Forgetting Fitness
Many dieters think that just cutting back on calories will lead to lifelong weight loss. This works initially, but only for a while and often leads to yo-yo dieting. Studies show that most people who successfully lose weight and keep it off long-term do so by both cutting calories and adding regular exercise to their lives. Couch potatoes take heart: just 2,000 steps a day will go a long way toward keeping off unwanted pounds. Get a pedometer and get going!

For myself personally I don't even believe in diets, nor does my doctor. I DO eat very healthfully and have changed my eating habits. I don't eat much processed stuff, and eat lots of fruits and veggies, along with protein, etc., and try to stick around 1800 calories a day or so... but I do NOT log them and I eat stuff like peanut butter and cream cheese in small amounts on my breakfast WASA bread, etc. I don't eat junk food at all... but again that is just a healthful lifestyle change and NOT a diet.

And yes I focus a lot on exercise. For me it is working! Not only weight loss but I feel great and my lab reports all came back right where they should be!

Hey, if you can stick to an exercise regimen you are really on the right track! Go for it! Exercise really DOES make a huge difference. Also I would "guess" that as you get into the exercise thing and begin to see a real difference, you will start WANTING to eat right too because you will so much enjoy becoming healthier and fitter. :)
