Abstract

BACKGROUND:

Weight gain is a result of changes in the regulation of short-term meal-to-meal intake. An investigation of the short-term intake and activity levels of weight-gaining persons may provide insight into the nature of the cues signaling weight gain.

OBJECTIVE:

The basic hypothesis was that the investigation of energy balance during periods of dynamic weight gain should provide clues to the regulatory differences that result in obesity.

DESIGN:

The eating behavior and activity levels of 19 weight-gaining men and women and of weight-stable, matched control subjects were compared with the use of 7-d diet diaries. Participants recorded their activity levels, everything that they ate or drank, and the environmental and psychological factors surrounding each eating episode for 7 consecutive days.

RESULTS:

The weight-gaining group ingested 1645 kJ/d more than did the weight-stable group because of a greater consumption of carbohydrate and fat and larger meal sizes.

CONCLUSION:

The greater food intake in the weight-gaining group did not result from environmental, social, or psychological factors, suggesting that the overeating associated with weight gain might be physiologically based.
