Nutrivore90 FAQ
Answers to your questions about this 3-month habit-centered nutrition challenge.
Q: What is Nutrivore90?
Nutrivore90 is a 3-month habit-centered nutrition challenge that is unlike any other nutrition challenge out there because we focus on sustainable healthy habit formation, so the goal is to improve diet quality while quitting diet mentality. I send you an email every Monday during the challenge packed with tips, tools, encouragement and a new downloadable PDF guide, you actually get 15 downloadable challenge guides in all. The next challenge starts January 5th.
Q: What are the habits I’ll be forming?
The three main habits will you focus on during Nutrivore90 are:
Building balanced meals that include proteins, starches, fruits and veggies, and learning to do so without weighing or measuring your food
Each day, getting 5 servings of veggies and 2 servings of fruit, the most important dietary pattern for long term health and the foundation of nutrient density
And, practicing a non-restrictive diet mindset, learning to include quality-of-life foods without guilt, restriction, or “starting over.”
These may seem like simple goals, but for those of us who have been steeped in diet culture for years or decades, these fundamental healthy eating patterns a game changer. Instead of the old restrict-binge-repeat cycle, you’ll practice habits that make healthy eating automatic, flexible, and actually enjoyable.
Q: Really? There’s no foods to avoid?
That’s right! Nutrivore90 doesn’t rely on cutting foods out—it focuses on what to add in. There are no “bad” foods and no rigid food rules. Instead, you’ll learn how to build a nutrient-dense, health-promoting diet that works with your preferences, values, budget, and lifestyle, and that makes room for quality-of-life foods. It’s a flexible, inclusive approach that ditches the diet mentality so you can finally feel confident, nourished, and free from food guilt.
Q: What if I have dietary restrictions or allergies?
No problem! Nutrivore90 is completely customizable. You’ll learn how to work within your dietary needs while still meeting your nutrient goals.

Q: What kind of time commitment is required?
The challenge is designed to be flexible and sustainable, with a new focus introduced each week.

That said, how deeply you engage and how much time you put in is entirely up to you.
Q: What if I fall behind?
On Nutrivore90, there’s no such thing! This challenge is built around flexibility and self-compassion. The goal is to build consistency, not perfection. You can go at your own pace, take breaks when needed, and pick back up without guilt. Every meal is another opportunity to nourish yourself—no starting over required.
Q: Will I need to buy expensive or hard-to-find foods?
Not at all! In fact, Nutrivore90 celebrates affordable, everyday options like lentils, canned fish, frozen vegetables, oats, and seasonal produce. No superfoods or specialty products required. Just like there are no foods you have to avoid, there are no foods you have to eat.
