Welcome to FitDay. I think you will find lots of buddies here. All of us have been, or are, in the same boat you are in - believe me. And all of us will attribute our success to honestly logging the food you eat and the activites you do. One of the great things about FitDay is that it allows you to take responsibility for your own success (and occassional failures, if I am being honest) because it gives you the tools to see the good, the bad, and the ugly in our diets.
Try logging your foods as you would "normally" eat for a week or 2. Then use the charts and graphs to take a good hard look at what is going wrong. Too many calories? Work on reducing protion size. Too many carbs - simple sugars and starches? Start replacing them with better choices.
Some of us are on prescribe diets like Atkins, lots of us just try to modify our normal diets to keep them in line with our goals.
Check out the many threads here. Chime in when you have a question or idea. And most of all don't be a stranger. We are all in this together!
