That is always temporary. It's usually 90% water which will be put straight back on as soon as your body rehydrates, which it must do or else you'll suffer severe health problems or die.

Some popular fad diets are not what we call crash diets. These diets have been around for a while and what they try to do is to part you and I from our hard-earned money and make their inventors rich.

Some are good nutrition plans, though. But they cost you money while you can get the information from your doctor for free. Or those plans are too hard to get along with, so many folks give up after a week or two.

Why are fad diets so bad? Read on.

1. If a diet program promises you quick and easy weight loss, it's often based on eating certain types of food. However, consuming only some kinds of food will prevent you from getting a balanced diet.

These programs usually recommend supplements. The problem here is most of the times, the supplements they offer can't be absorbed into the body unless you eat foods that are not allowed by the programs themselves. If you're faithful enough to stick to your diet for several weeks, you may notice some changes, feel tired and weak due to nutritional deficiency.

2. Fad diets are often boring and over restrictive. After the first day or two, you'll not enjoy your meals anymore. You'll then start to crave food constantly and break the diet. You may even feel guilty, thinking it is your fault that you did not lose weight.

3. Most fad diets do not follow recommendations of the American Heart Association and similar bodies. The promoters may argue that you'll just follow the diet for a short time. But if you do not reach your desired weight in that time, then what? You either continue with a plan that is not good for your health, or stop and probably gain back what you've lost.

4. Fad diets, unfortunately, do not include enough consumption of fruits and vegetables in your weight loss plan, nor do they allow you to consume what your body needs.

5. Quick weight loss diets are just a temporary solution and do not help you to make permanent changes to your eating habits. Permanent changes are the only way to maintain your target weight once you reach it.

Yo-yo fad diets only make your weight fluctuate. And in some cases, you may end up gaining more weight than you've lost. The up-and-down weight issue hurts not only your health but also your self-esteem.

Publicity materials probably bring you hopes for a couple of days, but over time you'll come to find out that what they're offering will not last a lifetime. The best way to lose weight is nothing fancy - eat healthy foods without overeating and exercise regularly. Stay away from fad diets if you don't want to waste your time and money.
