To be honest hun, websites probably wouldn't be any good. I've looked at loads and you have to pay to get the info. you need. I've never been but weightwatchers are supposed to good. As you get weighed infront of others every week it would motivate you more to lose weight.
Or just eat healthy foods and not snack between meals. Have a breakfast that's filling (porridge without all the sugar!) have a wholemeal bread sarnie with salad etc in, a yoghurt, fruit etc for lunch & grilled chicken or fish with veg. for dinner. Cut down on your portion sizes too (try a smaller plate)
Try not to eat late at night especially not pasta, potatoes or really startchy foods as they sit heavily on your stomach & are harder to digest causing your body to turn it into fat rather than energy. Drink loads of water throughout the day, its very good for flushing out toxins in your body, increases your metabolism & helps you lose weight.
Its all easier said than done though. Do treat yourself every now & again, don't deprive yourself completely.
Good luck. I've started my diet again today, after doing really well & losing 12lbs I thought 'Oh i've done really well, I can have some chocolate now & crisps & cake & biscuits & ice-cream & cheesecake' (the list goes on!
) so now i've blown it
