They appear on restaurant menus, milk cartons and bags of baby carrots. A calorie is the measure of stored energy in something — energy that can be released as heat when burned. A cup of frozen peas has a very different temperature than a cup of cooked peas.
But both should contain the same number of calories or stored energy. The term calorie on food labels is short for kilocalorie. A kilocalorie is the amount of energy it takes to raise the temperature of one kilogram 2.
It does, however, chemically break down food into sugars. The body then releases the energy pent up in those sugars to fuel processes and activities throughout each hour of the day.
Food contains three main types of nutrients that deliver energy: fats, proteins and carbohydrates which are often simply called carbs. Different foods go through different biochemical pathways, some of which are inefficient and cause energy calories to be lost as heat 1.
Even more important is the fact that different foods and macronutrients have a major effect on the hormones and brain centers that control hunger and eating behavior. The foods you eat can have a huge impact on the biological processes that control when, what and how much you eat. But the way they are metabolized in the body is completely different 2.
As you can see: the same number of calories — vastly different effects on hunger, hormones and metabolic health. Keep in mind that fructose only has negative effects when eaten in excessive amounts. Added sugar and candy are its largest dietary sources. Even though fructose and glucose provide the same number of calories, fructose has far more negative effects on hormones, appetite and metabolic health.
The metabolic pathways for protein are less efficient than the metabolic pathways for carbs and fat. The thermic effect of food is a measure of how much different foods increase energy expenditure, due to the energy required to digest, absorb and metabolize the nutrients. Here is the thermic effect of the different macronutrients 7 :. Studies show that high-protein diets boost metabolism by 80— calories per day, compared to lower-protein diets 8 , 9.
Protein calories are less fattening than calories from carbs and fat, because protein takes more energy to metabolize. Whole foods also require more energy to digest than processed foods.
Studies show that protein is by far the most filling macronutrient 10 , If you increase your protein intake, you start losing weight without counting calories or controlling portions.
Protein puts fat loss on autopilot 12 , Increased protein can lead to drastically reduced appetite and cause automatic weight loss without the need for calorie counting or portion control.
Different foods have different effects on satiety. This means some foods will give you a greater feeling of fullness. This is a key example of how the food choices you make can have a huge impact on the total calories you end up consuming.
There are many factors that determine the satiety value of different foods, which is measured on a scale called the satiety index The satiety index is a measure of the ability of foods to reduce hunger, increase feelings of fullness and reduce calorie intake for the next few hours.
If you eat foods that are low on the satiety index, then you will be hungrier and end up eating more. If you choose foods that are high on the satiety index, you will end up eating less and losing weight. If beer is not your drink of choice, you can use this calorie calculator provided by the National Institute on Alcohol Abuse and Alcoholism to work out how many calories alcohol adds to your diet.
There are ways of sourcing products with less solid fat or empty sugars. Rather than choosing the standard hot dog or a fatty cheese, for example, a person could choose low-fat options for either. However, even the lower-fat options are no replacement for calories consumed from sources that also provide nutritional benefit.
One recent study showed that drinking more than one sugar-sweetened beverage a day increases your risk of high blood pressure. The intake of empty calories can be avoided or dramatically reduced by incorporating fresh, healthy food and drink into the diet. Calories seem to be linked only to weight gain and obesity, but they are vital for health. They only pose a health risk when people consume more than the recommended amount. When thinking about calories, you should not be considering just your diet but also your level of physical activity.
A high intake of calories can be countered with regular, high-intensity exercise. Water loss during sleep can lead to people weighing less in the morning, while their bodies have also burned calories overnight. Learn more.
