When we make a conscious decision to change our eating habits we are beginning a diet to lose weight. Sometimes we may have health issues, such as high cholesterol, which is what leads us to eat healthier. Far too many times we diet to lose weight because of some eminent health issues that force our hand. It's a shame that we let things get that far.

It is possible to just exercise and lose weight, but sooner or later the person will not lose any more weight without changing eating habits as well.
A majority of the time it is just the opposite; people diet, that is they count carbohydrates, fat grams, or calories, somehow limiting their food intake to reach weight loss goals.

Any credible source will tell you that a sound weight loss plan will include exercise along with a healthy, smart diet, yet not everyone does this right away. Of course, it is ideal to diet and exercise from the beginning of a diet plan, some people may feel overwhelmed by taking on too much change at once, if exercise has not been a part of their life.
