Fit for Life: Pros and Cons

It is impossible to refrain from repetition stating that practically everything in our life has its benefits and drawbacks. Or if to express it in other words what is good and beneficial for one person has a negative impact on the other. The same can be applied to the choice of particular diet and dieting process as the whole.

Fit for Life diet appeared on the American market in the middle of 80-s and immediately had a huge success. The diet book was sold in million copies and million people tried the advantages and disadvantages of a new diet. Was this diet of any help in achieving their main aim – losing weight? Or did it turn out to be one of the quick-passing fad diets?

Let's weigh all pro and con arguments and find out whether the Fit for Life strategy has a potential of a well-balanced and safe diet.

The diet plan includes 70 % of fresh fruits and vegetables and 30 % of other food groups. The consumption of fruits and vegetables in these amounts is seen as a big PRO of this diet, because nobody will deny the value of vitamins and minerals that the body gets from fruit and vegetables. Besides it lowers the risk of developing of heart disease and cancer.

On the other hand this point is also a CON in this diet. Firstly, fruits and vegetables are vitamins rich but they can’t provide all necessary nutrients and secondly, the body needs a mix of all nutrients – protein, fat and carbs and 30 % of foods for these groups seem to be not enough to ensure an adequate nutrition.

To the other PROS can be related the simplicity and relative easiness. There is no restriction of calorie intake. The recommended food can be eaten in any amounts. So, the portions needn’t be controlled and one wouldn't feel pangs of conscience after eating a little bit more than usual.  The authors of the Fit for life diet use the theories of Natural Hygiene, an alternative medicine which has very ancient roots and is based on some nature-related methods.

And one more PRO for those who aim at quick results: if to follow the proper food combining rules and the right timings of food intakes the diet promises increased energy, improved health and rapid weight loss.

The main CON of the diet plan can be affirmations of many nutritional specialists about the lack of scientific background or clinical evidence behind the fact that food combining causes weight loss or assists in weight maintenance. In fact, some principles of the program disagree with established nutritional rules of American Dietetic Association (ADA).

Some theories of Marilyn and Harley Diamonds are defined as pseudoscientific; for example, human body can’t be “cleansed” or “clogged with food”. Our digestive system can handle many different types of food at a time; and some food combinations on the contrary enhance food absorption and digestion.

Since some food groups are restricted and meat and dairy products are strictly limited the dietitians express their concern that the human organism will not get sufficient amount of protein and will suffer from the deficient intake of zinc, iron, vitamin B12 and D. The limitation of dairy products can jeopardize calcium intake as dairy products provide more than 70% of calcium in the diet.

The CON of this diet plan is also the fact that food combining rules are sometimes very difficult to follow. They can be rather confusing and the dieter should have good knowledge about nutritional principles and should know how to differentiate starches from protein and carbohydrates and how to combine them in a proper Fit for Life meal.

So, as we have seen the Fit for Life diet has both positive and negative sides. What outweighs – pros or cons and what is more important on the scales of dieting process everyone should decide for himself.
