This information has helped me tremendously! I have stopped restricting my diet and have greatly expanded my food choices. My blood sugar levels, blood pressure and sleep schedule have all improved.
I’m going through perimenopause. Eating with nutrition in mind and not calorie restriction helped with my energy levels and the most surprising thing after doing Nutrivore90 was I have less hair falling out.
What is Nutrivore90?
Not a quick fix. Not a crash course. Nutrivore90 is the start of something lasting.
This challenge is different from anything you’ve tried before.
Quick fixes and restrictive diets might promise fast results—but they rarely create lasting change. Nutrivore90 is all about building resilience, not rules. It’s about adding nutrient-dense foods, not cutting things out. It’s about consistency, not perfection.
Over the next 90 days, you’ll build small, powerful habits that support real health—without needing to count, restrict, or obsess. Most people don’t struggle with knowing what to do—they struggle with doing it consistently. And consistency doesn’t come from willpower or food rules—it comes from habits.
That’s why Nutrivore90 eases in gently, prioritizes self-compassion, and focuses on sustainable, science-backed strategies. You’ll build momentum with small, practical goals rooted in the Nutrivore philosophy. You’ll reflect, experiment, celebrate progress, and connect with a community doing the same.
This is a habit-centered challenge designed to help you build a nourishing, flexible way of eating for life—no “reset” required. We’ll lay the groundwork for habits that truly last—and then build from there, step by step, week by week.
For so long, my thoughts were constantly revolving around what I should or shouldn’t eat, and it often felt exhausting and, honestly, depressing. However, Nutrivore90 has helped me focus more on nourishing my body, building healthier habits, and freeing up mental space for other aspects of life. It’s been a truly refreshing shift, and I’m deeply grateful for the clarity and balance it’s brought to my relationship with food. It has changed my life forever!
I can’t praise this challenge enough! It was great receiving these emails every Monday. It actually made me like Mondays!! So much good information and laid out really well. I can tell there’s so much work behind it and it’s amazing you can do it for free. Nutrivore90 is so liberating after so many years of restrictions. I lost 2.5 kg (5.5 lbs) during this challenge without losing muscle strength, weight loss being my goal along side with better health, so I am really happy with that.

Instead of rules, you get tools. Instead of shame, you get strategy. Instead of perfection, you get progress.
I’m so impressed with all the guides! It’s clear Dr. Sarah and the team have put SO MUCH TIME into all of this! The graphic design (as always) is all so good. The information is great. It feels like someone who’s never read the Nutrivore book or watched a single video could join Nutrivore90 and get started. Which is so accessible!
I enjoyed the weekly emails. There was just the right balance of information, inspiration and encouragement. This is such a positive resource that gave me permission to add my own flare without guilt. When I have a day of just enjoying food without giving it a lot of thought, I can look back and see how I’ve still eaten nutritiously overall and felt proud of my accomplishment.
Who Is This For?
Whether you’re just getting started—or starting again—Nutrivore90 meets you where you are.
This challenge works for all levels of experience. You can go all in and layer habits quickly—or take it slow and steady, one change at a time.

This is such a supportive program that is so inclusive of everyone’s dietary likes or dislikes. Dr. Sarah’s genuine caring and supportive way of communicating is a joy. Her enthusiasm is contagious.
I am such a big believer and fan of Nutrivore, and think this challenge is a really great approach! I am so excited for those whom this is their entry to Nutrivore, as I think it’s a well structured journey through the different concepts — you’ll finish with a robust understanding of how to nourish your body with confidence, without fuss, and within your own lifestyle.
Nutrivore90 is an organized challenge to work on small “bites” of the core information needed to make changes while focusing on what to include in your daily eating. I really liked being guided with encouragement to concentrate on one aspect at a time to help with not becoming overwhelmed.

Everything about Nutrivore90 has been amazing. Dr. Sarah’s approach is gradual and accepting… so much so, that you learn to be that way with yourself by example. I’ve gone from being a junk-food junkie to a Nutrivore nerd. No one could be more surprised than me that that happened. I tell people about this all the time, feeding these simple changes in small doses.
