What is a Calorie?
A calorie is a unit of energy. Rather confusingly, the term "calorie" may refer to two types of calorie - a large one and a small one!
Large Calories
The large "calorie" is the
amount of energy, or heat, it takes to raise the temperature of 1 kilogram gram
of water 1 degree Celsius (1.8 degrees Fahrenheit). One large calorie is equal
to 4,184 joules. It is commonly used in food energy measurement and appears on
food labels as "kilocalories." It may also be referred to a a "food
calorie."
Small Calories
The small "calorie" is the
amount of energy, or heat, it takes to raise the temperature of 1 gram of water
1 degree Celsius (1.8 degrees Fahrenheit). One small calorie is equal to 4.184
joules. It may also be referred to as an "energy calorie."
Calories are Simply Units of Energy
We tend to associate calories with
food, but anything containing energy contains calories. For example, a gallon
(about 4 liters) of gasoline contains about 31,000,000 calories!What is a Kilocalorie?
A kilocalorie is a unit of energy - it's 1 food calorie, or 1,000 energy calories. It's the energy necessary to raise the temperature of 1 kg of water by 1° Celsius (1.8 degrees Fahrenheit).
Kilocalorie = Large Calorie or Food
Calorie
A kilocalorie is synonymous with the term "large
calorie" or "food calorie."
The Value of Counting Calories for
Weight Control
All clinical weight loss studies as
well as most nutritionists and dietitians agree that calorie control is
essential for weight loss. Above all because losing weight by calorie counting
helps to build your knowledge and awareness of the calorie-content of the food
you eat.
Calorie Counting Accomodates All
Diets and Dieters
In addition, calorie counting is
flexible enough for almost any diet, lifestyle and food preference. There are
no forbidden foods when you count calories - all foods are allowed - as long as
you eat fewer calories than you burn up each day you will lose weight: that's a
fact.
Calorie Counting Helps Identify Foods
to Avoid
Although all foods are allowed -
providing the overall calorie total is under control - some foods are
calorie-dense, meaning they pack a lot of calories into a small volume. Candy
bars are a perfect example of a calorie-dense or high-density food. Calorie-dense
foods may be useful as an energy boost to counteract low blood-sugar levels,
but are not ideal for weight loss or for use in a calorie-controlled weight
loss diet.
Calorie Counting Helps Track Your
Weight
By listing your calorie-intake in a
food diary, you can track your weight loss progress and identify your weight
loss progress. Such a diary is also a valuable source of information for your
doctor or weight counselor.
Calorie Intake and Weight Loss
Generally speaking, the number of
calories you need when trying to lose weight depends upon (1) how heavy you are
and how much weight you wish to lose. (2) Your height. (3) Your age. (4) Your
gender. (5) The amount of exercise you perform. Even so for most people it is
advisable to maintain a calorie intake of 1200 plus calories per day.
Guide to Calories Needed When Trying
to Lose Weight
Here is a very approximate guide to
calories needed if you want to lose weight.Teens 1200-1800 calories per day
Women (non-active) 1000-1200 calories per day
Women (active) 1200-1500 calories per day
Men (non-active) 1200-1500 calories per day
Men (active) 1500-1800 calories per day
Calories and Weight Control
Here are some general suggestions for
how to reduce calories and control your weight.
Keep a Food & Exercise Diary
Weight loss studies show that making
a list of calories eaten in food and calories expended by exercise is a big
help in sticking to a weight loss program. It increases calorie-awareness,
boosts your motivation to keep dieting and helps to identify eating mistakes.
Eat a Healthy Diet
Diet nutritionists say that weight
loss is faster and more enduring if we follow a healthy diet. Don't forget
there are several vitamins and minerals that play an essential role in
metabolism and weight loss. So if you want to burn calories efficiently choose
a diet which contains foods from all the food groups and try to maintain a
sensible calorie intake between 1200 to 1500 calories per day.
Calories in One Pound of Fat
According to weight loss experts,
there are about 3500 calories in one pound of body fat. So, if you create a
3500-calorie deficit through diet, exercise or a combination of both, you will
lose one pound of body weight. In order to lose 2 pounds of weight, create a
calorie-deficit of 7000 calories, and so on.
Reduce Calories-In or Increase
Calories-Out (ideally, both)
The calorie deficit can be achieved
either by calorie-reduction alone, or by a combination of fewer calories-in
(diet) and more calories-out (exercise).
Foods That Burn Calories
Negative Calorie Foods
The idea of foods that burn more
calories than they contain (called 'negative calorie foods') does seem rather
far-fetched. That said, certain health experts have been advocating the
consumption of generous helpings of fruits and vegetables for years.
These foods, many of which are
considered negative calorie foods, are supposedly a great way to naturally
speed up your metabolism as well as maintain optimum health and fitness.
Foods That Burn Calories (Negative
Calorie Foods)
Asparagus, black beans, broccoli,
celery, grapefruit, green beanslentils, mangos, papayas, pineapple, spinach, strawberries
sweet potatoes, water melon, flounder, sea bass, lean steak.
