Gabrielle Lichterman

Pioneering expert who teaches individuals, groups and businesses how hormones impact women’s moods, health and behavior


I created Hormonology® as an educational outreach mission that teaches women, girls and those who love them how hormones in their monthly cycles impact their moods, health and behavior

There’s a growing movement to sync your life with your monthly cycle—and it all started with me.

In 2005, I published my groundbreaking book, 28 Days: What Your Cycle Reveals about Your Love Life, Moods and Potential (Adams Media). This was the first book to show women how their rise and fall of reproductive hormones in their monthly cycles (estrogen, testosterone and progesterone) impact their moods, health and behavior every day—and how to make the most of these hormonal influences.

28 Days was widely covered in the media and was touted as “one of the top 10 women’s health books of 2005”.

Soon after the publication of 28 Days, I created Hormonology—an educational outreach mission that teaches women and girls how the hormones in their monthly cycles impact their moods, health and behavior.

I developed a suite of Hormonology tools to share this vital information including my popular Hormone Horoscope apps, Female Forecaster app and free guides for adults, teens and parents, teachers and other caretakers of teens.

I’m continually working on new Hormonology tools. And, an updated and expanded version of 28 Days is due to be published soon.

I offer in-person workshops, one-on-one consultations and keynote speaking services that talk about how hormones impact a woman’s moods, health and behavior and how to capitalize on these hormonal effects.

I’m revolutionizing the way you provide sales and service to women ages 18 to 45

My extensive background as an expert in how hormones impact a woman’s moods and behavior has given me unique insight into the shopping patterns of women between the ages of 18 and 45.

What the sales and service industry doesn’t know, but that studies prove, is that women shift between two distinct shopping phases roughly every two weeks—and this makes them respond in completely opposite ways to sales and service techniques.

Once you determine which shopping phase a woman is in—using easy-to-spot clues—you can give her the sales and service experience that makes her happiest. It’s an approach I call “phase matching”.

Pinpointing her shopping phase has additional benefits: It reveals “insider info” about…

· How much she will spend on products and services
· What she wants from her sales or service experience
· The types of details she wants to know
· What inspires her to close the deal

I’ve been sharing information about how women shop to my Hormonology fans for years. But, it wasn’t until I realized how much better my own shopping experiences would be if sales and service professionals were equipped with this information, that I decided to share it with businesses, too.

I also happen to be well-informed about the retail and service landscape. For more than a decade, I was a consumer trends and personal finance journalist who wrote a weekly column in Woman’s World magazine—the top-selling weekly women’s print publication in the U.S.

The valuable information you receive from my in-person sales training, one-on-one consultation and keynote speaking…

· Describes these two shopping phases
· Gives you easy-to-spot clues to pinpoint the phase your client is in
· Reveals how to make her happiest during her sales and service experience
· Tips for marketing to women in both phases

About Gabrielle

For more than 20 years, I was a health, lifestyle and consumer trends journalist

My expertise in women’s hormones and consumer behavior is borne out of more than 20 years as a health, lifestyle and consumer trends journalist for dozens of major print publications around the globe. Just a few of these include COSMOGirl, Girls’ Life, Glamour, Marie Claire, New York Daily News, Self, Teen People and Woman’s World.


As a health journalist, my articles covered a wide range of important health concerns facing women including anxiety, cancer, dementia, depression, heart disease, lung function, menopause, menstrual issues, osteoarthritis, osteoporosis, perimenopause, sleep problems, type 2 diabetes and weight loss.

I’ve also written articles about reproductive hormones and their impact on mood, brain function, energy, libido and other facets of a woman’s life.

Over the years, I focused my reporting on natural, study-backed remedies, such as dietary and lifestyle changes as well as supplementation of vitamins, minerals and probiotics. I also regularly reported on breakthrough research in the fields of health and medicine.

I’ve had the privilege of interviewing many of the world’s leading experts in a wide range of health fields, among them women’s health and hormone expert Elizabeth Vliet, M.D., gender medicine specialist Marianne Legato, M.D., positive psychology pioneers Mihaly Csikszentmihalyi, Ph.D., Christopher Peterson, Ph.D., and Martin Seligman, Ph.D., microbiologist Charles P. Gerba, Ph.D., chronobiology researcher Michael Smolensky, Ph.D., alternative medicine advocate Deepak Chopra, M.D., and biological anthropologist Helen Fisher, Ph.D.

In addition to writing for a wide array of publications, for more than 10 years, I wrote the weekly “News You Need Now” featured health article for Woman’s World magazine—the leading weekly women’s print publication in the U.S.

I was also the editor of WebMD’s large collection of health newsletters delivered to subscribers.


For more than 10 years, I wrote a weekly column for Woman’s World magazine reporting on consumer trends and personal finance.

My column covered a wide variety of issues that impacted the way readers spend and save money:

By tracking news, published research and new surveys, I kept readers up to date on the latest changes in a wide scope of retail and service industries. These included apparel, automotive, big box stores, cosmetics, department stores, discount retailers, drugstores, entertainment, furniture, groceries, healthcare, home delivery, hotels, off-price retailers, online shopping, pharmaceuticals, rental cars, restaurants, ride-sharing, salons, shoes, spas and warehouse stores.

I guided consumers toward improving many facets of their financial life by helping them find novel ways to save money, navigate new retail and job-seeking technology, improve their credit score, update their résumé, cover letter and job interview techniques, secure sensitive personal information and understand changes in banking, credit cards, fees and taxes.

And, I reported on marketing and advertising tactics, pricing structures and the psychology of shopping to help them better understand their spending and saving decisions.


I’m a native New Yorker who now lives in sunny St. Petersburg, Florida with my wonderful husband of over 20 years, Douglas. When not sharing my knowledge about women’s hormonal effects in talks and consultations or while writing books, you can usually find me taking photographs, baking, playing with my dogs and enjoying St. Petersburg’s glorious beaches at sunset.
