You may have heard that protein is essential for building muscle, repairing tissues, and supporting various functions in your body. But do you know that protein also plays a role in providing energy for your cells? In this article, I will explain how protein can give you energy, and what are the best sources and amounts of protein for your health and fitness goals.
Do Protein Give You Energy?
Protein is one of the three macronutrients that your body needs to function properly, along with carbohydrates and fats. Protein is made up of smaller units called amino acids, which are the building blocks of your muscles, organs, hormones, enzymes, and antibodies.
Protein can also be used as a source of energy when your body does not have enough carbohydrates or fats to burn. However, this is not the most efficient way of using protein, and it can have some negative consequences for your health. Let me tell you more about how protein gives you energy, and when you should or should not rely on it.
How Protein Gives You Energy?
Protein can be converted into glucose, which is the main fuel for your cells, through a process called gluconeogenesis. This happens when your body does not have enough glucose from carbohydrates, or when your glucose levels are too low, such as during fasting, starvation, or intense exercise. Gluconeogenesis can also occur when your body needs more glucose than it can get from carbohydrates, such as during periods of stress, infection, or injury.
Therefore, using protein as a source of energy is not very efficient, and it can put a strain on your liver and kidneys. Moreover, using protein for energy means that you are not using it for its primary functions, such as building and repairing your tissues. This can lead to muscle loss, impaired immune system, and reduced metabolic rate.
When to Use Protein for Energy?
Protein should not be your main source of energy, but rather a backup option when your body does not have enough carbohydrates or fats to use. However, there are some situations when you may need to use protein for energy, such as:
When you are on a low-carbohydrate or ketogenic diet, which limits your intake of glucose from carbohydrates, and forces your body to use fat and protein for energy.
When you are fasting or restricting your calories, it reduces your intake of all macronutrients and forces your body to use its stored glycogen, fat, and protein for energy.
When you are doing endurance or resistance training, it increases your energy expenditure and your protein breakdown and requires more glucose and amino acids to fuel your muscles and prevent muscle loss.
How Much Protein Do You Need?
The amount of protein you need depends on several factors, such as your age, weight, activity level, and health status. The Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight per day for adults.
According to the International Society of Sports Nutrition, the optimal range of protein intake for athletes and active individuals is 1.4 to 2.0 grams per kilogram of body weight per day, depending on the type, intensity, and duration of exercise, and the individual’s goals and preferences.
What Are the Best Sources of Protein?
The best sources of protein are those that are complete, meaning that they contain all nine essential amino acids in adequate amounts, and that are highly digestible and bioavailable. These include:
Animal sources, such as meat, poultry, fish, eggs, and dairy products. These are considered the highest quality sources of protein, as they have a similar amino acid profile to your muscles, and they are easily digested and absorbed by your body.
Plant sources, such as beans, lentils, nuts, seeds, soy products, and whole grains. These are considered lower-quality sources of protein, as they are either incomplete, meaning that they lack one or more essential amino acids, or they have lower digestibility and bioavailability than animal sources.
Benefits of Protein for Your Energy and Health
Protein is not only a source of energy, but also a vital nutrient for your health and well-being. By consuming enough protein from high-quality sources, and by optimizing your protein intake and distribution, you can enjoy the following benefits of protein for your energy and health:
Increased muscle mass and strength, can improve your physical performance, appearance, and confidence.
Enhanced recovery and adaptation, can help you heal faster from wounds, infections, and surgeries, and cope better with stress, inflammation, and oxidative damage.
Improved body composition and metabolism, which can help you lose weight, maintain a healthy weight, and prevent obesity and metabolic syndrome.
Supported immune system and overall health, which can help you fight off infections, allergies, and autoimmune diseases, and prevent or delay the onset of aging-related diseases.
Protein is essential for energy and bodily functions, but should not be the main energy source. Consuming too much or low-quality protein can be harmful. It’s important to get enough high-quality protein and distribute intake for energy and health benefits. Share and comment if helpful.
