I think that the Bernstein Diet has a lot of postives to it. I've been on it numerous times and have never completely finished the plan. I always felt fantastic when I've done it (numerous times over the past 30 years) but have never gone through to the maintenance plan (which I think is very important). I know countless people who have done this diet and never kept the weight off so this is a plan which must be monitored closely when you have completed. Keep to the plan during the week and perhaps treat yourself on the weekend.
As far as the nurses go - I've heard many tales of rudeness and signing contracts - but have never experienced that personally. You just keep your diary and write down everything you eat. Everything! If you're not losing weight there is a reason for it. I used to have a big 8 oz steak every Friday night and still lost weight.
I was never hungry and felt fabulous so I would encourage you to try it but only if you have more than 40 pounds or more to lose. Average weight loss is 4 pounds a week and believe me that the weight just falls off. I have no idea why. I've tried the diet myself without the shots and even gave myself B12 shots but it just wasn't the same. It just comes off the middle and it's wonderful. I think there must be something else in the shots besides B12 and B6.
Everyone has their own personal experience but I can say that if I had the money now, I would do it again in a heartbeat. I believe the cost is now about 160.00 (cdn) per week. The last time I was on (2 yrs ago) it was 140.00.
Best of luck to you!
