I also tried taking lecithin with my meals for weight loss, however I had terrible reactions - headaches, feeling sick & tired. It took me awhile to figure out what was causing it. I took about 1T and later reduced to 1tsp 3x a day. Needless to say, I didn't lose any weight!!
I have been taking lecithin three times a day hoping for weight loss but have gained six pounds!!!! I have been exercising and sticking to a healthy diet so this is the only thing I have done differently. Just wanted to let you know and am going to stop and see if the weight loss resumes. Thank you for your wonderful site --- it has helped me in so may ways.
