As Sharon says make or take the sensible choice, i.e healthy cereal, they aare usually in the wee mini cereal boxes so, that is counted or weighed already for you. Often there is a choice of fruit, so you could either take it for your mid morning snack or sit and peel what ever it is slowly and savour it. That way your body wil think it has had loads more to eat than it has. ( the 20 min thing that makes your body think it is satisfied.) Less chance of you taking the cooked brekkie.
You could then ask to see the evening menu ( if it is not already displayed). Plan waht you will choose for your dinner at night. nice healthy chioces again, and look forward to it. You can tehn work out waht you cna have for your lunch, (don't know if you have a working lunch or a lunch break on your own) Remembering you still have your dinner to follow.
hope some of this makes sense. Oh just thought you maybe eat dinner when you arrive at night and breakfast is your last meal at the hotel. Well you will have ben good during the day, so complete a good day with good healthy choices. If you have time before dinner, you coul dgo for a walk, or if it is a hotel with a gym/pool whatever you good go there 1st.
So soryit is all about planning bu tjust think how good you will feel when you have made the effort and have a good week and a good weight loss.
I have found that even tho i am at home the weeks I am organised I usually loose and the weeks that are chaos aare the weeks I PUT ON!!!!!!!!!
So good luck witht eh organisation and don't say oh well I have slipped up this week I have blown it! You probably haven't! Pull it back and get right back on again.
Apologises for the long post - Sharon as usual has said it very well.
