As a recipe for losing weight, taking a slice of chocolate cake at breakfast would seem an unlikely fantasy.

A team from Tel Aviv University found that eating pudding as part of a balanced 600-calorie breakfast that also included proteins and carbohydrates (碳水化合物), could help dieter to lose more weight---and keep it off in the long run.

Attempting to avoid sweets entirely can create a psychological addiction to these same foods in the long term. So adding desserts to breakfast can control craving(渴望) throughout the rest of the day.

Over the course of a 32-week-long study, participants, who added desserts to their breakfast lost about 40 pounds more than a group that avoided such foods. What’s more, they kept off the pounds longer.

A meal in the morning provides energy for the day’s tasks, aids in brain functioning, and kick-starts the body’s metabolism (新陈代谢), making it decisive to weight loss and maintenance. And breakfast is the meal that most successfully regulates ghrelin, the hormone that increases longer. While the level of ghrelin rises before every meals, it is controlled most effectively at breakfast time.

The researchers hoped to determine whether meal time and composition had an impact on weight loss in the short and long term, or whether it was a simple matter of the caloric count.
