From Knowing to Doing: Closing the Gap in Plant-Based Living with Timaree Hagenburger

Why Knowing What’s Healthy Isn’t Enough

Most people already know the basics of healthy living: eat more plants, move your body, sleep well, and limit processed foods. And yet, knowing doesn’t always translate into doing.

Why is lasting change so difficult even when the evidence is clear?

In this episode of NHA Today, host Dr. Frank Sabatino sits down with Timaree Hagenburger, MPH, RDN, LD/N, also known as The Nutrition Professor, to explore the critical gap between nutrition knowledge and real-life behavior change, and what actually helps people succeed long term.

With more than two decades of experience in public health nutrition, plant-based education, and community building, Timaree offers practical insights that go far beyond information alone.

The Knowledge–Action Gap

One of the central themes of this conversation is what Timaree calls the knowledge–action gap: the space between understanding what promotes health and being able to live it consistently.

Many people feel inspired after a documentary, lecture, or podcast, but that motivation often fades once real life sets in. Family habits, social pressure, food cravings, and convenience quickly take over.

As Timaree explains, lasting change doesn’t come from willpower alone. It comes from environment, support, repetition, and joy.

Food Cravings, Taste Buds, and Withdrawal

A powerful part of the discussion focuses on food cravings and withdrawal, especially from dairy, sugar, and processed foods.

Timaree and Dr. Sabatino discuss how:

• Certain foods have addictive properties
• Taste buds become muted by excess fat, sugar, and salt
• Flavor perception changes dramatically when whole foods become the norm

As many long-term whole-food, plant-based eaters discover, foods once considered “bland” begin to taste vibrant and satisfying… sometimes surprisingly so.

This process isn’t about deprivation. It’s about recalibration.

Why Pleasure and Variety Matter

One reason dietary changes fail is that they feel restrictive.

Timaree’s work challenges that model. Through her Foodie Bar Way approach, she emphasizes abundance, variety, and enjoyment, showing people how to create meals where everyone at the table can feel satisfied.

Instead of focusing on what’s removed, the focus shifts to what’s possible:

• Multiple options from a single base meal
• Familiar flavors made with whole plant foods
• Creativity replacing rigidity

As Timaree shares, sustainable change must be something people want to return to.

Plant-Based Nutrition in Public Health Settings

The episode also explores Timaree’s work within the WIC (Women, Infants, and Children) program, where she supports families navigating health challenges with limited resources.

She shares moving real-world examples of how plant-based dietary shifts have:

• Improved chronic constipation in children
• Reduced dependence on medications
• Empowered families to see food as a tool for healing

These stories underscore an important truth: plant-based nutrition isn’t just theoretical, it’s deeply practical, even in complex public health environments.

The Power of Community

A recurring theme throughout the conversation is community.

Dr. Sabatino and Timaree both emphasize that community support is one of the most overlooked pillars of health. Without it, even the best intentions can erode over time.

Whether through:

• In-person retreats
• Online groups
• Shared learning spaces

People thrive when they’re not navigating change alone. This philosophy aligns closely with the mission of the National Health Association and its growing focus on creating accessible, supportive spaces for lifelong healthful living.
