Would an unload is harmless?

Many women's which are working with me as systematically unloading, as one women within two days eating wetting and cooking salt free rice, other is kefir or apples, and other nothing eating as starving,and am asking why you are doing this?they answering for slimming,removing slags and feeling better, maybe this an epidemic,that one is doing and next are repeating, maybe specialist would answer me, are they true benefit to us?
Am answering,if you are not risk in obesity, thus never do this, do not avoid itself a full breakfast, lunch and dinner, but who is in risk you must do this, and who having obesity also benefit.
As within one unloading day you can lost are 600 gr of mass,so as such zig zags in meal assisting for metabolism shaking and fat burning,having in subcutaneous fatty cellulose.
But unload day is just doing one day/week, and not often, and therefore you are getting harmful results. And here you are losing vitamin c, mineral salts, carbohydrates and on the fruit day and proteins, fats,vitamins groups B, and in result a principle of balancing meal destroy,and you are in risk loosing a health. If these days doing on 2-3, or 4 times/week you are getting deep destroys of metabolism, leading to diseases,as deficit vitamin A, causing a chicken s blindness, and grow in delay, and ferrum deficit is anemia display. And how you are needing unloading right, this is depending of health, diseases display, thus visit a doctor, and to 19-20 y.old when keeping growing  are benefit protein days, are fish, meat, curd, as protein for theirs is building material, is a base for stucture cell of elements in tissues, And in gout, atherosclerosis are limiting meat, they are benefit in fruit, vegetable,kefir days, and in colitis,gastritis are raw hard fiber vegetables of cabbage, turnip, cucumbers, radish red are avoiding, in diabetes if doctor allows is not eating apples,dried apricots and etc sweet fruits.
