A Low Fat Diet May Improve Your Mood

By: June Chen, MD


Whether they are following a low fat diet or a very low carbohydrate diet, it seems that obese or overweight people lose about the same amount of weight after year. But, according to a study published in the November 9, 2009 issue of Archives of Internal Medicine, those people who ate a low fat diet experienced greater improvement in mood.

In this study, 106 obese and overweight adults with an average age of 50 years were randomly assigned to either a high carbohydrate, low fat diet or a very low carbohydrate, high fat diet for 1 year. By the end of the year, the average weight loss for the low fat diet and very low carbohydrate diet was no significantly different. However, the participants in the low fat diet group had greater improvements in their psychological mood.

The researchers suggested that a very low carbohydrate diet might be harder to follow than a low fat diet over a long period of time, especially because it is so far removed from the typical Western diet. One limitation of this study was that it did not actually give details on what was included in the low fat diet or the very low carbohydrate diet, so it may be difficult for nutritionists, dietitians, or physicians to advise their obese and overweight patients on how to eat for mood improvement.
