A fad diet is an unhealthy and an unbalanced food intake in order to lose weight quickly without the tedious process of exercising. Apparently, a person on a fad diet is not shedding out fat, instead, he or she is losing water weight which is dangerous. In comparison, good nutrition is the opposite of fad diet. With good nutrition, a person is not aiming to lose weight, rather, he or she wants to maintain the right weight which is within the normal BMI level. Furthermore, with good nutrition, he or she promotes good health by not harboring lifestyle-related diseases such as diabetes mellitus, stroke, and heart diseases.
