I like the accountability of virtual group but if you think you can do it alone then why not try it for a month.
Broad overview:
Speed foods: fruit and veg with a few exceptions like potato and banana. You can eat these freely and they should make up a third of your meal and be the first thing you reach for in between meals.
Free foods: lean meat, fish, eggs, pasta, rice, grains, potatoes, certain dairy products mostly fat free, beans & pulses . No need to weigh these and should make up the other 2/3 of your meal. Can be eaten freely and still lose but for better weight loss stick with the speed food or use your syns for snacks.
Every day you get healthy extras that should be eaten as they cover the fibre and calcium but need to be weighed:
2 Healthy 'a' a day for calcium include measured portions of milk and or cheese
1 healthy 'b' a day for fibre include measured portions of cereal, bread, nuts and seeds and canned fruit.
Then you have syns each day - usually 10-15 which are pretty much everything else. So your treats, extra portions of cheese, cereal and bread for example.
If you just start off with good wholesome meals made with lean meat or fish, beans and pulses etc with plenty of fresh veg and snack on the same you'll be off to a great start. Once you get the hang of it you can start experimenting with things like making a lasagne and using your syns for the flour and butter or having the odd glass of wine etc.
Hope that helps
