If you’re trying to lose weight, you’re probably familiar with the bad rep carbs have. Blamed for helping the body pack on the pounds, several of today’s hottest fad diets are all about minimizing or totally cutting out the intake of carbs.
Beware the hype!
The cardinal rule of any healthy sustainable diet is that it should be balanced and well-rounded, meaning all of the food groups have to be represented. So, don’t go chucking out all of that bread, pasta and rice yet. Labeling all carbs as bad is a sweeping generalization that could have disastrous consequences on your health. Here’s why.
Our body needs carbs. They play a vital role in several body processes such as metabolism, growth and waste elimination. They act as an energy source for power and most importantly, as a fuel for our brain, helping it to function. Carbs preside in a many different types of food, from a humble russet potato to a mouthwatering piece of pecan pie. They even exist in beans, seeds, dairy products and meat to a certain extent.
Define Carbohydrate
Carbohydrates are essentially chains of sugar molecules that, when consumed, are processed by the digestive system and broken down into single sugar molecules that are more easily absorbed into the bloodstream. Each sugar molecule in the blood becomes an energy source which can be expended or stored for later use. The exception to this rule, however, is fibre. Fibre is a carbohydrate but cannot be digested. Rather, it simply passes through the intestines to facilitate waste elimination.
Not including fibre, there are two types of carbs: simple and complex. Each type is defined by the way in which the chain of sugar molecules are formed. Simple carbs, such as table sugar, milk, and fruit, are composed of short chains that are easy to break down by the digestive system. This allows the molecules to enter the bloodstream quickly and strongly, raising the levels of blood sugar. Scientists have found that eating too much food that spikes blood sugar levels is associated with a number of problems, such as diabetes and weight gain (this is probably where the bad rep came from.)
Complex carbs, such as dietary fibre and starches, feature longer and more complicated arrangements of sugar molecules (hence the name). Because of their arrangements, they take longer to break down. In addition, natural sources of complex carbs also have walls formed by cellulose fibre that further decreases the speed at which the carb is broken down. Slower entry into the bloodstream prevents blood sugar levels from spiking, and this has been scientifically linked to weight loss.
Health Canada recommends that carbs constitute about 45-65% of a healthy diet. But not all carbs. People on a diet that promotes weight loss should instead choose the right type of carb.
“Natural” Complex Carbs
That’s right. If you’re on a diet, you’ll take comfort in knowing that eating the right amount of natural, unprocessed sources of complex carbs won’t make you fat. Whole grains, yams, corn and beans aren’t just a bunch of sugar molecules; they satiate your appetite for a longer period of time and tend to have the fibre, minerals, vitamins and nutrients your body needs.

However, some complex carbs, like potatoes, can enter the bloodstream as quickly as sources of simple carbs. As a result, rather than simply opting for complex carbs, dieters should pick and choose according to how fast a carb breaks down and enters the bloodstream. This is determined by the glycemic index (http://www.glycemicindex.com/)
Enjoy that wholegrain piece of toast. Relish that steaming bowl of brown rice. We’ve eaten sources of carbohydrates since the dawn of man. Why stop now, even when you’re trying to lose weight? A diet that’s far more palatable and sustainable than any fad – including natural unprocessed sources of complex carbs with a low glycemic index will not only help you lose weight, it’ll also help you keep it off.
