Louisedan - sorry about the gain. There has to be something strange going on! Here are a few observations to provoke some thought.
You mentioned a take-away at the weekend. I find that if I have a take-away it basically undoes all the good work I've done during the week. It doesn't matter what sort of take-away, they all just have too much fat and it always wrecks what has otherwise been a good week. I put on ½ lb this week because of a Chinese (meal that is not a person!).
Do you use your syns every day or accumulate some to take into account for a weekend splurge? A few people can get away with doing this, many others can't. If you don't have enough syns each day this can totally wreck the balance of the plan. I'm definitley in the
can't save camp.
I've just had a look through all your food again and two things have jumped out at me.
1. You do seem to be have had a few meals (eg kebab, curries) that are high in fats which equates to high in syns. I know you are counting the syns for them but on the days you are having them you go way over the maximum 15 allowed (so presumably skimping on the other days).
2. Bananas - the fruit that is not you
LOL.
Whilst they are free the big problem with them is that they are seriously high in complex carbs - ie sugars. Now that's great if you're an athlete and need a quick energy hit to keep you going (look at what the tennis players eat during a game). But if you aren't using them to boost your energy whilst exercising then they're very quickly converted to fat which gets retained by the body. Try going for superspeed fruits instead (eg melon and berries) - this really helps me.
And finally, how close to target are you? If you're not that far off then it may be you need to cut back on syns.
This all sounds a bit negative - I don't mean it to be - but it may help you have a think about what might be the cause of the gains.
