Calories. What they are... and why we need them!

With a small ‘c’, a calorie is the amount of energy required to heat 1g of water by 1 degree celcius. Calorie with a capital ‘C’ is really a kilocalorie: 1000 calories, the amount of energy required to heat 1kg of water by 1 degree celcius (or 4.2kJ).

We all need to eat to live (not the other way round). With CALiCO and Exclusively Ladies we do not make food the enemy. Going without nutrition or using wacky diet plans doesn’t work, but eating sensibly does….You will probably be surprised by how much you can actually eat without loading on the calories... Its amazing what you can replace for a pizza!!

It is interesting to consider the amount of energy we need to consume just to keep our bodies working before we even expend any energy during our daily routine.

The Harris-Benedict Equation is one of a number of formula used to calculate the Resting Energy Expenditure (REE) in Calories per day.

The REE represents the Calories required in 24 hours of relative inactivity.

So add some activity into your routine, and you see that just like a car without petrol we are never going to be effective without fuel. Don’t view every morsel as a threat, as long as you remember CALiCO and ensure the CALories In equal the Calories Out you won’t go far wrong.
