What Every BODY is Saying by former FBI agent Joe Navarro takes readers into the fascinating world of nonverbal communication. Drawing from over two decades of counterintelligence experience, Navarro reveals how our bodies often speak louder than words. This practical guide teaches how to read subtle cues—like a twitch of the foot or a shift in posture—to uncover hidden emotions and intentions.
Who May Benefit from the Book
- Professionals in law enforcement or security aiming to detect deception.
- Businesspeople who want to read clients’ real intentions in meetings.

- Job seekers preparing for interviews and improving body presence.
- Anyone curious about human behavior and nonverbal cues.
Top 3 Key Insights
- The limbic brain drives honest, unconscious body reactions that reveal true feelings.
- The face is often misleading; feet and legs show more genuine emotional states.
- Context is key—reading body language without understanding the situation can lead to wrong conclusions.
4 More Lessons and Takeaways
- Body language clusters matter: A single gesture can mislead, but multiple aligned gestures reveal true meaning.
- Comfort vs. discomfort: Navarro classifies behaviors into signs of comfort and discomfort. This simple framework helps spot hidden tension.
- Deception often causes delay: Liars take a moment longer to respond as they create the story instead of recalling facts.

The Book Summary in 1 Minute
What Every BODY is Saying explains how our body communicates feelings through unconscious physical signals. Former FBI agent Joe Navarro shows that our limbic brain reacts faster than we can control, revealing emotions through posture, gestures, and especially the legs and feet. Instead of focusing on facial expressions, Navarro suggests watching for clusters of behaviors, shifts in body posture, and foot movements. These give away real thoughts, especially during stress or deception. He emphasizes the need for context and establishing a baseline before drawing conclusions. Whether you’re in law enforcement, business, or daily life, these lessons help improve observation, empathy, and communication.
The Book Summary in 10 Minutes
Understanding the Language of the Body
Body language is the most honest form of communication. Joe Navarro explains that most people unknowingly express their feelings through gestures, posture, and other nonverbal cues. By watching these signals, you can better understand someone’s emotional state.
The Role of the Limbic Brain
Our limbic system—the oldest part of the brain—controls automatic reactions. This includes how we freeze, flee, or fight when under threat. These responses are involuntary and reliable.
Limbic Reactions Explained
Freeze: When someone suddenly goes quiet or still, it may indicate fear or high stress.
Flight: Turning the body away, stepping back, or pointing the feet toward an exit are signs of discomfort.
Fight: Signs include clenching fists, narrowing eyes, or tightening the jaw. It signals readiness to respond to a threat.
These behaviors often happen before the person is even aware of their emotions.
Feet and Legs: The Honest Communicators
People can control their face and words, but rarely their feet. That’s why Navarro emphasizes watching lower-body cues.
What to Look For
| Signal | Possible Meaning |
|---|---|
| Feet pointing to the exit | Wanting to leave or disengaged |
| Jiggling or bouncing knees | Anxiety, impatience, or nervous energy |
| Crossed legs (firmly) | Closed off or defensive |
| Legs stretched out, relaxed | Comfortable and confident |
Navarro suggests starting any analysis from the ground up. The lower body often reveals the truth.
The Face Can Be a Mask
Most people focus too much on the face. Yet it’s the easiest to control and the most misleading. Smiles can be fake. Nods can be forced. People train themselves to hide emotions through facial expressions.
Instead, Navarro recommends noting facial microexpressions and comparing them with the rest of the body. If the face shows happiness, but the arms and feet are tense, something may be off.
Clusters and Context Matter
One gesture alone means little. It’s the combination of several cues that tells the full story. For example, a person might scratch their nose. That doesn’t always mean lying. But if they also shift their feet, avoid eye contact, and lean away, the behavior suggests discomfort or deception.
The Power of Clusters
- Look for at least 3 consistent signs before judging.
- Consider cultural norms, personality, and situation.
- Never assume from one gesture alone.
Comfort and Discomfort Indicators
Navarro classifies body language into two main categories: signs of comfort and signs of discomfort.
Signs of Comfort
- Open posture
- Head tilted slightly
- Relaxed arms and legs
- Genuine smiling (with eye involvement)
Signs of Discomfort
- Touching the neck or face
- Crossing arms or legs tightly
- Shifting weight from foot to foot
- Pursed lips or jaw tension
Understanding this contrast makes it easier to read people honestly.
Deception and Delay
People telling the truth usually speak fluently. Liars tend to pause or delay their responses. They may also distance themselves physically, blink more, or fidget.
Signs of Possible Deception
- Inconsistent gestures and words
- Delayed responses
- Increased grooming behaviors (fixing clothes, touching hair)
- Limited use of hand gestures
Still, Navarro warns not to assume lying. Deception cues should always be backed by a pattern.
Baseline Behavior Is Key
Everyone has a natural way of acting. Before interpreting their gestures, you must observe how they behave when relaxed. Only then can you spot meaningful changes.
For example, if someone always shakes their leg, it might not signal nerves unless they stop shaking during a stressful question.
How to Establish a Baseline
- Watch them in a calm setting
- Take mental notes of speech pace, eye movement, and posture
- Compare future behaviors against this baseline
Situational Awareness
Body language must be interpreted in context. A person folding arms in a cold room might just be cold—not defensive. Always link the gestures to the environment and emotional triggers.
Example: In a job interview, someone shifting in their seat might feel nervous. If they also touch their face and avoid eye contact, discomfort is likely.
Building Observational Skills
To become better at reading people, Navarro suggests daily practice.
- Observe strangers in public.
- Focus on one part of the body at a time.
- Don’t jump to conclusions—just collect data.
Over time, your ability to notice subtle shifts will grow.
Applications in Real Life
This skill benefits everyone. From parents to salespeople, reading body language builds trust and insight.
Common Use Cases
- Spotting dishonesty in negotiations
- Sensing emotional distress in friends
- Gauging comfort during dates or interviews
- Understanding team dynamics in meetings
