The average American diet, heavy in animal products, requires the production of an extra ton and a half of greenhouse gases compared to a plant based diet.1 A diet rich in whole grains, vegetables, fruit and legumes is environmentally responsible and can help maintain a healthy weight.
In recent years, however many diet books have blamed plant foods, which are high in carbohydrates for the obesity crisis. While the theory persists, health care professionals have advised against low-carbohydrate diets for years.
A study in the Journal of the American Dietetic Association found that consuming a low-carbohydrate diet (less than 47 percent of calories from carbohydrates) is associated with a greater likelihood of being overweight or obese.2 The July 2009 study found that the lowest risk may be in consuming a diet with 47 to 64 percent of calories from carbohydrates. This was not the first study with these findings.
