I have been using Fitday for over 4 months, non-stop. I have tried targetting a certain deficit every day, and I have also tried targetting a certain calorie intake every day.
- Intake targetting makes it easier to establish daily eating routines.
- Deficit targetting keeps my body guessing more, and its probably better for my metabolism.
Both work, it just depends which works better for you.
I have written about it a few times in my blog, so I'll just post a link instead of repeating it:

One thing that has happened since I switched to an intake target is that my rate of weight loss has slowed to less than 1 lb per 3500 calories deficit. So targetting a deficit might have been better for my metabolism. But at the same time, my body fat has gone from 30% down to 11%, so the slower metabolism might just be my body's defense mechanisms kicking in.
