If you have only 2 weeks in order to lose some weight you must be wondering how much you can lose in that time period. Of course, the results will be different for each person, as each of us is built differently genetically.
Another factor which has a bearing on your weight loss in 2 weeks is your current weight or, more accurately, the number of excess pounds you have. It's no secret that the more you have to lose to begin with, the faster you will lose it. Therefore, if you have just 15 pounds to drop, your weight loss in two weeks will probably be less than that of a person with 75 pounds to shed.
Your weight loss in 2 weeks is mostly dependent on what you're willing to do for it. It's possible to lose as much as 20 pounds in that time period, although it may require you to use a rather strict diet. Unless you have a big event coming up, I suggest you choose a comfortable diet you can stick to even after these 2 weeks are over.
By using a sensible, comfortable, yet effective diet, you can lose up to 10 pounds in 2 weeks. One such diet is the Fat Loss 4 Idiots diet (which provides a link to about the below) which is a very simple to do diet, does not starve you at all, allows you to choose a great deal of your menu, and provides a swift fat loss rate. You will need to be determined and to stick to the diet completely in order to lose 10 pounds in 2 weeks. A more average weight loss in 2 weeks with this diet is 7-8 pounds.
You can also choose to increase your physical activity level and to cut down your calorie intake without following any specific diet. If you choose this course, you will likely lose around 4 pound in two weeks, though that of course depends on how much exercising you do.
Whatever you do, remember that there is a long future after these 2 weeks. Choose a diet which will help you remain thin and healthy in the long run.
