This one really drives me crazy. When it comes to considering which foods to eat or not eat, we should consider all foods on the planet in two ways. First – is the food good or bad for your body and secondly – what is the calorie value of the food?

First question – Is the food good for you? The amount of salt, saturated or trans fat, sugar ect. in any food has absolutely nothing to do with adding or reducing body fat. High amounts of these indicate that the food is not good for your system or that it is an unhealthy choice. In other words, consumption of these foods could lead to health problems such as heart disease, hypertension and many other conditions.

Second question –What is the calorie value of any given food?

 This is the only consideration when it comes to adding or reducing body fat.  It is merely a matter of physics, or heat energy. Any human body, no matter what size or age requires a certain amount of calories or energy to be in balance. Let’s call this your ”maintenance calorie level.” If you eat more than this amount, you will store the number of calories over your maintenance calorie level as fat. If you eat less than your calorie maintenance level, your body will use its storage or body fat to get you back up to calorie maintenance level for the day.

 Here’s an example, Say that your ”caloric maintenance” level is 2000 calories/day.  If you eat 2000 cal today, you will not store any extra fat or burn any stored body fat. You will be in balance. If you eat 2100 cal today you will store 100 calories as body fat. When you accumulatte a total of 3500 extra calories you will have added 1 pound of fat. On the other hand, if you eat 1900 cal,today your body will be forced to use 100 calories of existing body fat and when it uses 3500 over time, you will have lost 1 pound of fat.

In this blog I’d like to explain how the body stores or burns body fat, I will use the truth and absolute science of calories to explain this.

The best way to do this is to use a typical person, as an example. Our example is a female that is 25 years old and weighs 140 pounds.

Based on the formula: pounds of body weight divided by 2.2 x .9 x 24, our subject would have a 10% above sedentary caloric maintenance need of about 1400 cal per day. For our purposes, let’s assume this is absolutely correct, not accounting for any extra daily activity level, cost of digestion, etc..

We as humans are designed to be able to store fat in the event of a season without food, a long cold winter, a famine, or the like. Based on my research, I think this is between 10 and 20 pounds of fat. It’s pretty obvious that most of us have much more than this.

Now, back to our subject. If she eats 1500 cal today (100 above her maintenance need) she will store 100 cal worth of fat. Conversely, if she 1300 cal today her body will take 100 cal from storage (her body’s fat stores). We know that it takes 3500 cal to constitute 1 pound of fat. Now just do the math. If our subject eats 1500 cal per day for 35 days, that’s 35×100 or 3500 excess calories over 35 days. She will gain 1 pound of fat in this time frame. If she eats 1300 per day for 35 days her body will use 1 pound of what is stored in her system. It really is that simple.

You may say, why doesn’t she just eat nothing for a few days and she will lose it much faster? This is true. However, if you eat greater than 1000 cal less than your caloric need each day you will begin to burn muscle for energy. This is because the body has a limited capacity to convert stored body fat to energy. It can only convert about 1000 cal per day to usable energy running at maximum efficiency. Also, the less you eat in volume, the less likely you are to get enough nutrition (vitamins, minerals, enzymes and phytonutrients) in total and variety.

The only situations where this is not valid are when medications are involved that affect the amount of water your body contains (excess fluid or dehydration) or the subject has a diagnosed thyroid or metabolism problem. I will address these issues in another blog.
