipe dream at the moment.
But, says Jane, it can be done. And it's not only the festive season hangovers her book aims to displace; it sets out a comprehensive programme for keeping us feeling refreshed and full of energy for the rest of the year and beyond.
And the book is not only about detoxing our bodies; it's also geared towards "ridding your mind of all the stresses and strains of everyday living; sorting out all the lingering worries and problems that you hold in your head and doing something about them.
"Detoxing your mind changes negatives to positives and makes you see things differently. Problems disappear and return newly dressed as opportunities or challenges".
Jane explains: "My first book, Detox Yourself, was a healthy eating plan which was part of my job at the time.
"Then I thought, if you've done your inside, why not sort out your outside - all the peripheral things - as well; things like self-esteem and improving your frame of mind."
Although Jane strives to adhere to her own advice, she doesn't always succeed.
While reading the proof of her third tome, The Little Book of Detox, she came across a section about belonging to a gym.
"Have you been a member of a gym for a year and only been once, making the cost of that one swim you had the equivalent of pounds 500?" she read.
It suddenly dawned on Jane that she was guilty of that herself. So she immediately cancelled her gym membership and hired a personal trainer instead.
And she's never looked back. For not only does it work out no more expensive than being an occasional gym user, because the trainer turns up at her home, she is put through her paces whether she likes it or not.
And she's found that the more she works out, the easier and more enjoyable the physical exertion becomes.
Thousands of people will have pledged to shape up, both physically and emotionally, in the New Year, but Jane believes many would have started refurbishing and revitalising their lives even before 1999 was over.
"Somebody told me divorce lawyers were busier than they'd ever been in the run up to the New Year," she says. "That suggests people don't want to go into a new millennium in a bad relationship. …
