Calories - The Basics
Before I leave you to delve into this blog I’d like add that I am not here to tell you or condone calorie counting, as it can become very destructive and turn into a obsession rather than listening to your body! I am providing you with a brief understanding on what a calorie is and how tracking your intake can make a impact on your health, both positively and negatively.
To lose weight, you need to eat fewer calories than you burn. In theory, this sounds simple. However learning and understanding how to manage your intake of food can prove to be a tricky task! As we are constantly bombarded with information whether it be from friends, TV, magazines or social networks about calories it can makes it hard to know what’s right and what’s wrong!
Firstly, what is a calorie?
A calorie is a measure of energy. In science, it's defined as the amount of energy required to raise the temperature of 1 kilogram of water by 1 degree Celsius. We use calories that we eat and drink for essential functions such as breathing and thinking, as well as day-to-day activities such as walking, talking and eating! Excess intake of calories causes what you eat to be stored as fat therefore consistently eating more than you burn will cause weight gain overtime.
The United States government states that the average man needs 2,700 kcal per day and the average woman needs 2,200 kcal per day.
Keep in mind not everybody needs the same number of calories each day! People have different metabolisms that burn energy at different rates, and some people have more active lifestyles than others.
The recommended intake of calories per day depends on several factors, including:
• overall general health
• physical activity demands
• sex
• weight
• height
• body shape
Your body needs calories to survive! Without energy the cells within your body would begin to die, the function of your heart and lungs would stop and your organs would not be able to carry out the basic processes needed for living!
Now, not all calories are equal! The number of calories in food tell us how much potential energy the contain but not only calories that are important, the substance from which the calories is taken from is vital! These so called “empty” calories are those that provide energy but very little nutritional value. The elements of food that provide empty calories contain next to no dietary fiber, amino acids, antioxidants, minerals or vitamins! Empty calories can be made up of solid fats and added sugars. Solid fats are either naturally found in foods or can be added when foods are processed. Added sugars are sugars and syrups that are added then food or beverages are processed!
• Cakes, cookies, pastries, and donuts (contain both solid fat and added sugars)
• Sodas, energy drinks, sports drinks, and fruit drinks (contain added sugars)
• Cheese (contains solid fat)
• Pizza (contains solid fat)
• Ice cream (contains both solid fat and added sugars)
• Sausages, hot dogs, bacon, and ribs (contain solid fat)
The foods and beverages above are the main sources of empty calories but many can be found in no solid fat or added sugar products such as low-fat yogurt, no fat cheese or sugar free soft drink.
Choosing unsweetened applesauce or extra lean ground beef, can help keep your intake of added sugars and solid fats low but remember a small amount of empty calories is okay and won’t kill you! It is important to limit empty calories to the amount that fits your calorie and nutrient needs.
The main thing I would like you to take away from this blog is to ensure your diet is filled with whole, nutrient dense foods which will help you limit your intake of empty calorie foods!
Ditch counting calories and ....
• Opt for nutrient-dense options that our great-grandparents would recognise as food
• Go for a wide variety of in-season produce and ingredients
• Cook, which really is the key to it all
• Cut out processed foods
• Focus on regaining our natural appetite and cutting the cravings
