Understanding energy density are essential to managing body weight. The energy density of food explain how many calories are in a specific amount of food. Though salads are consider a low-calorie food, adding a significant amount of dressing to a salad can lead to the salad having a highly amount of calories.
Salad dressings contain a high amount of energy density because they contain a significant amount of calories in a small portion of dressings. Because the energy density of food can differ, it is essential for someone to understand how food affect the calories that a person consume. The macronutrients in food contain different amount of energy for the body.
How Food Calories Affect Your Weight
The macronutrients of protein and carbohydrates contains a moderate amount of energy per gram. Fat contains a higher amount of energy per gram. A small portion of olive oil contains a high number of calories different than a larger portion of lean meat.
Fat contains more energy dense calories than protein or carbohydrates. This means that a person need to eat smaller portion of fat to consume the same amount of calories as lean meat. A person can calculate their Basal Metabolic Rate to determine the amount of calories their body need to function.
The body burns the Basal Metabolic Rate amount of energy while resting to keep the heart and lungs function. However, the Basal Metabolic Rate isnt the total amount of energy that a person needs daily. A person who have a desk job will burn less energy than a person who has a physically demanding job.
Consequently, the person who performs more physical activity will need to consume more calories to maintain the same body weight. Many people does not account for the amount of physical activity that they perform in a day. Consequently, the activity that a person estimates they perform may be higher than the actual amount.
Due to this overestimation, people will consume more calories than there body requires. A person will either create a calorie deficit or surplus in their diet. A calorie deficit will make a person lose weight, while a calorie surplus will make a person gain weight.
Because many factors, such as hormones, sleep, and stress, affect the body, the amount of weight that a person lose or gains may not match the amount of calories that they consume or create a deficit for. Creating a calorie surplus can help a person gain muscle. However, the surplus of calories can lead to the accumulation of fats in the body.
The nutrition label on food products can help a person to understand how many calories is in the food. However, the nutrition label can be difficult to read without knowing the serving size of the food. If a package contain three servings of a product, and a person eats the entire package, the calories will be three times the amount noted on the nutrition label for one serving.
For instance, if one serving of chips contain 150 calories, three servings will contain 450 calories. The ingredient list on the nutrition label can also help a person understand the effect of the food. If sugar is one of the first three ingredients in a product, it will cause a spike in the insulin level in a persons system.
A spike in insulin will make a person feel hungry again soon after eating. Exercise can burn a significant amount of calories. High intensity exercise can help to burn many calories during exercise.
However, it is an inefficient tool for weight loss because a person can consume the calories through eating a single protein bar. Walking is a great form of physical activity to sustain the body. Walking does not put stress on the body and does not make a person feel ravenous for food after exercise.
A person can manage their nutrition without counting the calories that they consume. Using a digital scale can help a person to understand the weight of the food that they eat. This will help them to estimate the portion size that they eat.
Using the plate method of eating can also help a person to consume alot of food with low calories. The plate method involve filling the majority of the plate with vegetables because vegetables have a low amount of energy density. Therefore, a person can eat a high volume of food with a low amount of calories.
By using these technique, a person can control the calories that enter their system from the food that they eat.
