Let's Talk About Metabolism
If you've ever said, "I think my metabolism is broken," or "I wish I had a faster metabolism," you're definitely not alone. Most people think metabolism is simply how quickly you burn calories, but it's actually much bigger than that. Metabolism is the process your body uses to keep you alive. Every breath you take. Every heartbeat. Every thought. Every step. Every time your body digests food, repairs tissue, regulates hormones, or helps you recover from a workout—your metabolism is at work. Think of metabolism as your body's engine. It's constantly running, even when you're sleeping. The food you eat contains energy in the form of carbohydrates, fats, and proteins. Your body takes those nutrients and converts them into a usable form of energy called ATP. Think of ATP as your body's fuel source. It's what powers everything from blinking your eyes to lifting weights to chasing your kids around the house. Without metabolism, none of those things would happen. So Where Do You Actually Burn Calories? Many women assume most of their calorie burn comes from workouts. Surprisingly, that's not true. Your daily calorie burn is made up of three main parts: 1. Your Resting Metabolic Rate (RMR) This is the energy your body uses just to keep you alive. Even if you stayed in bed all day doing absolutely nothing, your body would still be burning calories to keep your heart beating, lungs breathing, organs functioning, and body temperature regulated. This accounts for roughly 60-75% of all the calories you burn each day. Let that sink in. The biggest calorie-burning activity you do every day is simply being alive. 2. The Thermic Effect of Food (TEF) Your body actually burns calories digesting food. Chewing, breaking food down, absorbing nutrients, and storing them all require energy. This makes up about 10% of your daily calorie burn. In other words, eating food isn't something that "shuts off" your metabolism. Your body has to work to process it. 3. Physical Activity
