Jill Brook has been a nutritionist for over 20 years, and a POTS patient for over 25. She grew up in Wisconsin, earned degrees from Princeton University and UCLA, then worked as a nutritionist and researcher for UCLA and the Pritikin Longevity Center. In 2001 she started her private practice in Pasadena, California, where she worked with adults, college students and sports teams, focusing on cutting edge nutrition for top performance and health, and also on willpower and food psychology…because knowing what to eat doesn’t always make it easier to do it!
Over the years Jill published 3 books, won several awards for outstanding service, and provided nutrition consulting to Disney, Caltech, NBC’s Today Show and others. In 2013, POTS symptoms worsened and forced Jill to move to ever cooler climates and work from home.
As a homebound patient, Jill experimented with nearly every science-backed dietary strategy for autoimmunity, neuropathy, gut and microbiome health, gastroparesis, MCAS, chronic pain management, sleep and more. She also volunteered as a statistician to several POTS researchers (publications below), joined the Boards of Directors of Dysautonomia Support Network and Standing Up to POTS, became Research Advisor to the LDN Research Trust, founded PatientsCount.org, and presented at medical conferences about the connection between diet, gut health, the microbiome, and autoimmunity. After several years of research, trial and error, Jill is back on her feet and feeling good again…so long as she sticks to her wellness routine.
Since 2017 Jill has been Nutrition Consultant to Dysautonomia Clinic and also works for physicians across the US, from California to New York and Florida to Alaska. She has earned a reputation for being able to help people with very complex and challenging situations.

Spark! Weight Loss Coaching Questions
“I wrote this because I wanted to share a simple way to spark more success. Whether you are coaching clients professionally or helping a loved one informally, or even just coaching yourself, a simple change of approach can make all the difference! It’s easy, and makes the weight loss process so much more interesting and enjoyable…and effective!”
“We created this app to help people burn more calories with less effort. Our nutrition practice sees lots of clients who have low metabolisms, and who struggle to lose fat, even when they exercise plenty and eat like monks. How unfair!
Luckily, there are many easy and enjoyable ways to burn more calories, and even a small daily boost adds up to huge results over time. Our clients enjoy having these other options for reaching their weight goals. We hope this helps you, too!”
“At our nutrition practice, poor sleep is the enemy! It causes excess hunger, cravings, blood sugar problems, weight gain, muscle loss, and diminishes will power. How depressing!
Luckily, science has uncovered dozens of smart, easy ways to improve sleep starting tonight. It’s amazing how absolutely everything in life gets better when you are well rested.”
“We created this app because feeling owned by sugar is no way to live!
For years, even after I was a successful nutritionist, I was a prisoner to sugar cravings. The harder I tried to resist, the more I would pine for it, despite knowing better. It made me feel pathetic! I’ve seen many clients enslaved by it too, and the research confirms it’s addictive.
Luckily, science and experience have uncovered dozens of smart strategies that make it easier to break free. I wish I had known these things when I was fighting my addiction, and I hope they help you.
Here’s to breaking free from wanting what’s bad for us!”
1-Minute Weight Wins
“After working with thousands of nutrition clients, it pained us to realize that the nicest, kindest, most selfless people often stayed overweight because they didn’t take enough time for themselves.
Their free time was spent being great parents, spouses, friends or employees, and 40 minutes on the treadmill or cooking homemade food was just never gonna happen!
So we created this app to nudge folks to succeed in their spare moments throughout the day.
These 1-Minute Weight Wins add up quickly over time to help you lose weight, whether or not you ever make it to the gym.”
1-Minute Mood Wins
“When chronic illness struck, it robbed me not only of physical health, but also my cheery disposition. Not acceptable! So my husband and I created this app to nudge me to do all the many easy, quick, painless, healthy things that are proven to help boost mood.
These 1-Minute Wins are surprisingly powerful, and they add up fast. They gave me back control and helped me return to my cheery self again. I still use them daily, because they quickly become habits…plus, you can never feel too happy.
I hope they help you too.”
1-Minute Wellness Wins
“Our nutrition practice sees thousands of clients who know how to take better care of themselves, but never have the time to do it.
So we set out to find a solution. Luckily, scientific research proves there are dozens of easy, quick and painless Wellness Wins that can add up over time to huge benefits. This app can even send you reminder nudges, so you’ve got no excuses now!”
“When I was diagnosed with POTS, I was prescribed 19 different pills! Some had requirements about timing, food, having an empty stomach, or not taking them if I planned to lie down. My whole life became a harried pill-management challenge, and every time I tried to get out and enjoy life a little, my pill routine would need adjusting.
My husband & I created this app so I could have a fun, flexible schedule and take my pills properly. I hope you never have to take a zillion pills, but if you do, I hope this helps.”
“We created TriggerMapper so that allergy sufferers and masto-peeps like me would have an easy and appealing way to track and sort our many triggers, and then be able to easily send this information to others.
Also, as a nutritionist, I know we are much less likely to “cheat” (and then feel miserable!) when we have documented our food triggers plus smarter alternative choices. I hope this helps you stay reaction-free!”
