Background: In this study, the effect of recently popular intermittent fasting on weight loss and the role of

exercise combined with intermittent fasting on some physiological parameters were investigated.

Aim: This study was conducted to investigate the effect of intermittent fasting combined with exercise and

intermittent fasting alone on some physiological parameters.

Methods: A total of 36 healthy individuals between 20 and 24 years of age, including 18 in the experimental

group (exercising) and 18 in the control group (non-exercising), who were assigned by the random selection

method, participated in the study. The individuals in the experimental group exercised 36 minutes a day, 5 days a

week, along with intermittent fasting for 30 days. On the other hand, the control group did not exercise during this

period.

Results: When the within-group pre-test and post-test physiological parameter values were compared, a

significant difference was found in all values of the experimental group (p<0.05). Similarly, a significant difference

was found in the physiological parameter values of the control group (p<0.05) too, with the exception of body

mass index and body fluid ratio. A statistically significant difference was found between the two groups in terms of

the mean differences between the pre-test and post-test physiological parameter values (p < 0.05).

Conclusion: Based on the findings, it could be concluded that intermittent fasting is an effective method for losing

weight and reducing body fat and that adding low-intensity exercise to this routine ensures more effective weight

reduction. Hence, starving for a certain period of time has a favorable effect on the physiological parameters, and

the practice of exercising in addition to dieting further improves these values.
