I eat really well, but then blow it with bisucits and stuff at night - any ideas how to cut down on the night time snacking?

Check how much you're eating through the day - a lot of people try to cut down, are good all day, then are just too hungry in the evening, and end up snacking.

When i have the urge to snack i drink a cup of green tea.  it curbs the appetite and is really good for you.

i set myself a curfew, nothing after 8 o clock.  it works pretty well.

sometimes the simplest ideas are the best - i only buy biscuits and stuff on the weekend, so don't have them around during the week.
