Hi,
I would probably ask your chemist or phone lipotrim for advice.
I can see you have just finished week 1, and it best to do little exercise for the first couple of weeks, but you might find in a month or so that you can do the exercise no problem without eating.
After about 6 weeks on lipotrim I was working out everyda, walking my dog everyday, and I felt great, I had lots of energy. Im not sure how intense your exercise is going to be.
If you just want to eat cos your away and you want to then obv the best things to eat are small portions of really lean meat like chicken with no skin or sauce, or white fish, and have some salad - green and white is best like lettuce, scallions, onions, peppers or veg as in brocolli and cauliflower (no mayo or butter or sauces) and avoid carbs big time. Drink plently of water and I would still take your 3 shakes, as the small meal is probably not going to give you everything you need.
I would ask the chemist though, but i know mine would have said that eating a lettuce leaf is a big no no. So they will probably tell you not to eat and not to do anything that is too strenuous.
Hope you have a nice time, I have always wanted to go to centre parks, I am actually going to lough erne golf resort for the last weekend in january, never been and I am really looking forward to going.
