Energy is delivered to the body through the foods we eat and liquids we drink. Foods contain a lot of stored chemical energy. The Process of Breaking down Food and converting it to Energy in the Body is Called Metabolism. Metabolism is the set of chemical reactions that happen in living organisms to maintain life and It is responsible for converting food into energy, building and repairing tissues, and getting rid of waste products.
From a food to energy process point of view, metabolism can be divided into two main stages:
Digestion
Digestion is the process of breaking down food into smaller molecules that the body can use. It begins in the mouth, where food is chewed and mixed with saliva. Saliva contains enzymes that start to break down carbohydrates.
The food then travels down to the stomach, where it is churned and mixed with gastric juices. Gastric juices contain acids and enzymes that further break down carbohydrates, proteins, and fats.
After about 3 hours, the food is emptied from the stomach into the small intestine. The small intestine is where most of the digestion and absorption of nutrients takes place. The small intestine is about 20 feet long and is lined with tiny finger-like projections called villi. The villi increase the surface area of the small intestine, which helps to absorb nutrients.
The nutrients that are absorbed from the small intestine are carried by the bloodstream to the cells throughout the body. The remaining food waste travels to the large intestine, where water & some minerals are absorbed. The remaining waste is then excreted from the body.
Cell respiration
Cell respiration is very complex process by which cells use the energy from food to create ATP, the body’s main energy molecule. ATP is used to power all of the body’s activities, including movement, thinking, and growth. ATP is your body’s energy currency. There are Many Stages of Generating ATP like glycolysis, krebs cycle etc. but it will be too much technical to explain them in details.
The amount of energy that is produced from food molecules varies depending on the type of food. Fat Has Highest Energy Stored Followed By Protein and Carbohydrates, But Body First Consumes Carbohydrates as Primary Energy Source.
If We Categorized Metabolism as per Energy Expenditure then there are mainly two type of Metabolism:
BMR: Basal metabolic rate (BMR) is the amount of energy your body needs to function at rest. It is the energy used to power your organs, such as your heart, lungs, and brain. So Never Think, You Burn Calories Only When Do Workout!
RMR: Resting metabolic rate (RMR) is the amount of energy your body needs to function after waking up in the morning. It is slightly higher than BMR because it includes the energy used to digest food.
There are no Fix Percentage of BMR and RMR in person because it keeps varying as per age, sex, diet, genetics, daily activity, rest time, stress and hormone levels etc. People with more muscle mass will also have a higher BMR and RMR.
Signs of imbalanced or slow metabolism:
- Weight gain or difficulty losing weight, even if you are eating a healthy diet and exercising.
- Fatigue, even after getting a good night’s sleep.
- Poor immunity, such as getting sick more often than usual.
- Cold hands and feet.
- Hair loss, which can be caused by an underactive or overactive metabolism.
- Brittle nails, which can be a sign of an underactive metabolism.
- Acne, which can be a sign of an overactive metabolism.
- Irregular periods, which can be a sign of an underactive metabolism.
- Insomnia, which can be a sign of an overactive metabolism.
Here are some tips on how to keep your metabolism balanced:
- Eat a nutritious diet: A nutritious diet includes plenty of fruits, vegetables, and whole grains. These foods are high in nutrients and fiber, which can help keep your metabolism running smoothly.
- Get regular exercise: Exercise is another great way to boost your metabolism. When you exercise, your body burns calories and builds muscle mass, both of which can help improve your metabolism.
- Get enough sleep: Getting enough sleep is also important for maintaining a healthy metabolism. When you don’t get enough sleep, your body produces more of the stress hormone cortisol, which can slow down metabolism.
- Manage stress: Stress can also affect your metabolism. Find healthy ways to manage stress, such as exercise, yoga, or meditation.
- Eat regular meals: Eating regular meals helps keep your metabolism running smoothly. Aim to eat 3 meals and 2 snacks per day.
- Drink plenty of water: Water helps keep your metabolism running smoothly. Aim to drink 10-12 glasses of water per day.
- Maintain a healthy weight: Being overweight or obese can slow down your metabolism. Aim to maintain a healthy weight by eating a healthy diet and exercising regularly.
Believe Me, if You Don’t Have Good Health then You Will Never Be Able to Enjoy the Life at Its Full.
That’s Why Health is Wealth &
Metabolism is Health!
