Hi Leslie--Welcome to this board. Here you will find lots of support in your weight loss goals--but any information you need to achieve your goals.
First step is finding out where you are so you can start. This link is very helpful in determining your current BMI--and then you can set your goal weight and it tells you how many calories you need to consume a day to achieve those goals.
Another new hIgh tech device that is very helpful if you have a smart phone--I-phone or android is to purchase a Fit Bit or Jawbone UP which tracks you're daily routine for calories burned etc. You can add free calorie/carb apps to sync with these devices making it real easy to track what you're eating doing each day.
Good Luck to you on this journey--just make a plan--stick with it and you'll get there.
