hi hun! welcome and good luck!
beyonce eh, fantastic!
ok so two choices for you, if you eat something on your first week, you are heading for a disaster. this diet require NO FOOD and tons of willpower. if you can manage that its the magical weight loss wand we've all been looking for.
my advice, go with your friend, have a black coffee or black tea or just stick to water, you'll be sooo proud of yourself afterwards and if you have your shake just before you go, you probably wont want anything anyway.
OR
if you really think you can't do it without having a meal, wait until after the concert to start Lipotrim. be warned tho, these events keep popping up when you're on your LT journey, you have to learn to overcome them, not avoid them, but deal with it.
so many of us have been to concerts, theatre, cinema, weddings, christenings etc without eating a morsel so it can be done!!
just keep thinking of beyonce's body and is that salad worth it! lol!
