I Know What I Should Do, But I Don’t Do It

“Exploring the Psychology Behind Our Struggle to Make Healthier Choices”

You’ve probably been there before: You know exactly what you should do to live a healthier, happier life, whether it’s eating nutritious meals, exercising regularly, or getting enough sleep. But for some reason, you just can’t seem to stick with it. You promise yourself you’ll start tomorrow, but tomorrow turns into next week, and soon, you’re caught in a cycle of knowing what’s right and not doing it.

If this sounds familiar, don’t worry—you’re not alone. Many of us struggle with this disconnect between knowledge and action. But why? Why is it so difficult to follow through on the things we know are good for us?

In this post, we’ll dive into some of the psychological barriers that often hold us back and, more importantly, how you can start breaking through them.


The “Action Gap”: Why Knowing Isn’t Enough

In the world of health and fitness, there’s a well-known phenomenon called the “action gap”—the space between knowing what to do and actually doing it. Here are some common reasons why this gap exists:

  1. Overwhelm and Complexity
  • When it comes to making changes, especially big lifestyle changes, it can feel overwhelming. There are so many options, choices, and plans that sometimes it’s hard to know where to start.
  • When faced with complexity, our brains tend to freeze up. We procrastinate because the task feels too big to tackle all at once.
  1. All-or-Nothing Thinking
  • Many of us fall into the trap of perfectionism: If we can’t do something perfectly, we’d rather not do it at all. For instance, you might think, “If I can’t stick to my diet 100%, there’s no point in trying.”
  • This mindset creates unnecessary pressure, leading to paralysis rather than action.
  1. Emotional Eating and Stress
  • Emotional triggers play a huge role in our eating and exercise habits. When we’re stressed, anxious, or even bored, we might turn to food for comfort, even though we know it’s not the healthiest choice.
  • Similarly, stress and fatigue can make it harder to find the motivation to work out or prepare a healthy meal.
  1. Lack of Immediate Results
  • We live in a world that craves instant gratification, but many health goals take time to see results. When we don’t see immediate benefits from eating better or exercising, it’s easy to lose motivation.
  • Without quick wins, it’s tempting to revert to old habits, thinking, “What’s the point?”
  1. Habits and Automatic Behavior
  • Much of what we do daily is habitual. If you’ve spent years eating certain foods or living a sedentary lifestyle, those habits are ingrained. Changing them takes time and effort.
  • Habits operate on autopilot, and without intentional effort, it’s easy to slip back into what feels comfortable.

Breaking the Cycle: How to Start Doing What You Know You Should

Understanding the barriers is the first step, but how do we break the cycle and start turning knowledge into action? Here are a few strategies that can help you move from intention to consistent behavior:

  1. Simplify Your Approach
  • Instead of trying to overhaul your entire life at once, start small. Pick one or two habits you want to change and focus on them. For example, you might start by drinking more water each day or walking for 10 minutes.
  • Success builds momentum, so as you achieve small wins, you’ll feel more motivated to keep going.
  1. Ditch Perfectionism
  • Forget the idea that you need to do everything perfectly. Progress is far more important than perfection. Missed a workout or indulged in an unhealthy meal? That’s okay. Get back on track with the next choice.
  • Embrace a growth mindset—every step forward, no matter how small, is a success.
  1. Address Emotional Triggers
  • If you find yourself stress-eating or avoiding workouts when you’re anxious, start paying attention to your emotional triggers. Are you eating because you’re hungry or because you’re stressed?
  • Learning healthy coping mechanisms for emotions—like journaling, talking to a friend, or taking a walk—can help you avoid falling back on unhealthy habits.
  1. Focus on Long-Term Rewards
  • Shift your focus from immediate gratification to the long-term benefits of healthy living. Sure, eating a healthy meal or hitting the gym may not bring instant results, but over time, these actions will lead to lasting improvements in your health, energy, and well-being.
  • Keep reminding yourself why you’re making these changes, and celebrate milestones along the way.
  1. Create a Supportive Environment
  • Your surroundings can either help or hinder your progress. Make it easier to make healthy choices by preparing healthy meals in advance, keeping workout gear visible, and reducing temptations like junk food in the house.
  • Surround yourself with people who support your goals—whether that’s friends, family, or a coach who can hold you accountable.

The Power of Self-Compassion

One of the most important (and often overlooked) aspects of making lasting change is self-compassion. Many people believe that being hard on themselves will push them to do better, but the opposite is often true. When we’re kind to ourselves, especially when we slip up, we’re more likely to stay motivated and continue trying.

Instead of beating yourself up when you don’t follow through on your intentions, treat yourself with kindness and understanding. Acknowledge that change is hard, and setbacks are a natural part of the process. When you’re compassionate with yourself, you’re more likely to pick yourself back up and keep going.


Conclusion: Start Small, Stay Consistent

It’s easy to feel frustrated when you know what you should do but find yourself unable to follow through. But by recognizing the psychological barriers and using small, consistent actions to break through them, you can start to close the gap between knowledge and action.

Remember: Healthy living isn’t about doing everything perfectly—it’s about making small, sustainable changes that add up over time. Start with one thing, be kind to yourself along the way, and you’ll find yourself moving closer to the healthy life you envision.

If you’re ready to take the next step but don’t know where to begin, consider simplifying your goals and taking them one step at a time. The most important thing is to start—and keep going.
