Lifestyle changes

i've hinted before to some health issues i have. i've seen a doctor this week for it, and he's asked me to do some changes in my lifestyle. nothing major, but still hard for me to implement. i know my Filofax could help me with that, but i don't really know how. would you guys please help?

so first, i need to change my diet. i have to reduce my consumption of dairy and carbs (all kind), not totally cut them out though, but have one portion a day TOPS. and i have to up my protein consumption.
then i have new rules: i have daily exercises to do, i need to work out regularly, and work on relaxation.

how could i use my Filofax for it?
i thought about different ways to keep track of these changes:

-writing a checklist at the bottom of every day's block, and check when i have had my protein, when i did my exercises, etc.

-write in red when i've eaten dairy/carbs so i now not to eat it anymore for a few days,

-i could have a list of foods i like that are within the new limitations, to help me when shopping

-i could have one checklist and erase it/move it from day to day (maybe using a flyleaf?)

-i should maybe keep track of these things in a different calendar ? (but keep the list of foods i can have in my one life/one binder one ?)

what do you think? do you do something similar, and how? i need the system to really help me reach my goals without it being hard to maintain... the hardest days so far have been when i'm out with family/friends.
waiting on your suggestions you guys :) thanks for your help!!
