Calories, Not GI, Count in Diet

February 12, 2008: 12:00 AM EST

In a press release, the United States Potato Board say US and Brazilian researchers found that the glycemic index of a diet is not important. Calories are key to weight loss, they say. The researchers studied 203 overweight and obese women, comparing high and low GI diets, with a large amount of potatoes in the high GI diet. At the end of 18 months, both groups had lost weight and there were no significant differences in weight loss. The US Potato Board says this shows that potatoes should be part of a healthy diet of fruit and vegetables. Another recent US study has shown that the GI does not matter as long as calories are reduced.
