The word calorie has a bad rap. We constantly come across calorie reduced or low calorie foods. And it's not uncommon to overhear someone gasp about the immense calorie content of certain foods, such as a rich and creamy desert, or a giant fast food burger.
All of this anti-calorie rhetoric therefore has made a lot of us pretty calorie-phobic; as soon as we see something that has lots of them, we run away. But is this wise?
Yes and no. Yes, it's wise in the sense that avoiding that double-layer chocolate fudge cake for desert is probably a good idea (actually, scratch that; it is a good idea).
The calories that come from the cake are really going to be the so-called empty calorie kind; which means that there's no real nutritional value that your body can squeeze out and make use of.
But in the bigger picture, it's unwise for your metabolism to become calorie-avoidant.
Why? Because your body is a marvelous machine that tries, at all times, to do what it can to make your life easier.
Indeed, while it may not always function at optimal levels (for a variety of reasons, including genetics), it still tries to do its very best. The body, for all of its limitations and so forth, is not a lazy thing!
With this in mind, the body is always trying to keep is alive and functioning in the manner that it deems to be healthiest.
And that's why if you suddenly decrease the amount of calories that you need, your body won't try to do more with less. In other words, your body won't respond in the way that you want it to: it won't necessarily provoke catabolism and thus reduce weight and fat cells.
Instead, your smart and wise body will try to keep you alive by slowing down its metabolism. It will simply believe that something is wrong – maybe you're trapped somewhere without food – and it will just begin to become very stingy with energy.
So what's the end result? If your body needs 2000 calories a day to survive, and you suddenly give it only 1000, it won't begin to burn off 1000 calories worth of cells that you have lying around on your love handles.
Instead, your body will slow down its metabolism. It will really try and get as much energy out of those 1000 calories, because it doesn't want to waste anything.
Physically, you'll naturally feel more tired because your body is being very miserly with energy, and will devote its 1000-calorie ration to essential systems, like blood and oxygen supply (and others).
Metabolically, you won't be burning off extra calories. In fact, you can actually gain weight by dramatically reducing your calorie intake!
The flipside of this, of course, is that you should consume a daily caloric intake that is proportionate to your body size, type, and weight loss goals.
And then, once you determine the amount of calories that you need (probably with the aid of a qualified nutritionist or fitness expert); you can provide that to your body via healthy, efficient calories.
For example, if your body needs 1500 calories per day, and one slice of double-fudge chocolate cake delivers a whopping 500 of those, then you can see that eating just one of these slices will take up a full 1/3rd of your daily caloric needs; and that's not good!
On the other hand, you can see that drinking a tasty fruit smoothy made with yogurt and nuts can deliver half as many calories, but provide you with essential nutrients, vitamins, and other elements that your body needs to healthily do its work.
