The most important thing to remember to keep an eye on what you are doing - keep a food diary and keep track. Food diaries are very helpful to us, and are not just for calorie counters. Now before you say "But thin Sally doesn't use one, why should I?" -- 'Thin Sally' obviously doesn't have a food problem. Thin Sally probably already eats healthy and in moderation & is probably physically active to boot. Those wanting to lose weight on the other hand DO have a problem and need to work on it. You may not be aware of what you are putting in your mouth.... that popcorn & soda at the movies... the couple of mouthfuls of cheese at the grocery shop stand. You need to put in everything and work from there. If you aren't counting calories or on some specific diet, like Akins/South Beach, or following what a die titian or doctor has given you, then you will need to basically follow the Food Pyramid. If you would like to try something different have a go at following the Asian Food Pyramid, it works on Daily, Weekly & Monthly foods. Both Pyramids work on "Everything in Moderation", and THAT is the key to healthy eating.
