The seminars are for persons interested in getting WLS and are set up through a hospital in my area. I speak about several things pertaining to diet, nutrition and exercise as it relates to post-op care. So many people go from one extreme to the other, which takes a toll on the average person who isn't ready for it. WLS has about a 33% true "success" rate, in that 1/3 of the people use it as a tool and get out of it what they hoped. Another third do not lose, or gain a significant amount of weight back after the initial loss, mainly due to emotional and mental issues surrounding the obesity in the first place. The other third are 'successful' per se with the surgery because they lose weight, but find that they are caught in that 'extreme' where they FEAR calories and fear weight gain, so much so that they become the polar opposite and yet the exact same...they're on the opposite end of the spectrum physically, and yet they're damaging themselves just as much by being so malnourished.
To answer your question, I touch on all of the above and give insight on how to live post-op, based on my own experiences. Again, this is why I've said I've personally seen so many people come and go through WLS based on what they 'thought' would happen and utterly fail. Nothing in life is a guarantee...
