You'll be glad to know this site really does help
I joined about 2 weeks ago, but didn't really take it seriously until January first.
So far I've lost 3 lbs (Not bad for 9 days work).
I strongly advise you to fill out the goal, food and activity logs daily and be honest... I've had to add a lot of custom foods but it's worth adding things if you eat them regularly and they aren't on here. It's amazing how you can reduce your calorie intake just by being aware of what you are eating.
Some days it might seem like a right pain to fill it in - but just remind yourself that you took the time to set a goal and you aren't a quitter, so just get on with it and fill it in.
Hope this site works for you.
