Hi Jocky, I tend to have 2 or 3 portions of fruit and 3 or 4 portions of veg a day. My favourite fruits are apples, pears and grapes.
I tend to have fruit and nuts, fruit and bacon, or occasionally fruit and chicken for breakfast, a fruit snack, a small salad, a nut snack and a main meal each day, and I've lost 19lbs so far.
At weekends I generally just eat twice, once at about 2pm and again at about 8pm. For some reason that works really well for me, but only at weekends, possibly because I'm more relaxed than at work...
Before you decide that your work colleagues are right, wait and see what actually happens. If you're losing weight, they're full of crap!
