Hi!
My opinion is to STAY ON PROGRAM! Don't let all your hard work go by the wayside! Remember, it is SO EASY to put it back on (and so FAST too)
As everyone else is saying, for most of us this is not just a "diet" to help get back into shape; It is a program for a life CHANGE.
I am also doing this with few people knowing I am "on a program". I am into my second month now and have lost 16 pounds so far. When we are away from home, I have my oatmeal for breakfast or I make a cup of MF cappuccino (the oatmeal raisin bars are yummy for breakfast too!), then when out with friends at THEIR breakfast, I have coffee or tea and tell them (as someone else did) that I am "not a big breakfast eater and not hungry". No one will even notice if you politely say "no thank you" to things or just tell people you are not hungry! I have never had anyone force feed me (that SHOULD have been my problem! - haha).
L&G for dinner ... just try to watch those oils and butter and no carbs! Have a large salad & try to bring your own packs of MF dressing and use them! You could always put them in a small tupperware type container (or pill jar) before going to the restaurant and no one will know they are MF (if you want to keep this to yourself) Tell people (as Lisa said) that you are trying to be more health conscious with your eating and this is a non fat salad dressing you like!
Most people on vacation are more concerned with what THEY are going to order and eat that with good conversation and a happy, new "thinner, healthier" attitude -- no one will notice what YOU do or do not eat (unless YOU make it the topic of conversation).
Those 'ready to drink' shakes are a blessing too!
Enjoy vacationing with your friends in Vegas!!! I'm sure you'll have a great time!
Come home a winner! AND A LOSER!
