Abstract
Aim: The body weight is controlled by the balance between energy intake and energy expenditure and also, the amount of exercise-induced weight loss, depends on the amount of the food intake. Milk has also been shown to be more satiating compared to carbohydrate drinks. Therefore the aim of this study was to investigate the effect of milk consumption following exercise on appetite and energy intake in non-athlete females.
Method: Eight healthy non-athlete women (aged 23.25±2.19 years, BMI 21.71±2.42 Kg/m2) volunteered to participate in this study. The Subjects attended the laboratory on three separate randomized trials (there were 3 weeks between trials) during their follicular phase. After consuming a standardized breakfast at 08:00 a.m, 30 minutes continuous exercise was conducted on the cycle ergometer at 65% of the subject’s heart rate reserve. In one trial, the effect of exercise and in the other two trials, the effect of exercise and consuming 600ml of low-fat milk or orange juice (276 Kcal), were investigated on appetite and energy intake. The subject’s energy intake were calculated 60 minutes after exercise or drink ingestion. Also appetite sensations (hunger, fullness, satiety and desire to eat) were assessed using visual analogue scale.
Results: Absolute and relative energy intake were reduced significantly after consuming milk compared with two other trials (exercise,exercise+orange juice)(p<0.05). In addition, consuming milk after exercise in comparison with other trials, caused significant reduction in hunger and desire to eat and it also caused significant increase in fullness and satiety(p<0.05).
Conclusion: The results of this study showed that consuming milk could be useful for controlling the appetite after exercise. Moreover, it could be a part of the strategies for weight control programs.
