Calories 101

The average human is confronted by calories everywhere they go. You go to the supermarket and there they are, stamped on every box and bottle. Restaurants now print calorie counts on menus. You hop on the treadmill and watch your calories burned click upward.

But just what are calories?

A calorie is simply a unit of measurement for heat. To apply this concept to foods like sandwiches, scientists used to set food on fire. They would then gauge how well the flaming sample warmed a water bath. The warmer the water, the more calories the food contained. Today, a food’s calorie count is estimated from its carbohydrate, protein, and fat content. So what is a calorie on a Nutrition label, simply the Amount of heat required to raise 1 kilogram of water by 1 degree Celsius.

So let’s break it down: Our fuel “calories” comes from three sources: protein, carbohydrates, and fat.

Example:

For every 100 Carbohydrate calories you consume, your body expends 5 to 10 in digestion.

For every 100 Protein calories you consume, your body needs 20 to 30 for digestion

Carbohydrates and Fat gives up their calories easily: They’re built to supply quick energy and are absorbed by the body quickly resulting in greater risk for increasing weight

+RefIt Tip: If you want to lose weight, make protein a priority at every meal. And avoid high calorie foods such as Junk Food, Ice Cream, Candy, Fried Food etc.

Most of your calories burn at a constant, fueling the automated processes that keep you alive—that is, your metabolism. Over 60 to 70 percent of our total caloric expenditure goes toward normal bodily functions which includes replacing old tissue, transporting oxygen, and so on. You also loose calories on daily activities, such as the calories you burn on daily motions you make outside the gym—the calories you burn while making breakfast, playing football in the office, or chasing the bus. Even the most fanatical fitness nuts burn no more than 30 percent of their daily calories at the gym. SO what’s your next move? Set a goal and stick to it in terms of your calorie needs per day, pay attention to nutrition labels and make sure you are feeding your body right and healthier! Simply Get ReFit.
