Normally when we think about some weight losing activity, we think  about burning calories or sweating off the fat. When you meditate you  have to sit very still, without making a move.  Can meditation,  therefore, be helpful in losing weight?  Although you won't burn  many calories during a typical meditation session, meditation may be one  of the most important practices you will do in your effort to lose  weight.
Weight loss is not just a physical activity. Sure, if you eat less  and you exercise more, you will lose weight.  However, all of our  actions begin in our minds. If you are going to walk for forty five  minutes every day, in order to increase your daily exercise, then you  first have to decide to do it, and at the right time, you have to think  and then go for your walk.  These are all mental activities.
Similarly, if you realize that junk food is only making your  waistline expand, and you want to stop eating it, you first have to make  a decision to change your eating habits and then you have to walk past  and not stop at the doughnut shop on your way to work. Again, these are  mostly mental activities.
If you are trying to lose weight you probably already "know" that you  have to exercise more, and change some of your eating habits. You  "know" this to be a fact, yet you are unable to do it.  All people,  whether fat or slim, have this same dilemma. We "know" many things  intellectually, but we are not always able to put our best intentions  into action.
Meditation is one of the best methods to take control of your own  self. During meditation you will learn how to make your mind stronger. A  weight lifter typically exercises certain muscles, making them stronger  and stronger. Similarly someone who meditates is exercising her  "mental" muscle by directing her mind away from the noise of the world  outside toward the calm within.  Following the meditation  instructions takes a bit of effort, but that effort will be rewarded.
If anyone meditates on a daily basis, she will not only become more  able to concentrate during the meditation session but also more able to  put her good intentions into practice and make positive changes in her  life.
It is not a question of mind over matter, or having to do anything  that you don't want to do. Meditation is an activity that changes you  from the inside out.  Instead of forcing yourself not to eat the  doughnut in between meals, the very desire to eat it will vanish.  Instead of fighting with yourself to go out for a walk, exercise will  become something that you enjoy doing.  If you get into the practice  of meditation, no one will have to twist your arm to make you live a  healthy lifestyle, it will become your natural choice.
Therefore, while you will not sweat off any pounds during your  periods of meditation, the daily practice of meditation could be one of  the most important parts of your effort to lose weight and live a long,  healthy and happy life.
