I think there is something to be said for a predominantly healthy diet with no restrictions. I don't mean go mad and eat pizza all day - I said predominately healthy, but I mean concentrating on the quality, the macros, and my bodies hunger response rather than the calorie count. MFP and IIFYM has helped me to introduce a lot more poor quality foods into my diet 'as long as it fits' and whilst I enjoy all foods (yep inc pizza) I know that I want to clean up my diet.
Yikes!! Did I say IIFYM and clean eating in the same blog post...
You see I have always believed in clean eating, by that I mean eating clean foods as much as possible. I don't mean the strict 'you can never eat a pop tart again' idea that some people interpret this as. What I mean by eat clean is 'foods that come from the ground of have a mother'!
IIFYM is a great tool and helps to achieve balance in most cases, but doesn't really work for me. I open myself up to choosing the wrong things health-wise on this approach.
I have also been reading the principles of paleo and have taken a couple of learnings away from that too...
