After posting my reply, it made me think of my diet saboteur..
At the start of last year my best friend and I went on Weight Watchers today. We were inseperable, we walked together, then joined the gym together... then later on last year (November-ish) she told me that for the past 6 months she had developed an eating disorder (bingeing and then purging).. Then she went on about how she ate what she wanted now instead of counting 'points' or kilojoules and that it wasn't 'healthy' that I was so 'obsessive' about counting points etc etc.. Now, looking back, at that point I don't think I really was obsessive about it.. I counted my points and that was that.. but she got it into my head that I had a problem with it.. And said to me "I've been eating what I want, just stopping when I'm not hungry any more, and I haven't put on any weight" which started to cause other problems for me, eg me having the mentality that "I can eat what I want as long as I stop when I'm full!". Well, that doesn't work for me. Because I just don't stop when I'm full. And I eat for the sake of eating without points/kilojoule counting to make sure that I'm not eating too much for the day.
So I started eating all sorts of things I wouldn't normally eat, and it just screwed me up completely. I started nibbling and snacking between meals constantly, and that's how I put on about 6 kg's that I had lost... I would have put on way more but since I joined the gym I've religiously gone and worked my butt off. I've only just gotten back on track in the last few months, switching from points-counting to kilojoule-counting. That's been my saviour, just changing the way I do things.
Needless to say, my "best friend" dropped out of going to the gym a few months after we joined, I went the complete opposite way and got addicted and made it my life and my career, and she became a workaholic with no time for me. I haven't seen her since Easter.
She basically made me feel like a freak for being conscious of what I ate.
Sorry this was such a long story, but beware of the best friend - even if she seems to have the same goals, it doesn't always turn out that way... a long friendship went down the drain...
