Some people can eat a lot of food and not gain any weight, while others can have one bite of cake and put on pounds. This may be due to the differences in metabolism types. Here, we explain what metabolism is, read on.
How Do You Define Metabolism?
The term “metabolism” encompasses all of your body’s chemical processes. Your body requires more calories when your metabolism is high. Some people can eat a lot without gaining weight due to metabolism, while others seem to need less to put on weight and become obese. Metabolic rate refers to how fast your metabolism is. Calorie expenditure is a term used to describe how many calories you burn in a certain period.
To sum up, all the chemical events that take place in living organisms, including digestion and the movement of substances between various cells and the above-described set of reactions within the cells, metabolism can be used. Normal metabolism is thrown off in some disorders, including type II diabetes, metabolic syndrome, and cancer.
Nutrition and the availability of nutrients have a strong influence on metabolism. Cells derive their energy via biochemical or metabolic pathways, which is known as bioenergetics. Metabolism relies on energy generation as one of its critical components. Metabolism can be divided into two categories:
- Catabolism
- Anabolism
Catabolism
Metabolic activities that break down big molecules are called catabolism. Food molecule breakdown and oxidation are two examples of these processes. It is the job of catabolic reactions to provide anabolic processes, which construct molecules, with the energy and components they require.
Depending on their energy, hydrogen, and carbon sources (their basic nutritional groups), microorganisms can be categorized as illustrated in the table below depending on the specific nature of their catabolic reactions. When it comes to hydrogen or electrons, organotrophic organisms employ organic compounds as a source, whereas lithotrophs use inorganic substances.
Anabolism
Catabolism releases energy that is then used to create complex molecules through a process known as anabolism. Compound molecules that compose up biological structures are typically assembled piecemeal from simpler precursors. There are three phases to anabolism.
There are three main steps in the biosynthesis process: first, the creation of simple molecules like amino acids or monosaccharides, then the activation of these reactive forms with ATP energy, and finally, the construction of more complex molecules like proteins, polysaccharides, lipids, and nucleic acids from these simple molecules.
The type of anabolism that occurs in organisms varies depending on where the built-up molecules in their cells come from. Many complex organic chemicals found in cells of autotrophic organisms, such as plants, can be synthesized in their cells from simpler molecules like carbon dioxide and water. For the production of complex compounds, heterotrophs require a supply of more complex chemicals, such as monosaccharides and amino acids.
Types of Metabolic Rates
Metabolic rates can be divided into the following types:
Basal metabolic rate (BMR)
When you’re sleeping or resting deeply your metabolic rate drops. An individual should aim to maintain their metabolism at or below this level at all times to keep their organs working properly and stay warm.
Resting metabolic rate (RMR)
A person’s resting metabolic rate is the bare minimum required to keep them alive and functioning. Around 75% of total calorie expenditure is attributed to it.
Thermic effect of food (TEF)
When you are digesting and processing food, how many calories are being burned? A person’s TEF is typically 10% of their overall energy use.
Non-exercise activity thermogenesis
Other than physical activity, the number of calories you’ll need. Fidgeting, altering posture, standing, and strolling about are all examples of body movement.
Factors That Affect Metabolism
- Age – Your metabolic rate slows down as you age. Muscle tissue loss and adjustments to hormonal and neurological processes are to blame. Children go through times of rapid growth during development when their metabolisms are accelerated to the maximum.
- Muscle mass – Muscle mass is a measure of how much muscle you have on your body. The energy requirements of muscle are higher than those of fat. So, the more muscular tissue you have, the more energy you’ll need to maintain your current level of activity.
- Body size – Bigger people have a higher basal metabolic rate (BMR) due to their larger organs and fluid content.
- Diet – Your diet and what you eat changes metabolism to a great length. How you eat and what you eat all count in determining your metabolism.
- Environmental factors – As a result of the body working harder to maintain a normal temperature when exposed to extreme heat or cold, the basal metabolic rate is elevated.
- Physical activity – Exercising builds muscle and speeds up your metabolism, so you burn more calories even when you’re not working out.
- Other factors include gender, hormonal factors, and genetics.
How To Boost Your Metabolism
Eat more protein
Since it takes more energy to metabolize all the food you consume when you eat, doing so raises your metabolism. Compared to carbs and lipids, protein has the greatest thermic effect and can improve your metabolism by as much as 30%.
Drink more cold water
Drinking cold water boosts metabolic rates in two ways. The first benefit is that it can boost resting metabolism by up to 30% for an hour after consumption. In addition, while your body tries to raise its temperature by drinking cold water, you’ll notice an increase in metabolic rate.
Adequate sleep
One of the reasons that sleep deprivation has been linked to obesity is that it can affect metabolism. Sleep increases leptin, a hunger suppressor, and decreases ghrelin, a hunger hormone.
Build on muscle
Even while you’re not working out, your muscles continue to burn calories. Those who undertook resistance training in addition to aerobic exercise had a higher metabolic rate than those who did neither.
Eat small meals regularly
Keeping your metabolism buzzing by eating smaller quantities more frequently helps your body from falling into starvation mode. Rather than doing the start-stop cycle that is frequent with three substantial meals a day, it promotes your metabolism to burn fuel continuously.
