PINCH--1 + 1 Doesn't Equal Two With Calories

OK, Cylon Disciples, here's Pinch posting through The Cylon from an undisclosed location where from which he cannot post himself:


As we delve further and further into the nuances of nutrition one topic that continues to generate significant debate is calories.  What is a calorie? Are all calories equal? Should we count calories? Is counting calories even possible?  There are numerous questions and the topic of calories as been studied ad nauseum.  I'll do my best, partly based on science and partly on personal experience to break down the mystery of the calorie.

Technically, a calorie is defined as either of two units of heat energy or the energy needed to raise the temperature of 1 gram of water through 1 °C (now usually defined as 4.1868 joules).  Way too scientific for our purposes but the main take away from both of these is ENERGY, more specifically the energy we need to fuel the human body.  Calories are critical for the human body to function properly and just as critical, if not more so to monitoring weight gain/loss or athletic performance.  Counting calories, however is an inexact and time consuming science.  How many of us have time to measure and weigh every portion of every meal or snack we eat to get an exact calorie count?  Unless it is our profession I doubt any of us do which is why "counting calories" can be so maddening.  

To avoid the time commitment and frustration of counting calories it's helpful to take a step back and ask another question, "Are all calories the same?"  Scientifically, a calorie of pure sugar is equal to a calorie of protein, but their effects on the body are dramatically different.  It seems like common sense but think about it this way, would your body process calories, look the same and perform at the same level if you consumed 1,500 calories worth of candy bars versus 1,500 calories of lean meat, egg whites, fruits and vegetables?  Study after study has shown that diets based on the same amount of calories, but different proportions of fat, protein and carbohydrates result in different amounts of weight loss.  This is due to the fact that calories, in all their forms have different effects on the human body.  Sugar, for example, spikes insulin levels and tells the body to "store fat" while foods high in protein or fiber tell the body to "burn fat" because protein and fiber require the body to work that much harder to digest than do sugars and fat.  At the same time protein and fiber leave the body feeling "fuller" for a longer period of time and cut down on the amount of "cravings" that may lead to unhealthy or excessive caloric intake.  That seems like a great combination for those looking to lose weight or stay lean.

The easiest ways to "count" calories that doesn't want to make us pound our collective heads against our refrigerators are as follows:
1. Smaller portions - This may seem obvious but in today's world every restaurant and even many meals at home are WAY TOO BIG.  Some times the best solutions are the easiest ones that simply arise from common sense...when trying to lean down go to smaller portions.
2. Focus on Protein/Fiber/Natural Carbs - Putting it in perspective, one cup of chocolate ice cream has approximately 300 calories while one cup of broccoli has only 30 calories.  This is an extreme example but serves a much broader point that, in terms of calories it takes a lot of "healthy food" to equal a normal or even light amount of crappy food loaded with sugar and fat.  When eating healthy you can actually eat more food because it tends to be much lower in caloric content and at the same time loaded with the protein, vitamins and minerals that will help you excel in any athletic competition or training.

The great news is that if you use common sense and eat healthy foods you can actually eat more, but will likely be consuming less calories.  A lot of the above is based on articles I have read but at the same time based on personal experience.  When I played college football I ate 5-6 meals a day, but many of those meals were purposely loaded with pasta, bagels and foods heavy in fat and processed carbohydrates to pack the weight on and my caloric intake was somewhere around the 4,500 calorie/day range....and I weighed in around 265 pounds.  Now, however, I still eat 5-6 meals a day and rarely ever feel hungry but I avoid the breads, pastas and foods high in fats.  Because of that my caloric intake is roughly half of what it used to be and my weight is down to a fairly steady 212 pounds.  As an aside, while I don't focus on heavy squats anymore most of weight lifting numbers are similar to those I achieved when I weighed 265 pounds and was 14 years younger.  

The key to weight loss is burning more calories than we take in, but I've found that the key to sustaining that weight loss and enhancing athletic performance is largely found in the quality of the calories we consume.
