I am very repeatative in my food in general, but at the moment I have a freezer full of things that I'm trying to slowly eat my way through so I can make some more room for other things. I also stock pile things when on sale so I'm working my way through those as well. I'm at uni so it's hard to take things as I commute 2 hrs to get there and I refuse to spend money on crap refectory food. The other thing is I'm single so when I cook I eat that meal for a few days as like I said the freezer is full!
When I put down fruit that means I've had more then likely two bananas, a pear, plums, apples so even though it says one I've had tons at that point, then I will add extra as a snack. I try to eat a decent breakfast when I am home, but that is one day a week otherwise I'm out of the house at 5am to go to work or 6am to go to uni.
I'm going to up my meat intake to see if that helps as that is the only difference that I can see from the first and following weeks. Fingers crossed that is the issue!
