Welcome to 3FC =)
Glad to have you with us!
A brief idea. Forget about calling it a diet. Instead, think of it as changes. Diets are temporary. Changes are ... changes. They're things we aim to do for the rest of our lives.
For example, let's say that you want to increase the number of vegetables and fruits you eat. (A very healthy thing to do!) You go along, and for the first week you do splendidly, but then one day during the second week you are a little short of your goal for the day. You wouldn't just quit and stop trying to add in more fruits and vegetables, you'd say "Oh well" and then go back to adding in more the next day as usual. That's a
change. A permanent one.
That's not to say it doesn't take any effort, but we don't have to crash and burn if we make a little mistake.
You can do this! You might want to join in on some of the daily chat threads around the boards to keep you coming back.
