Does Weight Loss Without Exercise Make Sense

Of all the articles and ads about weight loss and weight loss products, you will notice that many of them seem to be saying that weight loss without exercise is what they have to offer. They will tell you about some diet pill, or perhaps a diet, which is going to take the weight off without you lifting a finger...other than to unscrew the cap.

So here's the question: Can somone really lose weight simply by adjusting their diet? So many people feel that they do not have the time to exercise, or feel they lack the energy to exercise, or just plain don't want to. It would be great if all they had to do was take some pill or eat some specific diet and the weight would go away, right?
