However, consuming adequate protein at or above the recommended amount is necessary to maintain lean body mass. How many calories you consume and what percent of your calories come from each macronutrient can be manipulated to meet your individual needs and goals. This is a much-discussed and debated issue, and the current understanding is that there is no one-size-fits-all recommendation. These recommendations are broad and meant to cover the needs of many different people with different dietary situations. The Institute of Medicine recommends an acceptable macronutrient distribution range for carbohydrates (45-65% of energy), protein (10-35% of energy), and fat (20-35% of energy limit saturated and trans fats). Alcohol contains 7.1 calories per gram (7.1 kcal/gm), and the liquid calories can add up fast! How many calories do I need? However, since alcohol does contain calories, it is best to include it here. Even though protein can provide energy, its primary purpose is to support muscle growth, maintenance, and repair.Īlcohol: Alcohol by itself isn't considered part of the nutritional food groups. What makes it unique is that it contains nitrogen. Protein: Protein is an energy-yielding nutrient like fat and carbohydrates, and it provides about 4 kcals per gram. Therefore, foods with a much higher fat content provide more calories per gram than foods with a high carbohydrate content. Because of these hydrogens, fat has more than twice the calories of carbohydrates. Chemically, fat is made of carbon, oxygen, and hydrogen but has twice as many hydrogen atoms as carbohydrates. For every gram of carbohydrates consumed, 4 kcals of energy become available.įats: Foods such as oils and butter are the most common fat sources, also referred to as lipids. Chemically, carbohydrates are composed of the elements carbon, oxygen, and hydrogen. The nutrients that contribute to caloric intake include:Ĭarbohydrates: Sugars, starches, and non-energy-yielding nutrients such as fiber are all carbohydrates. Eating plenty of vegetables, grains, and fruits-along with lean or plant-based protein sources-is one good way to achieve a healthy balanced diet. A healthy diet consisting of nutrient-dense foods ensures that you can get the nutrients you need for optimal health without overconsuming calories. This dietary approach is crucial for weight maintenance. The banana provides electrolytes, fiber, and prebiotics, while the jellybeans provide just 200 calories of sugar. In other words, you should be trying to consume more energy-dense calories or calories that contain a lot of nutrients per calorie rather than empty calories.įor example, if choosing a 200-calorie snack, 200 calories from jellybeans are not the same as 200 calories from a banana.
The quality of your food should always be considered for the goals of weight loss, weight gain, or weight maintenance.

Referring to a particular food or meal as having a certain number of calories dictates how much energy will be released by the nutrients in that food or full meal once digested and absorbed by the gastrointestinal tract.Īll calories are not the same some are quality calories, meaning they provide more nutrients per calorie than others. Kilocalories, or kcal, is the term used for measuring food energy. From a scientific perspective, a calorie is a unit of energy and is the amount needed to raise the temperature of one kilogram of water one degree Celsius.
