Calories..
What are they and how many a day should we consume? A question asked all the time!!!
Some foods and beverages contain ‘empty calories’ such as alcohol and sweets because they contain lots of calories but no nutritional value whatsoever
A generic table shows below the daily recommended amounts of calories to be consumed per day:
Women Sedentary 2000
Women Active 2500
Men Sedentary 2500
Men Active 3000
A Calorie is ‘The unit of measurement of energy derived from digested food. Fat contains about twice as many calories per gram as protein or carbohydrate’.
Foods have carbohydrates, proteins, and fats. Some beverages have alcohol.
Carbohydrates have 4 calories per gram.
Proteins have 4 calories per gram.
Alcohol has 7 calories per gram.
Fat has 9 calories per gram.
The UK department of health estimates that a female requires on average 1940 calories per day and a male requires 2550 calories per day.
These figures vary greatly though depending on your lifestyle, your age, your body composition, your height and weight and your daily activity!!
If someone is very active and works out a lot or is constantly busy then they will be burning off more calories than say someone who is sedentary.
To lose weight you need to burn off more calories than you are consuming - leaving your body in a deficit. Easy!
When your body is in a deficit it has no choice but to consume some other form of energy such as your body’s fat resources - common sense really!!
