Only do the above diet if you want do sacrifice your muscle, you will not lose fat by cutting down on protein intake (in fact it's possible to increase your body fat by cutting down on protein because you will likely substitute carbohydrates for it). If you want a safe way to lose weight, eat healthily and exercise for 4 days a week. In 4-5 weeks you can be reasonably fit, depending on the routine and eating habits.
Do not buy into mystical diets which have not nutritional explanation, they will only harm you. DIETS DO NOT WORK, EXERCISE AND HEATLHY FOOD IS THE ONLY EFFECTIVE WAY TO LOSE WEIGHT.
Remember: "There is no shortcut to anyplace worth going".
