"Look at my business card. As you focus on it, you might feel your fingers starting to stick together. Tighter and tighter. The more you try to pull them apart, the more stuck they seem to get."

This playful street hypnosis trick never fails to amaze. Eyes widen, laughter erupts, and people tug at their fingers in disbelief. Then, with a simple snap and, “Your hands are back to normal,” they breathe a sigh of relief. And I always leave them with this thought:

"If your mind can make your fingers stick, imagine what it could unstick in your life."

It’s not just hypnotic banter—it’s a challenge. If a suggestion can do this for fun, what about real, lasting change?

Here’s another example. Recently, I tried this with my fiancée’s son. Bright kid with a curious mind. I guided him into a light trance and suggested, “The number between three and five will disappear.” After bringing him back, I asked him to count his fingers. “One, two, three… five, six,” he said, utterly serious. His face? Comedy gold.

We took it further—he imagined his name was Fred. A few taps to reinforce the suggestion, and when asked his name, he confidently replied, “Fred.” Even when pressed about what was on his birth certificate, his answer didn’t budge. Eventually, I brought him back, and while he remembered laughing at “Fred,” the rest was a blur.

It was all harmless fun, but moments like these highlight the mind's incredible suggestibility. In the right state, it can make fingers stick, numbers vanish, or even alter something as personal as your name.

Which begs the question: If the mind is this flexible, can hypnosis really help with addiction, bad habits, or weight loss?

Let’s explore.

What Happens in Your Brain During Hypnosis?

When people think of hypnosis, they often picture swinging watches, velvet capes, and the phrase, “You are getting sleepy.” Forget that. Real hypnosis isn’t stagecraft—it’s neuroscience in action. It’s not mind control. Think of it as guiding someone into a heightened state of focus and openness to suggestion. It’s a lot like getting lost in a great movie or daydream.

So, what’s happening in your brain?

• The Prefrontal Cortex Activates: This part of the brain, responsible for focus and planning, lights up during hypnosis. Studies, like one from Stanford University, show changes in neural activity that make it easier to concentrate on suggestions. (Read the study.)

  
  

• The Default Mode Network (DMN) Calms Down: The DMN, your internal narrator that fuels overthinking and self-doubt, takes a backseat. This quiets the mental chatter, making you more open to new ideas.

  
  

• The Mind-Body Connection Strengthens: Hypnosis boosts communication between the insula (which processes body awareness) and the prefrontal cortex. This explains why suggestions like “Your fingers are glued” don’t just seem real—your body feels it. (See more research on brain connectivity during hypnosis.)

  
  

By quieting your inner critic and syncing mind and body, hypnosis creates a state where deeper patterns and beliefs can be rewritten.

Beyond Party Tricks: Can Hypnosis Help Break Addictions or Lose Weight?

Sure, making fingers stick or turning someone into “Fred” is entertaining. But can hypnosis help with real challenges like quitting smoking, managing stress, or losing weight?

At its core, behaviors like smoking or emotional eating aren’t just habits—they’re deeply ingrained patterns. Smoking might represent “me time,” while stress-eating may evoke comfort or nostalgia. Hypnosis works by addressing these subconscious stories and rewriting them.

Hypnosis for Addiction

Hypnosis doesn’t lecture you to quit—it reshapes how you view the habit. A drink or cigarette might shift from being pleasurable to unappealing. At the same time, hypnosis highlights the benefits of a healthier, addiction-free life.

Research backs this up. A study published in the Journal of Complementary and Integrative Medicine found that hypnosis can outperform nicotine replacement therapies for motivated individuals. It’s not about forcing change—it’s about updating your mental programming.

Hypnosis for Weight Loss

Think of hypnosis as a trainer for your willpower. You already know what to do, but your subconscious might resist healthy habits. Hypnosis can make those choices feel natural, reducing cravings and emotional eating while boosting your confidence.

Here’s how it helps:

• Boosts motivation: Makes lifestyle changes feel like a choice, not a chore.

• Eases cravings: Rewires triggers so unhealthy urges fade.

• Reduces emotional eating: Helps replace comfort food with healthier coping strategies.

• Builds self-worth: Reinforces that your value isn’t tied to the scale.

  
  

A 2018 meta-analysis found that combining hypnosis with therapy led to greater, longer-lasting weight loss than therapy alone. It’s no magic wand, but it’s a powerful tool.

The Power to Get Unstuck

Your mind is a trickster. It can make your fingers stick together or convince you your name is Fred. But it’s also your greatest ally when it comes to change.

Hypnosis isn’t an instant fix. There’s no “magic button” for life’s challenges. But with the right guide and a willingness to explore, you can rewrite the patterns holding you back.

So, can hypnosis work? Absolutely. Not because it gives you superpowers, but because it reminds you of the power you already have.

If your mind can stick your fingers together with a simple suggestion, imagine what it could unstick in your life. What new story will you start writing today?
