Of all the cleansing methods I've looked at, this one seemed the easiest to do. And it turned out to be very effective. You will notice the changes right away.
There are some things that should be noted:
1. If you read and follow the instructions accurately, you will NOT feel hungry, but you WILL have cravings for foods that have sugars, caffeine, etc. There is a difference and some of the negative reviews were from people who cannot distinguish between the two.
2. There IS some measure of discomfort. I could literally feel the toxins leaching through and out of my body. So, do whatever you can to help the expelling though herbal laxatives and the salt cleanse.
3. This is NOT MEANT TO BE A DIET. It has a side benefit of losing weight as the author notes, but as the author also notes it's origins and applications are NOT about losing weight. This is also misunderstood by those giving negative reviews.
4. Read carefully and buy the correct maple syrup. One reviewer suggested that you would consume between 600 and 1200 calories in syrup. That is totally inaccurate - that person was probably consuming syrup with added sugar (a warning also given by the Burroughs). 100% organic grade b maple syrup has 50 calories per 2 tbl serving, which is the ratio for this cleanse. At 6-8 servings per day, that is 300-400 calories.
As with anything, your mileage will vary, but my experience seemed to generally line-up with the book and it's nearly 30-year old concept.
