Yeah - I was pretty surprised as I was on a very high fat diet before I started that I didn't get any side effects - a bit of an ache for about 1/2 an hour then going to the loo but nothing substantial, and that was only after I exceeded 25g fat, unknowingly (should stick to under 15g apparently).
What I was surprised about was how much fat is in everything - I know I have been on Atkins so not really paying attention to it, but it was a shock. I thought I had set myself a nice low-fat, low carb dinner the other day and input it on Sparkpeople and realised there was over 40g! I think these 'hidden fats' account for a lot of the side effects people have reported.
With regards to strength, the tablets available without prescription are 60g, whereas normal Xenical (only on prescription in UK) is 120g....so you can see where you could possibly make amendments.....! ;-)
I am not going to make a stand either way for Alli until I have given it a couple of weeks - thanks for the feedback!
