Metabolism is:“The chemical processes that occur within a living organism in order to maintain life.” – The Online Dictionary.
“Metabolism is the set of life- sustaining chemical transformations within the cells of organisms. The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes, the conversion of food/fuel to building blocks of proteins, lipids, nucleic acids, carbohydrates and the elimination of nitrogenous wastes…” – Wikipedia.
Still others say – “Metabolism is a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organisms…can be divided in to two categories: Catabolism – the breakdown of molecules to obtain energy. Anabolism – the synthesis of all compounds needed by the cells.” –
If you have a healthy and a good metabolism, you will not gain weight for not watching the calories. You will not gain weight to begin with. This is why most of us had lean bodies as younger people and most of the young don’t need to watch their waistline, I believe.
Though there are those who believe that your metabolism has nothing to do with weight gain or weight loss.
According to the Mayo Clinic:
https://www.mayoclinic.org > metabolism
“It May be tempting to blame metabolism for weight gain.”
“Unfortunately, weight gain is a complicated process. It’s likely a combination of genetic makeup, hormonal control, diet composition and the impact of environment on your lifestyle, including sleep, physical activity and stress.”
“All of these factors result in an imbalance in the energy equation. You gain weight when you eat more calories than you burn – or burn fewer calories than you eat.”
“To lose weight, you need to create an energy deficit by eating fewer calories or increasing the number of calories you burn through physical activity, or both.”
“Increased physical activity will increase your metabolism.”
“Dietary supplements will not help in burning calories or (in) weight loss.
I guess the key? sentence here is – when you increase your physical activity, you increase your metabolism and thereby burn more calories!
To go further into Metabolism: even while you are resting, your body needs energy for all its “hidden” functions, like breathing, circulating blood, adjusting hormone levels, and growing and repairing cells.
The number of calories your body uses to carry out these basic functions is known as your basal metabolic rate – what you might call metabolism.
Several factors determine your individual basal metabolism, including –
• Your body size and composition. People who are larger or have more muscle? burn more calories, even at rest.
• Your sex. Men usually have less body fat and more muscle than do women of the same age and weight, which means men burn more calories.
• Your age. As you get older, the amount of muscle tends to decrease and fat accounts for more of your weight, slowing down calorie burning.
Energy needs of your basal metabolic rate stay fairly consistent and aren’t easily changed.
In addition to your basal metabolic rate, the two other factors that determine how many calories your body burns in a day are:
• Food? processing (thermogenesis)
• Physical activity
Metabolism being the biochemical process that allow people to grow, reproduce, repair damage, and respond to their environment.
The energy released by breaking down what we eat into nutrients, are stored in the body as molecules of adenosine triphosphate or ATP. They are considered to be “the energy currency? of life.”
The energy stored in ATP is the fuel⛽ for anabolic reactions. Catabolism creates the energy that anabolism consumes for synthesizing hormones, enzymes, sugars and other substances for all growth, reproduction, and tissue repair.
So, body weight is a result of catabolism minus anabolism.
To calculate your body weight using BMI or Body Mass Index, (which is an evidence-based method of calculating ideal body weight ranges for age and height) –
1.divide your weight in kilograms (kg) by your height in meter (m)
2.then divide the result by your height again to get your BMI
Although becoming over weight is a result of the body storing excess energy as fat, sometimes hormonal problems or an underlying medical condition may affect metabolism. Therefore, it is advisable to have a medical evaluation done.
Coconut? ? oil and coconut based foods are considered to boost your metabolism, burn fat, protect your brain?, stabilize blood sugar, to name a few health benefits of coconut.
