Losing weight can put anyone in a good mood. However, experts are now finding that the kind of diet we go on can determine if that good mood lasts, or if it disappears faster than the pounds.

Many people may find weight-loss success with a low-carbohydrate diet, but until a new study by Australian researcher Grant D. Brinkworth, PhD, and his colleagues, little had been determined about its long-term psychological impact. Out of their 106 overweight volunteers, 55 were placed on a low-carb, high-fat diet, while 51 were place on the opposite combination, low-fat and high-carb. Over the course of a year, weight loss and mood were assessed.

Both groups lost an average of 30 pounds, giving no diet a clear weight-loss advantage. However, mood was a much different story. Although both showed an improvement after eight weeks, only those on the low-fat, high-carb diet experienced a lasting mood boost. Those on the low-carb, high-fat diet returned to their original mood levels.

“This outcome suggests that some aspects of the low-carbohydrate diet may have had detrimental effects on mood that, over the term of one year, negated any positive effects of weight loss,” the researchers wrote in the Archives of Internal Medicine. Although more research is required, the team believes this could be attributed to protein and fat’s effect on serotonin levels and the difficulty of adhering to a structured low-carb plan in social situations.
