            Are you trying to find an effective diet that will help you shed pounds fast?  If you are, then you have probably considered the famous Atkins diet.  Over the past few years, this low-carbohydrate, high-protein, high-fat diet has become extremely popular with image-conscious Americans.  It has demonstrated to help obese people lose weight quickly by consuming steak, bacon, and other fatty foods (Foster et al., 2003).  Who wouldn’t want to go on this diet?  However, people are so obsessed with losing weight that they often overlook the potentially dangerous side-affects. 

            A group of scientists (Foster et al., 2003) conducted the first randomized trial of a low-carbohydrate, high-protein, high-fat diet compared to a more conventional, high-carbohydrate, low-fat diet in order to test the efficacy as well as the possible consequences of the Atkins diet.  Forty-three obese women and twenty obese men participated in this one-year long study.  Thirty participants were put on the Atkins diet, and the remaining thirty-three were assigned to the conventional diet.

            The results showed that although the subjects on the Atkins diet lost weight more quickly, both groups showed roughly the same amount of weight loss after one year.  Each subject was weighed every 2-6 weeks, and after 3-6 months, the Atkins dieters had lost more weight than the conventional dieters had.  However, after one year, there was no significant difference in weight loss between the two groups.

            The participants in the experiment were also assessed for certain health problems, including coronary heart disease.  One dangerous issue associated with coronary heart disease is cholesterol levels, which were measured in the dieters.  Of the two types of cholesterol (low-density lipoprotein (LDL), the “bad” cholesterol, and high-density lipoproteins (HDL), the “good” cholesterol), high LDL levels are a major risk factor for coronary heart disease (2004).  The results showed that Atkins dieters experienced an increase in their total cholesterol levels: both LDL and HDL went up.  The conventional dieters experienced a decrease in their total cholesterol levels: both LDL and HDL went down.  Foster et al. concluded that from this information it hard to determine which nutritional regimen puts dieters at greater risk for coronary heart disease. 

Another test that was conducted measured the dieters’ triglyceride concentrations.  High triglyceride concentrations are another risk factor for coronary heart disease (2004).  The results revealed that Atkins dieters experienced a decrease in their triglyceride concentration levels (this is good), while the conventional dieters experienced an increase (this is bad) (Foster et al., 2003).  

At this point in time scientists and nutritionalists are unable to confirm which diet is a better and healthier choice.   After one year, the two groups assigned to different diets showed the same amount of weight loss.  However, there are both positive and negative aspects concerning the dieter’s health of both diets.  While the conventional diet proved to lower the “bad” LDL cholesterol levels, it also lessened the “good” HDL cholesterol levels; while the Atkins diet showed an increase in the “bad” LDL cholesterol levels, it also raised the “good” HDL levels.  Additional studies are needed to determine which diet is a better overall choice.  Also recall that this experiment tested the effects of the Atkins diet only on obese people.  As for right now, be aware that there are serious health risks associated with the Atkins diet, and the best way to lose weight safely is by exercising and eating right.
