Everyone wants to be able to dress like their idols Paris Hilton, Lindsay Lohan and Hillary Duff.Weight loss programs, however, can be really expensive. And no amount of saving your monthly allowance will be able to make you afford one. Unless of course you have a trust fund like that of the Hilton sisters!Losing weight however need not be expensive. In fact, you can lose those additional weight and pounds without even having to shell out a lot of money. This is especially true if you do not really need to lose much. You can actually do it for free. You don’t believe me? Read on below and find some tips on how to achieve weight loss for free.Determine how much to loseThe process of losing weight is different for different people. This is because people need to lose different amounts of weight. A weight loss program that has worked for someone who needs to lose a little over 20 pounds may not work for someone who needs to lose more than 50 pounds. The same goes with people who have the time to work out in a gym and those who opt for home exercise. Before you determine the right program for losing weight, you have to first know just how much pounds you have to lose. To do this, consult the body mass index to know the ideal weight for your age and your height. After doing this, you will be able to plan your own weight program.Combine diet and exercise One of the most costly mistakes both financially and health-wise that teenagers make is to concentrate on just one aspect of dieting. This may not be good for the dieter as concentrating on just one will not balance out the weight loss. If you diet too much, your body may suffer from the loss of nutrients and exercising too much may lead to muscle pains and body aches. It is important that you combine both of these things to achieve maximum weight loss. What is more, when both of these are combined, weight loss is more permanent and more lasting.Slowly but surely Crash diets often do not work in the long run. Oh, it can make you lose weight fast but because of what your body has gone through, you will gain the lost pounds just as fast. In addition, crash diets will only put your body and health in jeopardy. It is important that you give yourself enough time to lose those unwanted pounds slowly but surely. This way, you can be sure that your weigh loss will be for keeps. Check your commitment meterOne important ingredient in a weight loss program is the hunger for weight loss. You can enroll in the most expensive weight loss program but without the determination to lose weight, your money will just go down the drain. If you have full commitment in the program, even if it is something that you have only planned yourself, you can succeed.
