Which Side is Right?

To be sure, both sides have their points, and plenty of studies have supported arguments for and against diets containing carbohydrates.

Much of the debate focuses on the energy-enhancing characteristics of carbohydrates and how they compare to fat's usefulness as a fuel source. While carbohydrates are an easily usable source of glucose, anti-carbohydrate enthusiasts argue that fat can provide energy just as well, if not better. In addition, they argue that carbohydrate intake has too big of an impact on insulin, which leads to wild swings in energy levels.

Macronutrients Effect on Body Hormones and Aging

One area that doesn't receive much attention, though are the hormonal impacts of carbohydrate and fat intake. Though occasionally people will point to fat's ability to increase testosterone levels as a plus for body composition, the effects of carbohydrates on bodily hormones such as testosterone is rarely discussed. A recent Duke University study published in the Journal of Applied Research indicates that the impact carbohydrates make on hormones is quite significant - and a bit scary. The 3-month study from Duke had participants consume a diet with 60 percent of calories from fat, 20 percent from carbohydrates and 20 percent from protein. The aim of the study was to determine what effect the low level of carbohydrates had on aging process markers: glucose and insulin levels. An increase in glucose and insulin levels is considered a definite sign of aging.

Past studies have shown that inhibiting insulin production and lucose metabolism and increases lifespan in animals, so this study was developed to determine whether sought  those findings corresponded to humans.

According to the results of the Duke University study, low carbohydrate intake can slow the aging process.  The analysis of study participants found that insulin levels dropped by 40 percent, while glucose levels declined by about 10 percent.

The Duke University study findings indicate that the low carbohydrate intake resulted in less stress on the body and a delay of the aging process. Just one more serving of food for thought in the constant carbohydrate debate on health and aging.
