Low-Carbohydrate Diets May Be Useless For Weight Loss

Losing weight is difficult enough as it is, largely thanks to the omnipresence of sugary treats, snacks, dessert-like coffees, and the sheer and uncompromising deliciousness of cheese, to name just a few gastronomic offenders. Unfortunately, we are also bombarded by the media with a new fad diet seemingly every month, and it’s difficult to determine which one may be the most effective.

One of the most persistent diet trends is the low-carbohydrate diet. The hypothesis behind this is that eating too many carbohydrates drives up the body’s insulin levels, which causes the body to retain fat and suppress burning off calories. The key word here is “hypothesis”, as very little about this diet has been conclusively proven to be true, and a new study in the American Journal of Clinical Nutrition has concluded that this type of diet is almost completely ineffective.

The low-carbohydrate diets generally suggest that you consume the same number of calories you do normally, but replace your carbohydrates, especially if they are refined grains and sugars, with fats or proteins. In order to test this diet's efficacy, the researchers – led by the National Institutes of Health obesity researcher Kevin Hall – managed to find 17 overweight and clinically obese patients that were willing to be confined to a hospital for two months while they were continually monitored by the most cutting-edge health equipment.

For the first month, they were given a diet similar to the one they were having in their normal daily lives, which included plenty of carbohydrates. For the second, they were given a very low-carbohydrate diet that totaled the same amount of calories.

Determining the effectiveness of diets is incredibly difficult, as there are so many additional factors that can affect a person’s ability to burn calories. Do they exercise? What if they spend some days completely sedentary and others running around? What if they don’t stick rigidly to their diet? As a result, many diets are based on nothing more than conjecture and scientific-sounding rhetoric.
