I haven't but that is because my personal trainer is able to give me all the info i need at the moment. I train with him twice a week and we discuss foods etc. I keep a food diary and he tells me how I'm doing. I can see now the kind of choices I need to make etc. Plus I train with him obviously. I've been seeing him since March and have only lost 7Kg (had lost 8 but put 1 back on) due to numerous injuries including one that put me "on the bench" for a period of time. We had to switch gears from weight loss to rehab otherwise I'd have lost a lot more by now.
