Welcome to SparkPeople!
I know it shows that I’m a newbie as well, but I’ve been a member of this site off and on for years… and it’s still the one and only ‘diet’ I truly trust and believe in.
The best advice I can give you is to utilize this site as much as possible. Read the articles, join a team, use the nutrition and exercise tracker, but most of all, interact with all the other amazing members on this site. If you have a question, ask… I know someone will have an answer and be more than happy to help you.
Best of luck on your journey!
