title: Exercise in dietary restrained women: no effect on energy intake but change in hedonic ratings.
abstract: OBJECTIVE
  To investigate the short-term effects (one day) of exercise and diet composition on appetite control in restrained females.
  
  
  METHODS
  2x2 repeated measures design, with exercise and lunch type used as the repeated factors.
  
  
  METHODS
  The Human Appetite Research Unit at Leeds University Psychology Department.
  
  
  METHODS
  Twelve dietary restrained females, normal weight and regular exercisers
  
  
  METHODS
  A control (rest) and a bout of high intensity exercise (cycling 50 min., 70% VO2 max.) was followed by a free-selection lunch comprising high-fat (HF) or low-fat (LF) foods. Hunger and heart rate profiles were tracked. Energy Intake (EI) was monitored in the laboratory throughout the day. Post-meal hedonic ratings were completed after lunch and dinner.
  
  
  RESULTS
  There was a significant effect of lunch type (HF vs LF) on EI following exercise and rest (P < 0.001) and on total 24 h EI (P < 0.05): EI increased during both HF conditions compared to the LF. A main effect of exercise on tastiness and pleasantness (P < 0.05) of the LF foods served at lunch was found. However, there was no effect of exercise on hunger, weight or energy value of food eaten.
  
  
  CONCLUSIONS
  Exercise raises the perceived pleasantness of foods in dietary restrained women, but does not increase the drive to eat within 8 h of the cessation of exercise. The combination of physical activity and a low-fat diet could be used advantageously to control appetite, prevent overconsumption and protect against the development of obesity.
