Congratulations on taking action! The simple practices of good nutrition and maintaining normal body weight are two keys to our health over which we have 100% control. And, as a bonus, these two things play a big role in extending the length and quality of our lives.
There are a lot of resources both here in the forum (many discussions on weight-loss and health-related topics)and in the website attached to it (articles, calculators, resource links). Use whatever you need to achieve your goals.
See you around!
