Fasting during Ramadan can be deeply meaningful, and the Iftar meal after a day of fasting provides both much-needed nutrition and a chance to gather and celebrate with friends and family. But fasting can also be a challenge to efforts to follow a healthy lifestyle. After fasting all day, many people overdo things in the evening, drinking sugary drinks and eating heavy meals full of fatty and sugary treats. This can leave you feeling tired and sluggish and wondering how you can be gaining weight while fasting daily.
