Calories / Food Content

I have included links to American Government Websites as well as NHS websites.

Calories are a measure of the amount of enery in food. Though we all talk about calories actually we are talking about kilocalories.  Not all calories are equal since the complexity and texture of the food can influence the net amount of energy that we absorb.

How many calories do we need ?

This varies according to your age,  weight, gender, job and activity level.

Typically 2000 for a woman, 2500 for a man, and less for children.

To lose weight look at cutting calorie intake by about by upto 600 calories per day.

Aim to lose no more than 0.5-1kg (1-2lb) a week .

One calorie counter book suggested :

Sedentary men                2300 (retired) to 3000 (building workers)

Moderately active men 2950 -300 (postmen, farm workers)

Very active men               3250 – 3600 ( steel workers – some building workers )

You can use the exercise-calorie counter to work out your energy requirements.

How much weight can I expect to lose ?

If you work on the basis that you burn non-fats ( which have less calories per 100g weight) 1st when restricting your food intake the initial weight loss will be more. When you have changed your lifestyle for a while, you will then start to burn of fat. As this has more energy per unit weight, your weight will not decrease as quickly. Exercise will help you maintain your weight loss.

Working backwards, if oil as 828 calories per 100g, if you reduce your calorie intake by 600 calories per day, and if it was all equivalent to oil it would be 70g loss per day /~1/2 kg per week.

Portion size

I bought a cheap weighing machine for £5 which was small and unobtrusive. This allows me to see what my food weighs easily an how much I am having. The aim is not to be obsessive about it but just to have a rough idea of what 100g looks like. Otherwise the only way people know what a portion size is via the sizes of bowls or what their family and friends eat.
,
We don’t notice what we eat. I recently watched a BBC Programme called The men who made us fat. What I felt it said was that we tend to eat whatever is put in front of us and do not make allowances elsewhere.  The portion sizes available have gone up.e.g. even a coca-cola portion was 75mls and is now upto 2l in some American takeaways.

The food companies like selling bulk cheap as it increases their turnover and take less profit on these bulk purchases comparatively. We buy these as we feel that the offers are better value. We  eat all of the food and do not compensate or share. The programme included a dietician who spoke of how they had organised portion sizes to double overthe course of a week and people did not notice and ate all the food.
