Hello! why not count the calories you have a day for example 1 meal 200 + 3 shakes 402 = 602 calories a day and just tell the truth without revealing the name of the diet..so you can say i am on a very low calorie diet about 600 to 700 calories a day and that would be telling the truth you can also add that you are having 100% of the vitamins and minerals required by taking vitamin pills everyday and that is very very close to the truth without revealing exactly what you are doing . I am suggesting this because i think you are a bit like me and wouldn't be happy lying so this is a truth i would be confortable telling if i didn't want people to know about CD. Hope it helps
