What is a Calorie?

This is a good question. We can see calories on almost any food product. Some are tougher than others. Vegetables, fruits, produce, meats, etc. don't have the calories on the package. What on earth would you do if you wanted to count them??
Think of calories as energy. Food calories listed on packages are known as a kilocalories. When we exercise fitness charts show that we burn 100 calories for every mile we jog. The faster you run, the more calories you burn. If you run slower, you will burn few calories.

Here is a Caloric Breakdown:
1 g Carbohydrates: 4 calories
1 g Protein: 4 calories
1 g Fat: 9 calories

Our bodies can burn calories by a metabolic processes where enzymes break carbs into sugars, the fats into glycerol, fatty acids and proteins into amino acids. The process is finished by the rest broken into smaller bits and flows through your bloodstreams cells. It's mixed with oxygen to release the stored energy.

How many calories do we need to intake. So many people have so many responses. The daily average is set at 2,000. Height, weight, gender and exercise level can make a big difference in this amount.

How do you loose/gain weight? If you take in more calories than you burn, you will gain weight. If you take less calories than you burn, you will loose weight. Is that it? 3,500 calories equals one pound of fat. If you exercise more and eat less your one pound of fat is converted into energy and poof...the one pound is gone.. Cya.

The amount of exercise is important. The quality of exercise can make a big difference too. There are tons of charts to help gage how many calories you can burn.

That was very informative, I starting counting my calories again. That trip home took a toll on me.

I signed up for Coeur d'Alene Ironman one year in advance. If you want to register online expect to do it either on race day or the day after.

Coeur d'Alene doesn't sell out as fast as the other race. I think it sold out within a week.

A calorie is also the amount of energy required to raise 1 gm of water by 1 degree Celsius. The calorie we think of in foods is actually a KCal or 1000 cals!

Great Post Eric,

This is the stuff that people need to have access to. If more people knew how simple this process was, I believe that most people would strive to be more fit. How is everything else going?

For anon posting on your blog about signing up for races;

Just expect to make a weekend excursion on the year previous that you want to race. Even volunteer for the event if you want. I have tried to sign up twice now for online registration (FL for 08 and AZ for Nov 08), and they sold out within 1 minute or less online. Basically everyone went to the events physically and signed up to make sure that they had a slot. I am planning on going to CdA this June to volunteer so I can get a slot for 09.
