Yes it is. Proteins and carbs have 4 kcals/gram and fats have 9 kcals/gram.
The nutrients Fat, Sugar, Carbohydrates, and Protein otherwise known as macronutrients. The nutrients we are discussing you eat every day without even realizing it. But the only way to get these nutrients, are by eating healthy. Like everything you eat, having to much of these nutrients can cause Obesity.
Your body NEEDS carbohydrates!! Just like you need protein when you're working out, you need fruits, veggies cause they're healthy, you need dairy products for your bones, etc, your body needs carbohydrates for energy!!
Answer is (A) Carbohydrates.
Carbohydrates. Carbs are converted to sugar in the body, and the sugar is the primary energy source. Carbohydrates are the primary components of wheat, corn, potatoes, and some beans. We grind the wheat into flour and bake the flour into bread, so bread, pasta, cake, and any related foods are loaded with carbohydrates. But too much of anything is bad, and excess carbohydrates can be a cause of obesity. Remember, carbs are metabolized into sugar in the body. So you need a balance of carbohydrates and protein (meat, eggs, milk, cheese) to really be healthy.
If there is a high amount of fat or carbohydrates in a snack, it may give you energy for a bit, but cause you to crash later. It will also be high in calories.
Protein is 1 of 3 macro nutrients utilized through the entire body for power. These macro nutrients consist of protein, carbohydrates and fats. Getting a good nitrogen balance is important for correct muscle growth and repair. Correct protein intake can also be needed for that entire body to correctly mobilize stored fat for power. Whenever you are included with an intense weight instruction regimen, much more muscle tissue then normal is in require of repair. This really is the cause why weightlifters and bodybuilders require much more protein.
No nutrients helps hair grow faster, but lack of nutrients may cause your hair to grow slower. Generally, your hair cells need the same nutrients your normal cells need, plus more protein as hair is covered with keratin, a protein combination.
Protein-energy malnutrition (PEM) is a potentially fatal body-depletion disorder. It is the leading cause of death in children in developing countries.
Carbohydrates (specifically glucose) are the preferred fuel for the human body due to the metabolic pathways used to produce ATP (Adenosine Triphosphate). The body produces ATP by both glycolysis and oxidative phosphorylation and the starting point for this production cycle is glucose. However, both protein and fat can be converted into glucose should carbohydrates be temporarily unavailable. However, in the case of fat, too much oxidation of fat into glucose can cause ketoacidosis.
Not enough protein and food that give you energy :)
Carbohydrates is the main source of energy for the body, secondary is fat and tritary is protein.Carbohydrates also cause you to lose weight which usually occurs while your body is resting, in which it breaks down and attach's to fat and then is used as energy.
Eat a lot of protein, and reduce refined carbohydrates, which cause an insulin spike driving down blood sugar levels.
