Another thought. If you're covered by health insurance from work, they will more than likely approve you to see a nutritionist (you may need a doctor's referral). I didn't do much research but thought that I was eating correctly. I found out that much of what I thought was good for me wasn't. The nutritionist suggested a diet, actually got me eating smaller portions but more meals per day and suggested myfitnesspal.com (as stated above, an excellent tool).

It's only been a few weeks but I feel great and my clothes are fitting much better. I refuse to weigh myself until my next appointment but I'm confident that the numbers will be very positive.
