Introduction
Before you continue, click here to update to the latest version NOW! 
The draft you are reading now is dated 20th Feb 2005

Now that you have updated, save the update to your desktop for ready access.  This utility is constantly being refined so ALWAYS update to the latest version every time you want to do some calorie accounting.

Be generous:  share with others
The primary aim of this package is to enable you to gain INDEPENDENCE and CONTROL over your weight loss and weight management program.  So that the maximum number of people can benefit, it is important that you forward this package (MYOBodyweight.htm) as an attachment extensively throughout your email networks. Even if the person you send it to has no need for it, the person they send it to might have a need.

Summary
If you have found the motivation to take control of your body's energy balance, the calculators and process below have been designed to enable you to get a firm grip of the information you need for success. Specifically it enables you to:

Step 1. calculate your energy expenditure from "metabolism"
Step 2. calculate your energy expenditure from activity and exercise
Step 3. calculate your energy income from food and drink
Step 4. view your energy deficit/credit per day and per week
Step 5. view your potential weight loss/gain per week
Step 6. discover which everyday snacks and treats can bankrupt all your hard work.


The MYOBodyweight Calorie Accounting Package is offered free of charge and has been constructed as a self-help utility.  With a small amount of self education (particularly the food exchanges), there is sufficient information below for you to successfully manage your own weight loss and weight maintenance program for decades.  Should you need additional help there are links to reliable and dependable websites.

Calorie Accounting 101: The Basics
In one kilogram of body fat there are about 7,000 Calories of energy.  Therefore to lose 1 kilogram of body fat, you need to create an energy deficit of about 7,000 Calories.  This can be achieved by an increase in activity/exercise (energy output) or a decrease in fuel intake (energy input), but it is best achieved by a combination of both. 

Why "dieting" doesn't work
If we only decrease our fuel intake as a method of causing an energy deficit our body responds as though we have entered a period of famine and goes into starvation/survival mode.  In other words, the body compensates for the decrease in fuel by automatically slowing down its metabolic processes, thereby conserving fuel for heart beat, breathing, heat production, etc so that it might survive starvation.  However, by combining increased activity with a moderate decrease in fuel intake, the body's metabolic rate continues to be stimulated which prevents the body from going into starvation mode.

By using a combination of decreased energy input ("eat better") and increased energy output ("move more") you can easily create an energy deficit of, say, 500 Calories per day.  This translates into a 3,500 Calorie deficit per week or a 14,000 Calorie deficit per month, which is equivalent to the amount of energy in 2 kgs of body fat.  This may not look like a lot on the scales but it's the equivalent to the weight of a 2 litre container of milk.  Try carrying one of those around with you all day!

Take Control
Weight loss and weight maintenance are achievable. Its all about being motivated sufficiently to take control of our body's energy balance, creating an energy deficit to lose weight, and once you have achieved your desired weight, keeping the balance between energy input and energy output to maintain your weight at that level.

Now, let's not procrastinate any longer, let's get started!!

TOTAL ENERGY REQUIREMENTS

Average of 3 methods (References 1,2,3 below)

The above calculator uses an estimated Ideal Body Weight (BMI of 22.5) to estimate your energy output via metabolism (breathing, heat generation, heart rate, etc).  Assuming you are overweight rather than a muscle-bound body builder, to use your actual body weight would overestimate your energy output from metabolism.  Unlike muscle tissue, body fat is relatively dormant (metabolically inactive) and does not contribute much to energy output.

To save a record of the above information, print now. 
None of the data is saved when you close this page.

An energy deficit that leads to the loss of between 0.500 kg and 1.000kg of body weight per week is ideal and more likely to be sustainable in the long term.

To help ensure that you are eating relatively healthily, energy intake from food for the duration of your program should not be less than 20 Calories per kg IBW (Ideal Body Weight:BMI = 22.5) per day.  It is far healthier to cause the required energy deficit through activity and exercise than by diet alone.

Step 5:  Review which foods/drinks can bankrupt all your hard work

The energy deficit calculated above is equivalent in calories to the following amounts of particular foods/drinks:

  Food Number of serves
  Meat Pie 170g (individual serve size) meat pies
or Coke, 375ml can/bottle cans of coke
or Potato Crisps, 30g packet packets of crisps
or Mars Bar, 60g Mars Bars
or Beer, full strength, 375ml can/stubby cans/stubbies of beer
or Doughnuts, 40g doughnuts
or Sweet Biscuits, 10g plain sweet biscuits
or Cake, 40g slice slices cake
or Chocolate, 50g (small bar) small chocolate bars
or Cream/Mayonnaise, 1 tablespoon (20g) tablespoons
or Soft Drink, 375 ml can cans soft drink
or Hot Chips, 10g each hot chips
or Icecream, 35g scoop scoops ice cream
or Alcoholic Drinks standard drinks
or Butter/Margarine/Oil, 20g tablespoons tablespoons

The lesson is here that you can sabotage all your hard work for the day just by (for example) drinking375ml cans/stubbies of full strength beer.

The other message is that there MIGHT be room for a little fun in your life, depending on whether you have EARNED it or not.
