Primary Outcome Measures

Name	Time	Method
Effects of a low-carbohydrate diet combined with HIIT or MICT on anxiety levels in individuals with overweight and obesity measured using the General Anxiety Disorder Scale (GAD-7) at baseline and after the last training session at each week (i.e., at week 1, 2, 3, 4)

Secondary Outcome Measures

Name	Time	Method
The following secondary outcome measures evaluating the effects of a low-carbohydrate diet combined with HIIT or MICT in individuals with overweight and obesity are assessed at baseline and three days after the intervention:<br>1. Eating behaviour measured using The Dutch Eating Behavior Questionnaire (DEBQ) <br>2. Cardiorespiratory fitness measured using the maximal oxygen uptake (VO2 max)
