How does weight loss work in the body?

We all know that in order to be healthy, we need to be in good shape and maintain a healthy body weight, but there is still a lot of misunderstanding about the fat-loss process. Obviously to lose weight we have to understand how the fat reduction process takes place. One frequent misconception is that fat converts to energy and is burnt off during exercise or when calories are lowered. While this is partly correct, there is a more specific answer for how fat exits the body. So, when you lose weight, what happens to your body fat? Let's see what we can find out!

What exactly is fat?

An overabundance of calories causes fat to form. Calories are your body's fuel supply, providing it with energy. Calories come from the foods you consume and are required for everything your body does.

Composition of fat cells

Fat cells are made up of fat called a triglyceride, which can be solid or liquid. Glycerol and fatty acids can be produced from triglycerides, which can then be utilized in metabolic activities or retained in fat tissue.

Only three types of atoms make up triglyceride molecules: carbon, hydrogen, and oxygen. To lose weight, people's triglycerides must be broken down into building units, a process called oxidation. Lipase, a hormone, starts breaking down stored fat when you eat less and exercise more.

Thru the citric acid cycle and electron transport chain, tissues throughout the body, such as muscle and liver, digest previously stored fat. The ATP created is used all across your body, from your muscles to your organs.

To put it simply, after completing a weight reduction exercise, your body burns extra fat to make fuel, which you subsequently breathe out as carbon dioxide or expel through perspiration, pee, tears, and feces.

Fat is a form of energy

Fat is essentially a kind of stored energy. And your body employs this energy in more ways than you would imagine. When you eat, your digestive system needs the energy to break down and store the food, and when you exercise, your muscles require energy as well. This may include anything from just moving your hand to engaging in strenuous activity. Even while you are resting, your heart needs the energy to pump blood to your lungs, which allows you to breathe, and your brain to think. This is your metabolic rate during rest.

In a recent study, scientists explain the destiny of fat in the human body and refute several widespread misunderstandings using exact calculations.

Where does the fat go?

Fat does not simply turn into energy or heat when you work out but the fat passes through several metabolic processes when you start losing weight. It's employed to power all of your body's movement when you're working out. The body transforms fat into useful energy for your muscles and other tissues throughout the fat-burning process, causing the fat cell to shrink.

When fat is broken down for energy, two byproducts remain water and carbon dioxide. Your body uses up all of the other healthy, energetic chemicals in your fat. The water leftover from your fat is ejected via your skin as sweat or excreted through urine. You breathe CO2 through your lungs. Exercise not only expends the energy stored in your fat, but it also removes the traces left behind. The lungs are an excellent fat-burner because exercise causes you to breathe more.

These same cells can reduce in size as you lose fat, however, their number remains about the same. As a result, a reduction in the size of fat cells is the fundamental cause of changes in body form. This also implies that fat cells stay there after you lose weight, and if you don't make an effort to maintain your weight loss, they can simply expand in size again. According to several types of research, this might be one of the reasons why many people struggle to sustain their weight reduction.

Fat burning and exercise

Diet and exercise are the two most important factors in reducing body weight. these have different effects on different people: some people lose weight, others maintain their weight, and a few even gain a few pounds. In comparison to diet or exercise alone, fat loss is more likely when calorie restriction and a nutrient-dense diet are combined with a good exercise plan. Consider consulting a licensed nutritionist for nutritional advice and a professional personal trainer for exercise training for the best results.

Last word

Most of us don't think about where fat goes when we lose weight. In fact, we're just relieved that the weight has vanished off the scale. When your body begins to burn fat, unfortunately, the fat does not immediately go away. A well-balanced diet with a substantial calorie deficit, paired with regular exercise, is the formula for long-term fat loss.
