If you have 15 pounds to lose and want to lose it all in two weeks, you’re going to have to adjust your thinking or you’re either going to be very disappointed, or you’ll resort to a really unhealthy method of weight loss and risk making yourself sick.

Yet, if you need to loose weight fast over a period of a few days or a week just to fit into a dress for the weekend, for instance, and you realize that if you drop pounds quickly you’ll likely put them back on after the weekend is over, there are some things you can do to drop a few pounds right away.

When you loose weight fast, you’re losing water weight, not actual fat. So as long as you understand that your quick weight drop is really a very temporary thing that’s easily undone and you don’t risk your health to do it, you could be very pleased with the results.

First, stop drinking anything with calories in it. Just that alone can help you loose weight fast. No alcoholic beverages, no sugar in your coffee, no soda other than diet soda, and no fruit juice or flavored waters that have calories in them. Just this step alone can cut hundred of calories from your day. Replace those sugared beverages with water. Don’t drink 64 oz of water in one sitting—that can even be dangerous—but try to get that much in slowly throughout the day.

If you really want to loose weight fast, you can drastically cut back on your calories. While 1200 calories is really just above a starvation diet, if you limit yourself to that or fewer for only a very short time like a few days, it won’t harm you. We’ve all had those days where we’re sick with the flu or we don’t feel well and we eat very little. It happens from time to time naturally, so doing it on purpose for a short burst won’t hurt you either, just don’t decide to starve yourself as a method for long-term weight loss.

Stick to easily digested foods like vegetable soup with little fat in it. Soup can help you feel more full while you’re eating so little food and take away the growling stomach that will no doubt happen at least a few times if you cut your calories back drastically. Drink seasoned broth, or clear or tomato-based vegetable soups for best results.

Avoid potatoes and starches like corn and peas. Go for broccoli, lettuce, spinach, celery, and other greens. Oranges and strawberries can help your sweet tooth. And take a multivitamin, so you’ll still get important nutrients while you loose weight fast.

Each of these tips will help you loose weight fast. However, you should check with your personal physician to make sure are physically fit enough to loose weight fast.
