I did the accupuncture diet some 6 years ago and I did get results. What they do is stick 2 little needles on the outer of your ear and the inner on the pressure points that can stimulate hunger. Then you follow a really restrictive diet for one week consisting of only protien (ie meat, fish, chicken, eggs etc). You are not allowed any vegies or condaments apart from salt and some spices that are allowed (ie curry etc). You need to test your urine to see if you are in Ketosis. You have to drink at least 2 litres of water a day and take a multi vitamin. I found that I got really hungry, headaches, lethargic etc from it but I did lose 3.4kg in my first week.
The second week is basically incorporating a healthy diet to maintain the weight that you lost the first week, with the exception of no carbs (bread, rice, pasta, potatoe) (you have to gradually bring them back over the coming weeks). So it is like cereal for breakie, fruit for mt, crackers with ham and salad at lunch and a steak and vegies at tea time.
I ended up losing around 12 kilos in 7 weeks, but I believe that you can do it without having the accupuncture part of it - I did not feel that it helped me all but it is worth a try if you are serious about losing!!
Hope that helps
2008 - my year to be great!!
