Some Carbohydrates Are Better Than Others When Trying To Lose Weight
If you are trying to lose weight, maintaining a steady blood sugar level is a very important component of your dieting effort. While your body breaks down all digestible carbohydrates into blood sugar, some are converted into blood sugar faster than others. Thus, some carbohydrates cause a spike in your blood sugar level which causes you to feel hungry faster and to crave more sugary foods. While other carbohydrates are converted into blood sugar more slowly leveling out you blood sugar resulting in less hunger and less food cravings.
For this reason, the Glycemic Index (GI) was developed to classify how quickly your body converts carbohydrates into blood sugar as compared to pure glucose. Glucose has a GI of 100 and all other carbohydrate based foods are ranked against it. Foods with a score of 70 or more are defined as having a high GI while those with a score of 55 or less are considered as low.
Eating lots of food with a high GI causes spikes in your blood sugar level which can lead to many health issues such as type 2 diabetes, heart disease, and obesity. While eating low GI foods causes your blood sugar level to stay even thus, keeping your energy level balanced and causing you to fill fuller longer between meals. The following are some additional benefits of eating low GI carbohydrates.
· Helps you to lose and manage your weight.
· Increases your body's sensitivity to insulin.
· Decreases your risk of developing type 2 diabetes.
· Reduces your risk of heart disease.
· Improves your blood cholesterol levels
· Reduces hunger and keep you fuller for longer.
· Helps you prolong physical activity.
· Helps you to re-fuel your carbohydrate stores after exercise.
You can get the GI rating of hundreds of carbohydrate based foods from the Glycemic Index Foundation, sponsored by the University of Sydney in Australia. They maintain a searchable database of over 1600 entries at http://www.glycemicindex.com.
Balancing The Carbohydrates In Your Diet Is Very Important

Maintaining a steady blood sugar level is very important component of your dieting effort. While you’ve just seen in my previous post that your body breaks down all digestible carbohydrates into blood sugar, some are converted into blood sugar faster than others. Thus, some carbohydrates cause a spike in your blood sugar level which causes you to feel hungry faster and to crave more sugary foods. While other carbohydrates are converted into blood sugar more slowly leveling out you blood sugar resulting in less hunger and less food cravings.

The GI is very interesting because some foods that you intuitively think would have a high rating do not. For instance, fructose which is fruit sugar has a minimal effect on blood sugar while white bread and French-fried potatoes are nearly converted to blood sugar as fast as pure glucose. In other words, you can’t classify foods as having a high or low GI according to the sweetness of taste. Many factors affect a foods GI such as:
· Processing: Grains that have been milled and refined have a higher GI
· Type of starch: Starches come in many different configurations. Some are easier to break into sugar molecules than others. For example, starch in potatoes is digested and absorbed into the bloodstream relatively quickly.
· Fiber content: The sugars in fiber are linked in a way that is hard for your body to break down. Thus, the more fiber a food has, the less digestible carbohydrate, and consequently the less sugar it can deliver into your blood stream.
· Fat and acid content: The more fat or acid a food contains, the slower its carbohydrates are converted to sugar and absorbed into your bloodstream.
· Physical form: Finely ground grain is more rapidly digested, and so has a higher GI than more coarsely ground grain.
The basic technique for eating the low GI way is simply a "this for that" approach - i.e., swapping high GI carbohydrates for low GI carbohydrates. You don't need to count numbers or do any sort of mental arithmetic to make sure you are eating a healthy, low GI diet. Follow these easy to implement suggestions.
· Use breakfast cereals based on oats, barley and bran
· Use breads with whole-grains, stone-ground flour, sour dough
· Reduce the amount of potatoes you eat
· Enjoy all other types of fruit and vegetables
· Use brown rice
· Enjoy whole-wheat pasta and noodles
· Eat plenty of salad vegetables with a vinaigrette dressing
As you can see it’s important to include the right kind of carbohydrates as part of your daily intake. I generally get about 50 percent of my daily calorie intake from low to medium glycemic index carbohydrates. I find that this amount gives me plenty of energy for all my daily activities. You’ll find that eating low to medium GI carbohydrates levels out your energy and keeps you from those highs and low points throughout the day.
So now you ask, how many grams of carbohydrates can I eat daily? Let me show you in the following example. Let’s assume you eat 1800 calories each day and 50 percent of those calories come from carbohydrates. So that’s 900 calories you consume in carbohydrates each day. There are 4 calories in each gram of carbohydrates. Now, divide 900 by 4 and that equates to 225 grams of carbohydrates each day. Next use the USDA’s National Nutritional Database as I mentioned above to calculate your serving sizes and it’s easy to start balancing the amount of carbohydrates in your diet.
Carbohydrates and How Your Body Uses Them
The popularity of the Atkins, South Beach, and other low-carbohydrate diets has probably led you to believe that carbohydrates are “bad” for you. Just reading the hype in the media would make you think that carbohydrates are the cause of the obesity epidemic throughout the United States.
Eating a lot of easily- digested carbohydrates from white bread, white rice, pastries, sugared sodas, and other highly processed foods may contribute to your weight gain, and therefore, interfere with your efforts to lose weight. On the contrary, consuming whole grains, beans, fruits, vegetables, and other intact carbohydrates promotes good health. As I mentioned in my previous post, a healthy diet is about balance and moderation. A basic knowledge of what carbohydrates are and how you body uses them is essential to understanding how to balance them in your diet.
Carbohydrates are essential nutrients that are excellent sources of energy (measured as calories) for your body; they are the preferred fuel for your brain and nervous system. Carbohydrates are found in an array of foods such as bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and desserts. The most common and abundant forms are classified as sugars, fibers, and starches.
The basic building block of every carbohydrate is a sugar molecule, a simple union of carbon, hydrogen, and oxygen. Starches and fibers forms of carbohydrates are essentially chains of sugar molecules, some containing hundreds.
As mentioned above, most carbohydrates come from plant sources and are in the form of sugars, starches, and fibers. Sugars, also called simple carbohydrates, include fruit sugar (fructose), corn or grape sugar (dextrose or glucose), and table sugar (sucrose). Starches, also known as complex carbohydrates, include everything made of three or more linked sugars. Starches include foods such as breads, cereals, grains, pasta, rice, and flour. Fibers are technically classified as a starch because they are complex carbohydrates that your body cannot breakdown into sugar molecules. Fibers are more abundant in whole grains, legumes, and vegetables.
Your body breaks down all carbohydrates, except for fibers, into single sugar molecules regardless of their source. These simple sugars are further converted into glucose, also known as blood sugar. Your body is designed to use blood sugar as a universal source of fuel for energy.
Fiber is the form of carbohydrate that your body cannot break down into simple sugar molecules. It passes through your body undigested. Fiber comes in two varieties: soluble, which dissolves in water, and insoluble, which does not. Although neither type provides energy for your body, they both promote health in many ways. Soluble fiber binds to fatty substances in your intestines and carries them out as waste, thus lowering your low-density lipoprotein (LDL, or bad cholesterol). It also helps regulate your body’s use of sugars, helping you to keep your hunger and blood sugar in check. Insoluble fiber helps push food through your intestinal tract, promoting regularity and helping to prevent constipation.
Here’s what happens when you eat a food containing carbohydrates. Your digestive system breaks down the digestible ones into sugar, which then enters your blood. As your blood sugar level rises, specials cells in your pancreas churn out insulin, a hormone that signals your cells to absorb the blood sugar for energy or for storage. As your cells soak-up the blood sugar, its level in your bloodstream begins to fall. Now, your pancreas starts making another hormone called glucagon, which signals your liver to start releasing stored blood sugar. This interplay of insulin and glucagon ensures that cells throughout your body have a steady supply of blood sugar.

Balance and Moderation the Key to a Healthy Diet, Part 2 - Protein
Image by Cam Switzer via Flickr
In this segment we'll talk about protein. Protein is a necessary part of every living cell in your body. Next to water, protein comprises the greatest portion of your body weight. Protein substances make up your muscles, ligaments, tendons, organs, glands, nails, hair, and many vital body fluids. It is essential for growth, repair, and healing of your bones, tissues, and cells. So, you can see the proper amount of protein in your diet is vital for your health and well-being.
Protein is comprised of building-blocks called amino acids. There are approximately twenty-eight commonly know amino acids that your body uses to create all the various combinations of proteins needed for survival. These commonly known amino acids are further classified as essential and nonessential amino acids. Nonessential amino acids can be produced in your body, while essential amino acids cannot be produced in your body and must be obtained from the foods you eat.
The sources of protein in your diet are classified as complete or incomplete. Complete proteins contain all the essential amino acids and are mostly from animal sources such as meat, fish, poultry, eggs, and dairy products. Incomplete proteins lack one or more essential amino acids that your body cannot make itself. Incomplete protein usually come from plant based sources such as fruits, vegetables, grains, and nuts. you must eat incomplete sources of protein in a combination that contains all the essential amino acids in order for your body to use them.
As I mentioned, you must get your essential amino acids from your diet because body cannot make them itself. Some of the best animal sources are fish, poultry, lean cuts of meat, and low-fat dairy products. Some of the best vegetable sources are beans, nuts, and whole grains.
Now, I hope that you have a basic understanding of protein and why it is important in your diet. I my next installment I'll explain how much protein you should have in your diet and how to figure out your serving sizes so you can start balancing the foods you eat.

Balance and Moderation the Key to a Healthy Diet
Image via Wikipedia
The key to eating healthy over the long-term is balance and moderation in the foods you consume daily. You can eat any food you desire as long as it is in moderation and balanced with the rest of the foods you consume. For example, I love brownies, so when I have a brownie for dessert, I only have one. I also balance the carbohydrates in the brownie by not having bread with my meal.
The first step in learning balance and moderation in your diet is knowing how to classify foods into their basic source of protein, carbohydrates, and fats and knowing how they are used in your body. The second step is mastering portion. Knowing how many calories you consume from each food source and what your serving sizes are will enable you to balance your meals. Eating this way can be easily incorporated into your lifestyle, it's a plan you can stick with over time.
In my next post I'll show you how foods are classified into their basic components of protein, carbohydrates and fats and how your body uses them.
