Effects of Ramadan Fasting With Exercise on Cardiometabolic Health

Completed · Not applicable

Conditions studied: Ramadan Fasting, Obesity & Overweight, Aerobic Exercise, Weight Loss

In brief

The goal of this interventional study is to examine the effects of Ramadan diurnal fasting alone and in combination with moderate-intensity aerobic exercise on cardiometabolic health in adults with overweight and obesity. The main questions it aims to answer are: 1. Does Ramadan diurnal fasting lead to changes in body composition and cardiometabolic health outcomes? 2. Does adding moderate-intensity aerobic exercise during Ramadan fasting result in greater improvements in cardiometabolic health compared with fasting alone? Participants will be randomly assigned to one of two groups: Ramadan diurnal fasting only or Ramadan diurnal fasting combined with a supervised moderate-intensity aerobic exercise program. Cardiometabolic, metabolic, and behavioral outcomes will be assessed before Ramadan and during the last week of Ramadan.
