Why You Can’t Outrun a Bad Diet: The Metabolic Truth

Why You Can’t Outrun a Bad Diet: The Metabolic Truth

Happy Mindset Monday, everyone! 😎

You’ve probably heard me say this before, but it’s worth repeating – you can’t out-train poor nutrition. A recent study backs this up and provides insights into why focusing solely on “calories in versus calories out” misses the bigger picture.

 

In this study, 14 people—seven pairs of identical twins—tried to “outrun” their diet. Here’s the setup: these sedentary participants did two hours of cardio daily, burning about 1,000 calories each session, for 93 days. They maintained their caloric intake at their normal levels, eating just enough to match their daily needs.

The Results? They lost an average of only 11 pounds over the 93 days—about 0.8 pounds a week. But here’s the interesting part: some participants lost much less weight than researchers expected.

Why? Because as their activity levels rose, their bodies adapted by cutting back on non-exercise energy usage (also known as NEAT—Non-Exercise Activity Thermogenesis). Essentially, the more cardio they did, the fewer calories they burned throughout the day from everyday movements.

Adaptation: The Body’s Natural Response

Our bodies are incredible at adapting to change. Just like your feet would toughen up if you walked barefoot every day, your metabolism adapts to whatever you throw at it. Under-eat consistently, and your metabolism will get more efficient, burning fewer calories and often sacrificing muscle in the process. This makes weight loss even harder over time.

Takeaway: Cardio alone isn’t a weight-loss magic trick. So, if your plan is to “run off” that nightly ice cream habit, spoiler alert: ice cream will likely win.

My Advice? Don’t rely on cardio alone. Instead, prioritize resistance training to build muscle and boost your metabolism. Pair that with a diet that supports your goals, focusing on quality nutrition. Walking is fantastic for mental and physical health, but cardio should be a tool, not the foundation, of your fitness journey. As you approach your goals, then consider adding in a bit of cardio to help you cross the finish line.

Class dismissed! 👨🏼‍🎓💪🏼
