Your body has its own internal engine, which keeps everything moving — from breathing, eating, and energy production, to repairing cells, and more. This system tells you how well you are fueling on food and burning calories even at rest. You need a functional system to keep your energy stable, to support organ function, and to help with weight management.
When your body's capacity to burn calories is low, you will likely feel fatigued and be prone to weight gain. A system that is working properly will keep you engaged, motivated, and in check. Learning how to maximize your body's own capacity to burn calories can be life-changing both physically and mentally.
We will discuss how your body metabolizes energy, some of the science behind the processes, and practical information to help your internal engine operate properly.
Before you can comprehend how your body establishes energy equilibrium, you must understand two specific biological processes: catabolism and anabolism.
Basic concepts for energy metabolism include:
Catabolism is the process of breaking down food molecules to release energy, and the resulting energy that your body converts into calories is what you require to perform vital functions.
Anabolism is the utilization of that energy to form and reorganize the structure of tissue, which enables you to grow and recover.
These systems engage with one another and can physically affect how your body utilizes the energy available to you each day. Age, genetics, hormones, and the composition of muscle all influence the rate at which your body burns calories. Muscle tissue burns more calories than fat, even when you are awake and not active — this is the reason weight training can often increase your caloric expenditure, even in a natural way.
Your BMR, or Basal Metabolic Rate, is the number of calories your body utilizes to sustain its most basic functions. If your caloric intake equals your BMR, your weight will stay the same.
However, eating too little can slow your calorie-burning rate over time, leading to fatigue or nutrient loss. On the other hand, too much intake without enough activity will lead to weight gain.
Balancing your calorie intake with activity is essential to maintaining a balance between weight and energy through exercise, good nutrition, and normal physical activity during the day.
You don't have to make drastic changes to your lifestyle to maintain your body's energy system. Simple daily routines can make a huge impact.
Protein elevates the Thermic Effect of Food (TEF)—the amount of energy used by the body to utilize, digest, and absorb nutrients—while also being satiating. Foods such as whole eggs, chicken, beans, and mixed nuts are great satiating foods and promote higher caloric expenditure after meals.
Even mild hydration can slow metabolic function in the body. Specifically, drinking cold water may increase caloric expenditure temporarily, as the body increases caloric expenditure in response to bring the ingested water to body temperature.
Lean muscle mass generates more caloric expenditure even at rest compared to fat mass. Aim to perform resistance (or strength) training at least 3 times a week to increase energy expenditure.
Not getting enough sleep impacts hormones (such as cortisol and insulin), which influence how the body utilizes and stores energy. Aim for a minimum of 7–9 hours of overnight quality sleep to keep the body functioning well.
Eating a balanced breakfast wakes the body after a night’s sleep. By eating a breakfast of protein, complex carbs, and healthy fats, you are giving your body long-lasting nourishment for the morning.
Certain foods will cause you to expend calories more quickly. The following foods can easily be added to your daily eating:
Including these various foods will help keep you energized, able to better control weight, remain alert, and outsmart fatigue throughout the day.
Exercise is considered one of the best ways to increase energy expenditure. Physical activity will have an immediate impact on your heart rate, energy requirement, and oxygen use of the body during physical activity, all working to increase your metabolic rate both during exercise and after.
Hormones are responsible for controlling energy expenditure. The thyroid gland secretes hormones (T3 and T4) that have a direct effect on the efficiency of food being converted to fuel by your body.
If the thyroid is underactive, your energy consumption decelerates; if overactive, it accelerates. Insulin, cortisol, and leptin, among other hormones, impact your energy storage and use, and stress management, blood sugar stabilization, and good sleep can help balance them.
Aging reduces muscle mass, and hormonal changes may slow energy conversion. These can be improved, however, with regular exercise and high protein intake. Staying active, with an emphasis on resistance training, and eating a well-balanced diet will contribute to keeping your energy up and keeping your system efficient.
To keep your body's internal engine running smoothly, you should include the following consistent habits:
Participating in these habits increases the overall quality of being and keeps your system working well.
There are many myths surrounding how we burn energy in our bodies. Let's disprove a few.
Myth 1: Skinny individuals burn calories better.
Not necessarily, being skinny does not burn calories better; muscle mass is usually more important than size alone.
Myth 2: Eating late at night destroys calorie burn.
In the scheme of things, it is not very important in regard to calories as long as your overall calories are appropriate and the meals are of good quality.
Myth 3: You can't alter your metabolism.
Exercise regularly, gain muscle, and eat in balance, and it can make a big difference.
Knowing these facts gives you the power to make smarter lifestyle choices that work for you in the long run.
If you are experiencing unexplained weight gain, fatigue, or other signs indicating an imbalance in your energy system, please speak with a qualified health specialist. They will check your thyroid, hormone levels, and energy system function to determine how to guide you toward greater success with a health improvement plan designed for you.
Your body's energy system is necessary for the function of all body systems - clear thinking, activity, etc. The best way to energize your body is through food, hydration, movement, and sleep.
Consider that your body's energy and burn is not fixed. A few small, habitual changes in your routine will, over weeks, yield drastically better results regarding your energy systems and your poise and well-being overall. Nourish your body, move, and maintain your inner motor blazing for life.
