Refined Carbohydrates – The Enemy Of Weight Loss

Although most dieters have heard that it’s a good idea to avoid carbohydrates (especially sweets, bread, pasta, cereal, etc.) when trying to lose weight, many not understand why carb avoidance is so necessary for losing weight. Even doctors may make the claim that calories are calories and to lose weight all you have to do is eat fewer calories than you burn through your activities. The thing is, hormonal factors can influence how easy or hard calories from a given type of food are to burn. With a little investigation, it becomes obvious that a high intake of carbohydrates, regardless of one’s total calorie intake, will make the body prone to depositing fat.

At the heart of the matter is the hormone insulin. The function of insulin is to stimulate the cells to take up sugar from the bloodstream (when blood sugar is high, as it typically is shortly after eating) and store it for reserve energy.

The surplus of sugar in the bloodstream is initially stored in the tissues of the liver and large muscles in the form of glycogen. Glycogen can be quickly converted back to blood sugar when needed for energy to fuel sudden bursts of activity. The available storage space for glycogen is pretty limited, and when insulin has caused the glycogen storage to be filled up, the remaining excess blood sugar is stored as fat.

There is considerably more storage space in the body for fat than there is for glycogen. There are billions of fat cells in the body, each of which can enlarge to over 100 times it’s original size to accomodate extra fat storage. As an aside, this is why it is possible to get fat again after liposuction – even if you remove many of the body’s fat cells, those that remain can enlarge considerably to store fat.

Insulin is extremely powerful in its fat storage effects. In fact, not only does it stimulate fat storage, high levels of insulin block the effects of the body’s fat burning mechanisms. It is for this reason that minimizing the intake of high-carb foods is so important.

High carbohydrate intake (and it really doesn’t need to be very high) stimulates the release of large quantities of insulin. Large amounts of circulating insulin will strongly inhibit the body from being able to burn fat for a period of 1 to 2 days! To put it another way, simply eating about 20 to 25 grams of carbs at one time, which is about the amount of carbohydrate in just one piece of sliced bread, is enough to totally turn-off your body’s ability to burn fat for up to 48 hours no matter what your diet is and no matter what you do for exercise during that period of time.

Some people mayhave doubts about that last statement as it is certainly possible to eat a lot of carbs and lose weight – for a while anyway. Notice that I said that high carbohydrate intake causes high insulin production that blocks FAT burning. It is still possible to eliminate retained water (which will produce weight loss), and it is still possible to burn calories, but the calories you do burn will not be from fat, they will be from glycogen and your lean body tissue, primarily your large muscles. As you may be aware, lean body tissue (muscle) is highly metabolically active, and if you burn that tissue, ultimately your metabolism will slow down, making it harder and harder to lose weight.

Because of the effects of insulin, minimizing carbohydrate intake is strongly recommended for sustainable fat burning and the most efficient and lasting natural weight loss. Now, not every person will do well to go on the Atkins diet and eat only protein and fat. Excessive protein intake can create its own problems that can ultimately interfere with ongoing weight loss due to detrimental effects on the liver. Instead, the best diet program in most intances involves eating plenty of fresh or frozen vegetables and fruits, nuts, seeds, and moderate quantities of protein from lean meats, fish, eggs, and dairy. The carbohydrates you do consume are best obtained in high-fiber forms from vegetables, fruits, seeds, and nuts, rather than from refined grains.

A few diet plans will recommend a low carbohydrate intake, yet suggest allowing yourself a “reward” of some high-carbohydrate food like a cookie or other sweet as often as once per week. I disagree with this recommendation as it can sabotage your natural weight loss program on two levels. First, as we’ve been discussing, the carbs will trigger a high insulin release which will shut off your ability to burn fat for up to two days. So, at once per week, you could lose as much as 8 days per month of potential fat burning – decreasing the effectiveness of your diet by as much as 25%! The other problem is that eating carbs tends to set you up for carb cravings. At the very least, such cravings will test your will-power, and they could cause you to cheat on your diet repeatedly. This could ultimately doom your diet to total failure. I recommend that you refrain from eating refined carbs except on special occasions (parties, holidays, etc.) and this ideally would be at a frequency of at most, once every 4 to 6 weeks.

Hopefully you now have a better understanding of why high carbohydrate consumption is so damaging to a natural weight loss plan. If you commit to a healthy diet and avoid the carbs for 2 to 3 weeks, you will likely find that you don’t really miss them after that period of time and so avoiding them becomes much easier. With a little extra effort early on, you’ll find that eating a healthy diet becomes natural to you and you’ll be able to reach your long-term weight goals.
