Welcome to FOH Duma!
I've really enjoyed following your journal so far! Yes, it is best to write in it every day!! The good, the bad and the ugly! We need to journal the good and bad so we (and others ) can see where some of the issues lie.
Take it from me...it's far too easy as (AK) said...for one day to become 1 week...and then 1 month and then you crumble without any support, but think you can "get back to it when you want to"!...but then you realise that the support you needed was right back here where you found it in the first place, if that makes sense!?
You should be extremely proud of your 4.5kgs weightloss! Do you realise that is 9....yes 9 tubs of margarine!!? 
Be very proud of the great start you have made towards a healthier ,longer life.
See how you go with the meat..but be careful you replace it with enough nutrients and calories from something else.
Have you tried portioning your meat? just take out what you need for one meal and freeze the rest.
Your meat portion should be no bigger than the palm of your hand apparently.
Don't forget the value of drinking plenty of water. You would need at least 2 litres a day. ( your water intake can include green/peppermint/herbals teas...but not coffee!) 
The picnic and "incidental" exercise sounds great.
Yarndley's Bush? I think that is up near Te Kuiti somewhere? I had rellies live there as well as Hamilton & Ngaruawahia and visited them a few times, years ago (fellow Kiwi here
)
Have a good week and keep up the excellent work so far!
Don't over think things too much...you've had a good 2 weeks...now with other small changes, you just have to do it again.
