What is the role of fat metabolism in the exercise? 

Daily exercise is an optimal way of maintaining good health. Fats and carbohydrates are the most abundant energy sources that fuel energy during exercise. Fatty acids are mobilized from the peripheral adipose tissue & transported through the blood for activating muscle tissue that is actively engaged in the workout. During the higher intensity physical activities, triglycerides in the muscular tissues are also hydrolyzed for releasing fatty acids for direct oxidation that fulfills the energy requirements. Trained individuals tend to oxidize more fat & fewer carbs compared to beginners while performing activities of the same intensity. The increased capacity of utilizing energy supplies from body fat contributes to increased endurance. Regular physical exercise done in workout clothes also leads to the reduction of adipose tissue mass & improves metabolism. This reduction of lipid reservoir is associated with other interesting changes in the adipose tissue Fatty acid metabolism. Let’s see the role of fat metabolism in exercise.

What is Fat Metabolism? 

Fat is the important component of your diet that fuels exercise and one of the macronutrients. A gram of the dietary fat is equal to the nine calories & a pound of stored fat can provide up to 3,600 calories of energy. Which is highest compared to all of the nutrients, and also our seemingly unlimited fat storage capacity, makes it the largest energy reservoir. 

Fat metabolism is the biological metabolic process that involves the breaking down of ingested fats in fatty acids & glycerol and further into more simpler compounds with the help of other body cells. The compounds get processed & broken down for producing energy that is later supplied to your body cells. Your natural fat metabolism is controlled by the body’s hormones like insulin, adrenocorticotropic hormone, growth hormone & glucocorticoids. Fat catabolism is inversely proportional to carbohydrate catabolism, & under conditions, like diabetes mellitus, its production further increases for countering the decline in carbohydrate catabolism.

These calories are likely less accessible to high intensity trainers performing a quick, intense session such as sprinting or weight lifting. However, fat is essentially important for longer, slower and low-intensity & most of the endurance exercises, like cycling & walking.

Role of fat metabolism in the exercise 

Fat & carbohydrate are major energy sources that fuel your physical activity. Any of the sources can predominate, it depends on the duration & intensity of your physical activity, your physical conditioning, & your diet consumption on the days that you are working out. Fatty acid oxidation contributes up to 50-60% of the total energy expenditure during your low intensity exercise programs. The strenuous submaximal workout requires up to 65-80% of VO2 max and utilizes lesser fat up to 10-45% of the energy expended. 

Your physical training is accompanied by the metabolic adaptations occurring in your skeletal muscle & adipose tissue that facilitate the greater delivery & oxidation of fats during the exercise done in your workout clothes. Training state plays a great role in increasing the flux of fatty acids via smaller pools of the adipose tissue. Which is further reflected by the smaller, and highly metabolically active adipose tissues in your smaller adipose tissue energy depots. 

The blood concentrations containing fatty acids & ketone bodies are comparatively lower when a trained individual is practicing mainly due to the boosted capacity of skeletal musculature for oxidizing the energy sources. Athletes and trained individuals have a higher capability of oxidizing more fat & less carbohydrate compared to the untrained subjects while they are performing submaximal activities of similar intensity. This elevated capacity to utilizing energy from the fat conserves are crucial muscle & liver glycogen stores that contribute a lot big deal to the increased endurance. 

Other benefits of increased lipid metabolism accompany chronic aerobic workout training that causes a reduction in cardiac risk factors. Workout training also lowers your blood cholesterol levels & triglycerides & increases high- density lipoprotein cholesterol. Nutrition experts do not recommend High-fats because of their association with atherosclerotic heart disorders. Evidence shows that low fat and high carb diets can increase your blood triglycerides while reducing high-density lipoproteins. That is why the diets that are extreme in the composition of fat or carbs should be consumed with athletes who indulge themselves in vigorous activities.

Fat oxidation also helps with body recovery and healing after exercise, & during the rest or low power output periods between your high intensity sessions.

Understanding the Dietary Fat

Everything in our diet is made up of macronutrients carbohydrates, proteins & fats. And micronutrients minerals & vitamins. Which are then converted inside the body into further compounds for providing energy that aids your bodily functions. People tend to cut Dietary fat for so many reasons especially when they are trying to lose weight but this nutrient is essential for optimal health. Stored fat also offers cushioning & insulation to your internal organs. It gets the impact and absorbs it which keeps your sensitive major body organs safe. 

Also protects your nerves, transports certain vitamins A, E, D, & K throughout your body & it is the largest stored energy reservoir available for any activity.

Your stored body fat is not the same as your dietary fat. The body tends to store fat. when you eat more calories than you use, from all the you eat, not just the dietary fats. Your body requires an optimal level of fat for health & athletic activity. However, fat is digested slowly to be converted into any other usable energy. This process takes hours. After the break down, it is transported to your working muscles, and stored in the form of body fat. Athletes must be careful regarding the amount of fat they are taking in their diet. 

Popular low-carbohydrate & high-fat diets like the ketogenic diet & the Paleo diet work on the same premise. Their theory is low carbohydrate intake, twined with higher fat & moderate-high protein intakes, which leads to using body fat as a primary fuel source for exercising. Scientific evidence suggests that too long-term low carb-high fat diets can help in improving metabolic risk factors. And are beneficial for high performance in endurance activities. But this diet type requires weeks for the change to occur in the body.
