Myth: 

Losing weight is always extremely difficult.

Losing weight itself is not always the problem — losing the right weight and keeping it off is the challenge.

Fact: 75% or more of all dieters regain the weight they lost within 1-3 years of completing a diet.

Constant fluctuation of weight is not only demoralizing, but it can lead to increased risk of heart and gall bladder disease.

Another factor that tries patience is rate of weight loss. 1-2 pounds per week is reasonable, and attainable. More importantly, you are much more likely to be able to keep it off.

What is the difference between the "right" and "wrong" weight to lose?

First, some of the body weight you lose initially will be water weight. After that, there are only two real areas from which you will see losses:

1. Muscle mass
2. Storage fat

If you lose both muscle and fat in great quantities,  you will undoubtedly weigh less, but you will not be more healthy.

The best route is a fitness and nutrition plan that encourages fat loss and maintaining lean body mass as much as possible.
