Nutrition Basics


Many people I have worked with do not understand why they are failing to lose weight. After all, they are working out. Maybe even a lot. And they are frustrated because they are not getting the results they expect.



If part of your fitness goal is to lose weight, it can be difficult to accomplish that through exercise alone, depending on what you eat.

Mathematically, it is not all that complicated. 



Suggested Relative Portion Ratios of Nutrient Groups - MyPlate.gov
It can be easier to understand if we look at food as “fuel,” and exercise as part of the “burning of fuel.” Mathematically, it is not all that complicated. During the course of a day, I personally consume approximately 2,500 calories. I established that number based on research from sources such as ChooseMyPlate.gov (which I highly recommend – more on that later).  If, on average, I also burn 2,500 calories per day through activity (and simply living), then I will neither gain nor lose weight. On the other hand, if and burn more than I consume – I will lose weight, and conversely, if I consume more than I burn, that fuel will be in excess and becomes stored as fat.

...it’s the combination of exercise coupled with disciplined fuel consumption that REALLY provides the big results.



Studies show that people, as a rule, underestimate how many calories they consume, and overestimate their exercise duration, intensity, and/or frequency. While exercise will help you burn calories while engaged in the activity and improve your metabolism so that you burn more calories even when you are not exercising – it’s the combination of exercise coupled with disciplined fuel consumption that REALLY provides the big results.



Let me use myself as an example: I teach a Spin Bike class, which is one of the best aerobic exercises available. During a 45-minute intense workout, I burn approximately 500 calories. If I follow that up with a “reward” of a gourmet burger – say a guacamole bacon burger registering in at 1,070 calories, medium French fries at about 450 calories, and a carbonated sugar beverage at 250 calories, I would have consumed 1,770 calories of my 2500 calorie target – leaving me with 730 for breakfast, lunch, snacks, dessert, and other beverages.

Please understand, I’m not a fanatic 
about counting calories.



Please understand, I’m not a fanatic about counting calories. On the other hand, I have a pretty good grasp of what food contains nutritionally and calorically, and I get the concept of the math. It’s just a fact that it takes 3,500 calories of unburned fuel to add a pound to your weight. And if I want to take a pound off, that requires I burn 3,500 calories beyond what I consume. 




As you probably know, food is made of nutrients that include carbohydrates, fats, and proteins. YOUR BODY NEEDS ALL OF THESE. Not too long ago, fad diets advocated avoiding carbohydrates. Bad idea; carbs are the primary fuel your body craves. A lot of athletes dramatically over consume protein. Protein is absolutely essential for your body. However, if a person consumes more protein than his or her body can utilize, guess how that protein gets stored? It gets converted to fat. Fats, or lipids, are also essential to the body. The good new is, they are easily found in foods – even in sources you don’t suspect, such as seeds.  The bad news is, many foods provide a fat overload that goes far beyond what the body needs, and that also gets stored. One key thing to remember is that our body is very efficient at holding onto excess fuel; it’s programmed to store it for you, just in case you plan on hibernating or something. And how does it store the excess you haven’t burned – whether it is in the initial form of carbohydrate, protein, or fat? Our storage system is fat, so even carbs and protein are converted to that form.



If you are attracted to some diet that advises you to avoid carbohydrates, protein, or fat – BEWARE! 
Carbohydrates

Unsaturated Fats
Carbohydrates serve as the body’s main source of fuel, are essential for the central nervous system, brain, kidney, muscles, and heart to function properly. Proteins serve as a source of nutrient necessary for tissue repair, growth, hormones, enzymes, the immune system, backup energy, and preserving lean muscle mass. Fats serve us providing the ability to absorb vitamins A, D, E & K, as reserve energy, cushioning organs, maintaining cell membranes, and for normal growth and development. (Saturated and trans fats have been scientifically linked to increased risk of heart disease. Whereas as unsaturated fats  such as those found in olive oil, seeds and nuts, avocados, and canola oil have been linked to a decrease in the risk of heart disease.)
Protein

I do NOT deprive myself of my favorite foods.



For me, I do NOT deprive myself of my favorite foods. That leads to roller coaster rides of weight loss followed by weight gain. I need to practice portion control. I still eat pizza once in awhile, but 2 pieces instead of 4 (or more). Ice cream is enjoyed in a smaller bowler – it still looks full. A half sandwich, along with fruit and vegetables, satisfies me completely; I don’t actually need the whole sandwich. Like most people who were raised by Depression Era parents, I was taught to “clean my plate” – meaning eat everything served – no waste. Consequently, I will obediently (and enjoyably) eat everything you put before me. Put 8 pancakes on my plate, and somehow, I’ll get those babies down. My point? I have to prepare the amount that is appropriate to eat, because if I follow a recipe that yields 6 servings in preparation for my wife and me, chances are good there won’t be much in the way of leftovers.



Finally, visit MyPlate.gov. You can use the “SuperTracker” to plug in several days of what you normally eat and run an analysis that provides you with really interesting information. Not only will you discover your caloric intake, a breakdown of what nutrient groups your meeting or deficient in, but the analysis will even let you know whether you are meeting your requirements for vitamins and minerals. It’s really a very cool and helpful online tool and very user friendly.
