A state of balance between intake and excretion of nutritive material, thus, there is no increase or loss in weight


Nutritive equilibrium is a state of balance or equilibrium between intake and excretion of nutritive material resulting in a weight that is relatively constant. This means there is no increase or loss in weight. Weight gain pertains to the increase in body weight. An increase in body weight is generally manifested as an increase in muscle mass, fat deposits or retention of excess fluids. Weight loss, in contrast, is the reduction of the total body mass. It generally involves a loss of body fat, muscle mass, or fluid. One way to determine weight loss or weight gain is by evaluating the body mass index (BMI). BMI is a measure of the body weight relative to the square of height. This ratio is often used as a basis if the weight is optimal, excessive, insufficient, or in nutritive equilibrium. Both weight gain and weight loss, when beyond the range of acceptable weight to height ratio, may provide an insight for an individual's health. They may also indicate an underlying nutritive disorder. For instance, an extremely excess in weight may indicate obesity whereas an extremely low weight may be an indication of malnourishment. Cachexia is a condition characterized by a weight loss that is not caused by a reduction in caloric intake or an engagement in workouts or physical exercises but possibly by a disease or a disorder.
