Incorporating a "Holistic Nutrition Approach" into the "6 Universal Principles of Influence"

Nargis Akhter | May 2 | 2025

From Robert Cialdini's principles of influence, we can create a powerful framework for guiding healthier, more sustainable dietary choices.

1. Reciprocity - The Power of Giving First

The principle of reciprocity states that people feel psychologically compelled to return favors when something is given to them first.

Research shows that when people receive something beneficial without immediate expectation, they develop trust and are more open to long-term behavioral shifts.  

When someone offers you something valuable—like a free sample of a healthy snack or a friend sharing a nutritious recipe—you naturally feel inclined to "return the favor." This is reciprocity at work. Your brain registers goodwill and makes you more open to trying (or buying) similar things in the future. 

Some more examples:

• If a wellness brand gives you a free guide on gut health, you might later trust their advice more.  

• When a friend cooks you a wholesome meal, you may feel motivated to cook healthy for them too.  

• Key Insight: Be mindful- Does this align with your health goals?

  
  

  2. Commitment & Consistency - "Why Small Steps Lead to Big Changes".

  
  

This principle suggests that once people commit to a small action, they are more likely to align future behaviors with that initial commitment to remain consistent. In holistic nutrition, this translates to encouraging gradual, sustainable changes rather than extreme diets. For instance, asking someone to start with "one extra serving of vegetables per day" (a small commitment) makes it easier for them to later adopt a fully plant-based meal.

Studies in behavioral psychology confirm that micro-habits are more effective than drastic changes because they reduce resistance and reinforce identity ("I’m someone who eats healthy").

Once you commit to a small healthy action—like drinking more water or adding veggies to one meal—your brain seeks to stay consistent with that identity ("I’m someone who cares about health"). This is why tiny, sustainable changes work better than extreme diets.  

How this shapes your behavior:  

• If you start with "Meatless Mondays," you’ll find it easier to eat plant-based food more often later.  

• Writing down your food choices (even loosely) makes you more accountable.  

• Key insight: Start with effortless wins—once they become habit, bigger changes feel natural.  

  
  

3. Social Proof – The Influence of Community & Role Models

People look to others' behaviors to determine their own, especially in uncertain situations.

In nutrition, social proof can be leveraged by highlighting success stories from individuals who improved their health through holistic methods—not just weight loss, but also better digestion, mental clarity, or disease reversal.

Additionally, referencing cultural or ancestral diets (Mediterranean, Ayurvedic, or Indigenous eating patterns) as "time-tested" evidence reinforces credibility.

For example, a wellness brand might highlight how a group of clients lowered cholesterol through whole-food diets, making newcomers more likely to follow suit. Research in public health shows that people are more motivated when they see peers achieving similar goals.  

Humans instinctively look to others to decide what’s "normal" or safe. If everyone at work orders salads, you’re more likely to do the same. If your family eats processed foods daily, breaking that pattern feels harder.  

How this plays out in nutrition:  

• You’re more likely to try a superfood if influencers you admire praise it.  

• Cultural traditions (like Mediterranean or Ayurvedic diets) feel trustworthy because they’ve "worked for generations."  

• Key Insight: Ask yourself "Am I eating this because it’s truly good for me, or just because others are?"  

4. Authority – Trusting Expert Guidance

Why Do You Trust Certain Nutrition Advice?

 Studies show that people are more compliant when advice comes from a trusted, knowledgeable source.  

We defer to experts—but not all "authorities" are equal. A doctor’s advice carries weight, but so does a celebrity endorse a fad diet. Holistic nutrition emphasizes evidence-based, personalized guidance over trends.  

How this affects you:  

• Might follow a diet because a study (or social media) says it’s "the best"—but does it suit YOUR body?  

• Ancestral wisdom (like fermented foods for gut health) often has deep science behind it, even if it’s not trendy.  

• Key Insight: Check credentials. Is this person qualified, or just persuasive?  

5. Liking – Building Trust Through Connection 

We are more influenced by people we like or relate to.

In nutrition, this means practitioners should build rapport by sharing personal struggles (e.g., "I used to crave sugar constantly—here’s how I healed my gut") or aligning with a client’s values (e.g., sustainability, spirituality, or family health).

A plant-based chef might bond with an audience over a shared love of farm-fresh ingredients, making dietary advice feel more relatable. Psychological studies confirm that similarity and warmth increase persuasion, which is why influencer marketing thrives in the wellness space.  

How Food Choices Connect to Relationships

You’re more likely to adopt habits from people you like or relate to. If a friend you admire starts a green smoothie habit, you might too. If a coach shares their own health struggles, their advice feels more genuine.  

• You try a vegan dish because your favorite blogger made it look delicious.  

• You avoid junk food around health-conscious friends but indulge with others who do.  

• Key Insight: Are your food choices sincerely yours, or influenced by who you’re with?  

  
  

6. Scarcity – Creating Urgency for Better Choices

Research in behavioral economics shows that scarcity triggers action, but in wellness, it’s crucial to balance this with ethics—emphasizing nourishment, not fear.  

The fear of missing out (FOMO) drives decisions. "Seasonal superfoods," "last chance to join a cleanse," or "rare supplements" trigger urgency—even if you don’t need them.  

The scarcity principle states that people value things more when they perceive limited availability. In holistic nutrition, this can be framed as:  

• Seasonal eating ("Wild blueberries are only at peak nutrition for a few weeks!").  

• Unique opportunities ("This detox program closes enrollment after 10 spots").  

• Health urgency ("Chronic inflammation now leads to long-term damage—start reversing it today").  

Here are some Useful Suggestions:

1. At the Grocery Store

Reciprocity Trap: Free samples (cheese, dips, desserts) make you feel obligated to buy.  

Smart Move: Politely decline or ask, "Do you have any veggie/healthy samples?"  

Scarcity Trick: "Limited edition!" or "Seasonal favorite!" tags on processed foods.  

Smart Move: Ask: "Would I buy this if it were here every day?" (Mostly, the answer is no.)  

Social Proof Tactic: "Bestseller" labels on sugary cereals or snacks.  

Smart Move: Check ingredients first popular doesn’t mean healthy.  

2. Dining Out or Ordering Food  

Authority Trap: "Our chef recommends…" (often the richest, priciest dish).  

Smart Move: Ask: "What’s the lightest/least processed option?"  

Liking Effect: You mimic your friend’s order ("I’ll have what they’re having!").  

Smart Move: Pause and order what YOUR body craves (e.g., "I’ll start with a salad").  

Commitment Hack: Tell the server, "I’d like extra veggies instead of fries" before others order you’ll stick to it.  

3. Social Gatherings (Parties, Family Dinners)  

Social Proof Pressure: Everyone’s eating cake → you join even if not hungry.  

Smart Move: Bring a healthy dish to share, so you have one "safe" option.  

Reciprocity Guilt: Aunt insists you try her buttery dish.  

Smart Move: Take a small portion ("It’s delicious! Savor it slowly").  

Unity Dynamic: "Our family eats this way"—hard to resist traditions.  

Smart Move: Suggest a new ritual ("Let’s try a fun fruit platter next time!").  

4. Online Food/Wellness Trends  

Scarcity Manipulation: "Only 24 hours to join this miracle detox!"  

Smart Move: Wait 48 hours, if you still want it, research science-backed reviews.  

Authority Illusion: A celebrity promotes a "magic" supplement.  

Smart Move: Check if real nutrition experts (RDs, PhDs) endorse it.  

Liking Bias: Your favorite influencer posts a new "superfood."  

Smart Move: Ask: "Is this affordable/sustainable for me long-term?"  

5. Building Personal Habits  

Commitment Trick: Start with one tiny change:  

"I’ll eat protein with breakfast every day this week."  

Success builds consistency naturally.  

Social Proof Help: Follow accounts that inspire realistic healthy eating (not extremes).  

Reciprocity Boost: Share healthy recipes with friends—they might reciprocate with more promising ideas.  

Key Mindset:  

You don’t need to resist all influence—just redirect it. Example:  

Use scarcity for good: "Berries are in season—let me enjoy them now!"  

Use social proof wisely: Join a meal-prep group to stay motivated.
