I too only told close friends about the diet as I dont really want everyone knowing but for those who have noticed I have lost weight (hard not to when I've gone from a tight 18 to a baggy 12 lol) I have told them I am healthy eating but cut down on carbs and calories, when they have asked for specifics of my diet I have simply said no bread, pasta, rice, potatoes etc and no junk. You are bound to get the why dont you have salad or a healthy option if out and about, my answer is, I have planned all my meals and consumables and I am not straying from it, what I am doing is working and I dont want to be tempted. so far it has worked and stopped the questions. when it comes to the drinking or lack of when out, do the classic, do you know how many calories are in that? or just simply say alcohol is not part of my diet plan, so i would rather not. hope this helps. good luck
