"The calorie is a unit of energy that originated from the obsolete caloric theory of heat."
A unit of measurement used to quantify the amount of energy obtained from food and expended by the body through physical activity.
Basics of Calories: Understanding what a calorie is, and why it is important in the context of nutrition and cooking.
Calorie Intake: Understanding how many calories a person needs to consume each day to maintain their weight, or to lose or gain weight.
Calorie Counting: Learning how to count calories in foods and drinks, and how to track calorie intake using various tools and techniques.
Macronutrients: Understanding the three macronutrients: carbohydrates, proteins, and fats, and how they contribute to total calorie intake.
Micronutrients: Understanding the importance of micronutrients like vitamins and minerals, and how they affect calorie intake and overall health.
Energy Balance: Understanding the concept of energy balance, which is the relationship between calorie intake and calorie expenditure, and how it affects weight and health.
Calorie-dense and Calorie-light Foods: Learning about foods that are high in calories, and how to make healthier choices by choosing calorie-light foods.
Portion Control: Learning how to control portion sizes to ensure that calorie intake is consistent with overall calorie needs.
Cooking Techniques: Learning how to cook in a way that reduces calorie intake, such as baking or grilling instead of frying.
Healthy Recipes: Finding and trying out healthy recipes that are both nutritious and calorie-friendly.
Calorie Apps: Exploring apps that help track calorie intake and provide personalized recommendations for healthy eating.
Eating Out: Learning how to make healthy choices when eating out, and how to estimate calorie intake when dining out.
Food Labels: Understanding how to read food labels and interpret information about calories and other nutrients.
Mindful Eating: Learning how to eat mindfully, paying attention to hunger and fullness cues, and avoiding overeating.
Body Composition: Understanding how body composition affects calorie needs, and how to adjust calorie intake based on changes in body composition.
Carbohydrates: Carbohydrates provide 4 calories per gram and are found in foods such as bread, pasta, potatoes, and fruits.
Proteins: Proteins provide 4 calories per gram and are found in foods such as meat, fish, beans, and nuts.
Fats: Fats provide 9 calories per gram and are found in foods such as butter, oil, nuts, and cheese.
"The large calorie, food calorie, dietary calorie, or kilogram calorie was originally defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius (or one kelvin). The small calorie or gram calorie was defined as the amount of heat needed to cause the same increase in one gram of water."
"Thus, 1 large calorie is equal to 1000 small calories."
"It is generally used in publications and package labels to express the energy value of foods in per serving or per weight, recommended dietary caloric intake, metabolic rates, etc."
"Some authors recommend the spelling Calorie and the symbol Cal (both with a capital C) if the large calorie is meant, to avoid confusion."
"In physics and chemistry, the word calorie and its symbol usually refer to the small unit; the large one being called kilocalorie."
"The kilocalorie is not officially part of the metric system (SI)."
"The SI unit of energy, the joule (J), replaced the kilocalorie in many uses."
"In thermochemistry and nutrition it is now generally assumed that one (small) calorie (thermochemical calorie) is equal to exactly 4.184 J."
"One kilocalorie (one large calorie) is 4184 J, or 4.184 kJ."

"The word calorie and its symbol usually refer to the small unit; the large one being called kilocalorie."
"The joule (J) is the prevailing unit of energy in the metric system (SI)."
"One (small) calorie (thermochemical calorie) is equal to exactly 4.184 J."
"One kilocalorie (one large calorie) is 4184 J, or 4.184 kJ."
"The precise equivalence between calories and joules has varied over the years, but in thermochemistry and nutrition it is now generally assumed..."
