This is a very common question in the fitness world.
Quite frankly just losing weight is very easy to do.
This comes down to:
Calories in, is less then, Calories out.
Therefore
Calories in = how much you eat.
Calories out = how much energy your body uses.
What is Calories?
Calories is the energy contained in food, this is usually defined in Kj’s (kilojoules – where K is defining 1000) on food packaging.
There is approximately 4.184joules to 1 calorie.
Therefore when you look at food packaging on it if it has Kj’s, divide it by 4.184 to see how many calories are in it.
Some example calories:
Two pieces of toast has about 500Kj’s which equates to 121 calories.
Coke has 1080Kj’s which equates to roughly 260 calories.
Big Mac has 2060Kj’s which equates to roughly 500 calories.
An average foot long subway has roughly 2500Kj’s which equates to 605 calories.
How many calories do I burn in a day?
Unfortunately without seeing you and measuring you up I can not even start to give you an estimate of how many calories you would burn in a day.
This depends on a multitude of things:
- Gender
- Genetics
- Muscle mass
- Level of activity
These are only a few things that determine how many calories you burn in one day.
If you have a look around it states that you may burn anywhere between 1500 ~ 2000 calories in a day for a average person, you can use this as a guideline, but a guideline only as I mentioned there are so many factors which contribute towards this.
So if you were only looking to lose weight this would be a form of a starting point.
But remember this is only to lose weight on the scales, there are hidden dangers to this, but this article will hopefully make you aware of how to read packaging on food labels!
