Meaning
This quote means that muscle tissue is metabolically active. It’s not just inert weight. It’s like having little calorie-burning engines running 24/7.
Explanation
Here’s the thing most people miss. It’s not a massive number, but it’s significant and it’s constant. We’re talking roughly an extra 50-100 calories burned per day for every 10 pounds of muscle you carry. Now, that might not sound like a lot, but think about it. Over a week, that’s an extra 350-700 calories. Over a month? That’s the equivalent of a whole day’s worth of food for some people, just for existing. It’s the ultimate passive income stream for your metabolism. This is why two people can be the exact same weight, but the one with more muscle will have a much easier time staying lean. Their body is simply working harder for them behind the scenes.

Origin & Factcheck
This wisdom comes straight from Michael Matthews’s 2012 book, Bigger Leaner Stronger, which really helped popularize this concept for a mainstream audience in the United States. While the core science behind it—the concept of Resting Metabolic Rate (RMR) and muscle’s metabolic activity—has been understood in exercise physiology for decades, Matthews deserves credit for packaging it into such a memorable and actionable principle.

Context
In the book, this isn’t just a random factoid. Matthews uses it as a powerful argument against the “cardio-only” approach to weight loss. He frames building muscle not as a vanity project, but as a strategic, long-term investment in a faster metabolism. It’s the rationale for why strength training is non-negotiable, even for people whose primary goal is fat loss.
Usage Examples
You see this principle play out in real life all the time. Think about the person who loses a bunch of weight through pure calorie restriction and endless cardio. They often hit a plateau and then regain the weight easily. Why? Their metabolic rate has dropped. Now, contrast that with someone who incorporates strength training. They build muscle, their resting metabolism gets a boost, and they create a much more resilient, efficient body. This quote is perfect for:
- Clients scared of “getting bulky” – to explain that muscle is their best friend for getting lean.
- Anyone frustrated by a weight loss plateau – to introduce the idea of a “metabolic reset” through strength training.
- People over 40 – to combat the natural loss of muscle mass (sarcopenia) and the metabolic slowdown that comes with it.

Common Questions
Question: How many extra calories does a pound of muscle really burn?
Answer: The estimates vary, but a commonly cited figure is about 5-10 calories per pound of muscle per day. It’s not a huge amount on its own, but the cumulative effect over 20-30 pounds of muscle is what makes the real difference.
Question: Does this mean I can eat whatever I want if I have more muscle?
Answer: I wish! It gives you more metabolic flexibility, a bigger “budget” to work with. But you can’t out-train a consistently bad diet. It’s a helper, not a hall pass.
Question: Is this why men often lose weight faster than women?
Answer: Exactly. Higher testosterone levels generally allow men to build and maintain more muscle mass, which gives them a naturally higher resting metabolic rate from the start.
Question: So, should I stop doing cardio?
Answer: No, not at all. Cardio is fantastic for heart health and burning additional calories. The key takeaway is that you shouldn’t only do cardio. The most effective approach is always a combination of strength training and cardiovascular exercise.
