body 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.

I Can’t Stop Eating in the Evening

Are you one of those people who each almost nothing all day and then when you get home in the evening at dinner time you eat a huge meal followed by snacks and junk food later in the evening and by bedtime your stuffed? Well there’s a reason that you’re so voracious when you get home in the evenings. During the day eating almost nothing causes your body to think that you’re experiencing short term starvation, so when you finally see some food your body causes you to eat a greater volume because it thinks this may be the only thing you’ll get today. It truly is a survival mechanism. What can you do about this? Multiple small meals always works. Try it sometime. Try eating 3 or 4 small 3-400 calorie meals each 3-4 hours apart before 6pm. You’ll see that all of a sudden this tremendous psychological need to eat huge amounts is not there. In addition, you’ll see that you have greater energy during the day, plus you’ll get a more balanced flow of nutrients, fluid and fiber eating multiple small meals. Doing this will take some planning. However in today’s markets there are many food choices that make this easier. For example, all the 100 calorie packs you see advertised, plus there are hundreds of prepackaged bars and snacks some of which are actually healthy choices. These types of foods are convenient, you can store them for long periods of time and are pre-packaged, so you can take them with you anywhere you go. Just open and eat.
