I agree, it was a good documentary and well worth trying to find for those who did not see it. To simplify ongoing weightloss, I rationalise the whole thing by believing that going fructose free will allow your body to eventually gravitate to the weight it would have been if you had not been introduced to fructose in the first place.
Simply put, if you weigh 100kg and you lose weight consistently at the rate of 1kg a week, you will disappear within two years. Obviously this will not happen and sooner or later your weight will plateau.
By that time, you should be well adjusted to life without fructose and (as with people who give up nicotine) you will cease to think about it and cease to need it. But, it would not be wise to go back to any regime which allows fructose in; in much the same way that after giving up smoking for a year you would not go back to smoking just 2 fags a day.
I started this journey on the 17th of June last year at almost 108kg, I am now 91kg and seem to be stalled at that weight. But that is fine, I look good, I am healthy and most importantly, I neither diet nor watch my food intake.
So, it is seven months since I ate chocolate, or cake, or snakes or jelly babies or TimTams and I have no desire to try them...and that's the amazing bit.
