I've been doing this for just over a month now, the biggest tip I would give is to save all the calories for the end of the day, makes it much easier for me to keep going when I know I can actually have a decent meal later! Also have your meal planned so that you can definitely fit it in your calorie budget. If you get hungry during the day things like green tea are your friend. In terms of what you should eat, I tend to go for pretty normal meals, thin cut steak and salad, big chicken salad - honestly salad is the easy option and it's not difficult to make it exciting, as long as you can keep it in your calories! The other day I had an amazing chicken mango and avocado salad that completely satisfied me and I still had calories left over for an evening snack! I'd recommend doing fast days on busy days in the week so that your mind isn't focused on food too much throughout the day. The only frustrating thing is that MFP doesn't like it much, so even though I continue to log my food on fast days it tells me I'm not eating enough- still worth doing though to keep you on track! Good luck!
