I love this article because it is clear and tells you exactly what you need to know about calories and how to help you loose the pounds. I put here the highlights of the article.
The calorie is a measure of energy available to the body. When you eat food, the number of calories it contains is actually the amount of energy units the food provides the body. The calorie is also the measure of energy that your body uses. Your body uses calories for many functions, such as breathing, pumping blood, resting, sitting, working, and exercising. So the calorie is used to measure both the amount of energy contained in foods, as well as the amount of energy your body uses.
The difference between the two is the Calorie Equation. When you eat more calories than you use, the rest is stored as fat and you gain weight. To lose weight, you simply need to use more calories than you eat so your body is free to call upon other energy sources – such as stored fat.
The above statement is very crucial to loosing weight. I need to use more calories.
Where Do Calories Come From? There are six classes of nutrients: carbohydrate, protein, fat, vitamins, minerals, and water. Of these six classes of nutrients, only 3 provide calories or energy for the body: carbohydrate, protein and fat:
- 1 gram of carbohydrate = 4 calories
- 1 gram of protein = 4 calories
- 1 gram of fat = 9 calories
Balancing the calories you take in with those you put out is the safest, healthiest way to control your weight – for the next two weeks, or the next 20 years. It takes about 3500 calories to make one pound of fat (neat info). So to lose one pound, you can:
- a) Burn 3500 excess calories (if you have a few hours to kill)
b) Eat 3500 fewer calories (starvation diet, anyone?)
c) A combination of exercise and diet (the best option)
I like the comparison :)
Starvation Mode. There is a common misperception that to lose weight, the lower the calories, the better. Ironically, the key may be eating more calories. You can actually hurt your body's ability to lose weight by going too low. Here's why. The body has a protective mechanism. When calories drop too low (we recommend a minimum of 1,200 for women and 1,500 for men) the body reacts as if it is starving and tries to conserve energy. It will lower your metabolism, conserve calories and fat, and you will not burn calories as quickly. This results in a slower weight loss or even no weight loss. This is what's know as "Starvation Mode."
This is why sudden less food intake can be damaging to your physical and emotional state. We need to cut the "bad" food slowly. Otherwise body thinks I have moved out to a remote place with no fast food chains around.
When calorie intake falls below 1,200 to 1,500 calories a day, it is also extremely difficult to follow a balanced diet and obtain all the nutrients that are needed by the body to stay strong and energetic and prevent disease. These very low calorie intakes can also lead to other health problems such as eating disorders, gout, gallstones, and heart complications. For these reasons, we strongly suggests not going below 1,200 calories daily for women and 1,500 calories daily for men.
Muscle Power. Fat tissue lowers the rate at which one burns calories, because fat tissue requires less oxygen and is very inactive. On the other hand, muscle is a more physically and metabolically active tissue. It therefore burns more calories than fat. Through exercise, especially strength and resistance exercise, you can decrease the amount of fat in your body and increase the amount of muscle. This will then help you burn more calories each and every day, even when you’re not exercising.
Muscle also weighs more than fat. Near the beginning of your program, you may gain some weight after strength exercising. This is perfectly normal. As the composition of your body changes from fat to muscle, the muscle will help burn off that remaining fat at a faster rate, uncovering your lean, fit muscles.
Muscle is good. You will look lean :) thus, better fit your dream outfit!
On The Dreaded Plateau? Hitting a plateau during a weight loss program is normal (though it can still be frustrating). Your body requires fewer calories to function as your weight decreases. It needs time to adjust to all the healthy changes that are occurring due to the weight loss. So continuing to follow the same eating and exercise patterns won’t work forever.
Everyone’s body will adjust differently. To jump-start your metabolism and break out of the plateau, you may need to select a different form of exercise to stimulate other muscle groups to become more active. Do not become discouraged; this may take several weeks or months. Stay focused on all the positive things you have accomplished. Your goal during plateaus is to try not to gain any pounds back. Get energized with a brisk walk. Add on a little jogging or running. Try a new piece of equipment. Test out a strength training routine. Try a new activity like dancing, rollerblading, or cross-country skiing. Start taking the stairs at home and work.
I'm worried about the plateau stage. I had this before and I actually gain more weight because I gave up my routine. Variety is key. I need my friends to keep me motivated.
