High sugar / high fat foods e.g. Indian sweets such as Ghulab Jamun, Rasgullay, Balushahi, Baklawa etc are preferably avoided during the Iftar. Milk-based sweets and puddings such as Rasmalai, Barfee etc are preferred. High fat cooked foods such as parhattas, oily curries, greasy pastries are better avoided.
These can be replaced with chapattis made without oil, baked or grilled meat and chicken. It may also be worth avoiding the caffeine content in drinks such as tea, coffee and cola(Caffeine is a diuretic and stimulates faster water loss through urination).
