Fast weight loss is really not that difficult. What's difficult is keeping the weight off. In fact, most people gain the weight back with as much speed as they lose it in the first place. Never-the-less, if fast weight loss is what you're looking for, here's how to do it.

In order to lose weight fast, nutrients, calories, calorie expenditure and fluid intake all must be manipulated.

1. Limit carbohydrate intake to approximately 50g a day. That's not a whole lot. Limiting carbohydrates will drop the water weight quickly because of its diuretic affects. Expect to lose quite a bit of weight from this one tip alone. Fruits and vegetables are the carbs that should be eaten. (More carbohydrates should be eaten on the days you work out.)

2. Flush your body with lots of water. Women sometimes mistakenly believe that drinking water will cause water bloat. In reality the opposite is true. When you limit water intake the body tries to hold onto it. That's because our body's main function is to keep you alive. Drink up to 2 gallons of water a day and you'll flush out the excess water.

3. Increase protein intake. Study after study shows that eating a higher ratio of protein to carbs helps the body lose body fat easier. Protein will boost the metabolism and increases satiety. Protein should be eaten at every meal.

4. Give strength training a try. If you already train with weights, ramp it up a notch. Training with weights is one of the best ways to burn fat. Having more muscle gives you a huge metabolic boost. That's why bodybuilders are so efficient at burning fat.

Unfortunately many women train with weights that are too light. Pick a weight that allows you to do between 8-12 reps, but don't go to complete failure where you can't do another rep. Stop a couple of reps before you reach that point. Training with weights is one of the best things you can do to lose fat.

5. Do high intensity interval training (HIIT). Have you ever seen a fat speed skater or sprinter? Probably not. Compare the physiques of sprinters versus marathon runners. Notice how much more muscular sprinters are. Although marathon runners look skinny, often times they carry around double digit body fat percentages.

Here's how you do it. Warm up for a couple of minutes on a treadmill or your favorite aerobic machine. Sprint for 30 seconds at 80-90 percent of max effort. Rest for 30 - 60 seconds. Repeat 8-10 times. That's it. Let me warn you though. This type of training is very hard to do, but the reward is the amount of fat you could lose, which may be worth the effort.

These are 5 surefire ways to lose fat fast. Follow them and you'll be rewarded with a sleek and trim body.
