The Truth About Carbohydrates
Not all Carbs are Created Equal
-- By Becky Hand, Licensed & Registered Dietitian
It’s true. A carbohydrate-rich diet can inflate appetite and girth. Low-carb diets do promote short-term weight loss, but are accompanied by some severe dangers. So what should you do? The truth is, you can have your carbs and eat them too—you just have to know how to choose them.

The Truth about Carbohydrates
Carbohydrates are the body's ideal fuel for most functions. They supply the body with the energy needed for the muscles, brain and central nervous system. In fact, the human brain depends exclusively on carbohydrates for its energy.
Carbohydrates are found in fruits, vegetables, beans, dairy products, foods made from grain products, and sweeteners such as sugar, honey, molasses, and corn syrup.
The body converts digestible (non-fiber) carbohydrates into glucose, which our cells use as fuel. Some carbs (simple) break down quickly into glucose while others (complex) are slowly broken down and enter the bloodstream more gradually.
During digestion, all carbohydrates are broken down into glucose before they can enter the bloodstream where insulin helps the glucose enter the body’s cells. Some glucose is stored as glycogen in the liver and muscles for future use, like fueling a workout. If there is extra glucose, the body will store it as fat.
All carbohydrates are not created equal.
There are basically three types of carbohydrates:

Simple carbohydrates are composed of 1 or 2 sugar units that are broken down and digested quickly.

Recent research has shown that certain simple carbohydrate foods can cause extreme surges in blood sugar levels, which also increases insulin release. This can elevate appetite and the risk of excess fat storage.


Complex carbohydrates (also referred to as starch) are made up of many sugar units and are found in both natural (brown rice) and refined (white bread) form. They are structurally more complex and take longer to be broken down and digested.

Complex carbohydrate foods have been shown to enter the blood stream gradually and trigger only a moderate rise in insulin levels, which stabilizes appetite and results in fewer carbohydrates that are stored as fat. Unrefined or ‘whole grain’ carbohydrates found in products like brown rice, whole wheat pasta and bran cereals are digested slowly. They contain vitamins, minerals and fiber which promote health. Fiber and nutrient-rich vegetables, fruits and beans which are carbohydrates also have many important functions for the body and are important for good health.


Indigestible carbohydrates are also called fiber. The body is unable to breakdown fiber into small enough units for absorption. It is therefore not an energy source for the body but does promote health in many other ways.
Simple carbs, complex carbs, and fiber are found in many foods. Some provide important nutrients that promote health while others simply provide calories that promote girth.


Sugar, syrup, candy, honey, jams, jelly, molasses, and soft drinks contain simple carbohydrates and little if any nutrients.
Fruits contain primarily simple carbohydrate but also valuable vitamins, minerals, fiber, and water.
Vegetables contain varying amounts of simple and complex carbohydrates, vitamins, minerals, fiber, and water.
Legumes such as beans, peas, lentils and soybeans contain complex carbohydrates, fiber, vitamins, minerals, and protein.
Milk products contain simple carbohydrates along with protein, calcium and other nutrients.
Grain products contain complex carbohydrates, fiber, vitamins, minerals, and protein. The amounts vary depending on the type of grain used and the amount of processing. Selecting whole grain options whenever possible is recommended.
What You Should Know About Low-Carbohydrate Diets
Following an extremely low-carbohydrate diet is disastrous, dangerous, and above all—boring! Carbohydrates are NOT the enemy. Including the appropriate amounts and types of carbohydrate-rich foods in your diet is essential for long-term health and weight loss/maintenance.

The Body’s Immediate Reaction to Very Low Carbohydrate Diets
When there is a severe deficit of carbohydrates, the body has several immediate reactions:

With no glucose available for energy, the body starts using protein from food for energy. Therefore this protein is no longer available for more important functions, such as making new cells, tissues, enzymes, hormones, and antibodies and the regulation of fluid balance.
When carbohydrates are lacking, the body cannot burn fat in the correct way. Normally carbs combine with fat fragments to be used as energy. When carbs are not available, there is an incomplete breakdown of fat that produces a by-product called ketones. These ketones accumulate in the blood and in the urine causing ketosis, which is an abnormal state. Ketosis does cause a decrease in appetite because it's one of the body's protection mechanisms. It's an advantage to someone in a famine (which the body thinks it's experiencing) to lack an appetite because the search for food would be a waste of time and additional energy.
Due to the lack of energy and the accumulation of ketones, low-carb diets are often accompanied by nausea, headaches, dizziness, fatigue, bad breath, and dehydration.
Because of dehydration and a lack of fiber, constipation can result.
Exercise and fitness performance is reduced on a low-carb diet. Do not be surprised if your energy level is so low that you cannot make it through your normal workout routine.
The Long-Term Effects of Low Carbohydrate Diets
When you severely restrict carbohydrates, your consumption of protein and fat increases, which has several long-term effects:

The risk of many cancers increases when fruits, vegetables, whole grain products, and beans are eliminated from the diet.
Protein foods are also high in purines, which are broken down into uric acid. Elevated levels of uric acid in the blood may lead to needle-like uric acid crystals in joints, causing gout.
Kidney stones are more likely to form on high protein, ketosis-producing diets.
Over time, high protein diets can cause a loss of calcium and lead to osteoporosis.
The risk of heart disease is greatly increased on a low-carb diet that is high in protein, cholesterol, fat, and saturated fat. A temporary reduction in cholesterol levels may be experienced, but this is common with any weight loss.
The Million Dollar Question
How do you include carbohydrates in you diet in a safe, effective, and controlled way? The “Please KISS Me” (Please Keep It So Simple for Me) plan for carbohydrate control is a wonderful tool that only contains 3 simple rules:

    Great article! I did Atkins about 6 years ago and I've never felt so sick. I even missed like 6 days of work duing the 5 months I was on it. I was losing weight so I kept trying to stay on it though. It messed up a lot of stuff for me - we thought I was pregnant for a few days! BTW - as soon as I quit, all the weight came back.

    I found this article as well. I'm not sure I would go eat a bunch of potatoes and bananas just yet (I don't have anything against potatoes or bananas), but interesting all the same:

    Why carbs are the new diet craze
    Pass the potatoes! Here’s how carbs can actually help you slim down

    Potatoes get a bad rap as little more than a waist-thickening waste of calories. But amazing new research puts spuds squarely at the center of the latest weight-loss buzz, along with other unfairly maligned carbs such as corn and rice.

    The reason: All these foods contain resistant starch, a unique kind of fiber you’ll be hearing a lot more about. In fact, experts agree that it’s one of the most exciting nutrition breakthroughs they’ve seen in years. “Resistant starch has the potential to become the next hot nutrition trend,” says Leslie Bonci, R.D., author of the “American Dietetic Association’s Guide to Better Digestion.” Indeed, more than 160 studies have examined this little-known nutrient’s remarkable health and weight-loss benefits.

    Resistant starch: The new power nutrient
    Although this may be the first you’ve heard of resistant starch, it’s likely been a part of your diet most of your life. Resistant starch is a type of dietary fiber naturally found in many carbohydrate-rich foods such as potatoes, grains and beans, particularly when these foods are cooled. It gets its name because it “resists” digestion in the body, and though this is true of many types of fiber, what makes resistant starch so special is the powerful impact it has on weight loss and overall health.

    As a dieter’s tool it can’t be beat: Not only does it increase your body’s ability to burn fat, but it also fills you up and reduces overall hunger. Its health benefits are truly impressive as well. Studies show it improves blood sugar control, boosts immunity, and may even reduce your cancer risk.

    Resistant starch is bulky, so it takes up space in your digestive system. And because you can’t digest or absorb it, the starch never enters your bloodstream. That means it bypasses the fate of most carbohydrates, which get socked away as body fat when you eat more than you can burn. Here are two more key ways resistant starch can help you drop unwanted pounds:

    It ups your calorie burn
    Unlike some types of fiber, resistant starch gets fermented when it reaches the large intestine. This process creates beneficial fatty acids, including one called butyrate, which may block the body’s ability to burn carbohydrates. “This can prevent the liver from using carbs as fuel and, instead, stored body fat and recently consumed fat are burned,” explains Janine Higgins, Ph.D., nutrition research director for the University of Colorado’s Adult and Pediatric General Clinical Research Center. In your body, carbohydrates are the preferred source of fuel, like gasoline that powers your car’s engine. Butyrate essentially prevents some of the gas from getting into the tank, and your cells turn to fat as an alternative. One study found that replacing just 5.4 percent of total carbohydrate intake with resistant starch created a 20 to 30 percent increase in fat burning after a meal.

    It shuts down hunger hormones
    Animal studies have found that resistant starch prompts the body to pump out more satiety-inducing hormones. A meal with resistant starch triggers a hormonal response to shut off hunger, so you eat less. Research shows that you don’t reap this benefit from other sources of fiber.

    Fighting disease, one potato at a time
    The research on resistant starch doesn’t stop at weight loss. This powerful nutrient is also earning accolades as a major disease fighter from standard bearers such as the World Health Organization. Here’s why scientists around the globe are so excited about its health benefits:

    It can prevent cancer
    Research shows that the butyrate created by resistant starch may protect the lining of the colon, making it less vulnerable to the DNA damage that triggers diseases, such as colon cancer. It can also create a pH drop inside the colon, which boosts the absorption of calcium and blocks the absorption of cancer-causing substances.

    It may fight diabetes and heart disease
    Like other fibers, resistant starch helps control blood sugar levels. “Because it skips routine digestion, we see lower blood sugar and insulin levels following a resistant starch-rich meal,” says Christine Gerbstadt, M.D., R.D., C.D.E., spokesperson for the American Dietetic Association. Blood sugar control translates into more energy and sustained energy. It also means long-term heart protection, because chronic high levels of blood sugar and insulin cause delicate arteries to become clogged and harden.

    It boosts your immune system
    “When you have low levels of good-for-you bacteria in your digestive system, it’s very difficult to fight off disease,” says Joanne Slavin, Ph.D., R.D., a nutrition professor at the University of Minnesota. Resistant starch may boost the growth of probiotics, the same kind of healthy bacteria found in yogurt that keep bad bacteria in check.

    How to eat enough
    Right now, there is no specific target for resistant starch intake. But preliminary data shows that the average American woman consumes about 4 grams of resistant starch each day. Experts such as Gerbstadt believe the research is strong enough to advocate doubling that.

    Adding just ½ to 1 cup of cooled resistant starch-rich food per day can do the trick. See “6 Best Fat-Burning Foods” (next page) for ideas, and follow this advice to maximize your intake.

    Keep it cool
    In cooked starchy foods, resistant starch is created during cooling. Cooking triggers starch to absorb water and swell, and as it slowly cools, portions of the starch become crystallized into the form that resists digestion. Cooling either at room temperature or in the refrigerator will raise resistant starch levels. Just don’t reheat. That breaks up the crystals, causing resistant starch levels to plummet.

    Look for fortified foods
    A growing number of commercial foods have been bolstered with Hi-maize, the brand name of a resistant starch powder made from corn. You can use it in baking (and lower calories) by replacing up to one-quarter of traditional flour in any recipe without affecting taste or texture (King Arthur Hi-maize Natural Fiber, $5.95 per 12-ounce bag; kingarthurflour.com). Or, look for packaged products that include Hi-maize as another easy way to boost your intake.
