I stand in the pool up to my neck. Pool is approx 28degrees. 3 times per week for 1 hour. My body burns calories in creating heat. I am not cold, just a little cool.This is my 4th week and I have lost 5lb.I have not changed my diet except to cut out the rubbish (that is coke and large amounts of chocolate coated licorice.) I have eaten chips, kermonds hamburgers, chocolate thickshake a couple of times.I was thinking of having the lapband done but not now after hearing the horror stories. This pool thing is my last hope and thank goodness it is working.
