That's always the big problem with me - particularly in the morning. I am not hungry but know I have to eat and take on plenty of liquids to get me through the day. I can eat, pray, sneak a quick hour in bed before getting up for work and not remember what I had to eat for Sahur! Normally a very light breakfast guy so forcing down steak, chips and veggies at 4.00am is quite an effort. However from experience if you have a carbohydrate rich meal early you feel hungrier during the day. Here we tend to break the fast with sugar rich drinks (coconut juice, fresh coconut, syrup and tape(from cassava) and snacks/dates, pray and then have a more normal evening meal.
Got a gym session with personal trainer after Maghrib tomorrow so that should be interesting.
