The diet lasted for eight days with the dieter only eating one type of food for two days each.
If the dieter followed the regimen for the full eight days, he or she would enjoy a short-term weight loss. However, as this regime was not sustainable over the long term, the person undertaking the diet soon regained the weight as he or she returned to their normal diet. In addition, the lack of variety in the diet meant that many people failed to complete the diet regimen. As well, the diet was not a balanced diet providing the dieter with their nutritional needs such as calories, protein and vitamins.
For these reasons, nutritionists and doctors were critical of the Israeli Army diet and it declined in popularity. It is now regarded as a classic fad diet like the grapefruit diet or the cabbage soup diet.
