My people will fail to lose weight, as the gyms are closed. Mosques will be too, tawarih is a good form of exercise too. It will be too dark to run on the roads by the time the food has gone down and dry fasting affects your energy levels.
I'm lucky to have weights and a treadmil at home. So no issues for me.
I would avoid carbs after iftar and go hard on your proteins and healthy fats, eat light for suhur. By doing this, you will avoid weight gain during Ramadan. I'm looking to maintain and bulk after Ramadan to gain mass. In the summer I will cut again.
