Several studies have suggested that high protein diets
may be effective for weight loss and prevention of weight
regain. Recent findings suggest that these effects of high protein diets are related to increased satiety and energy
expenditure, although underlying mechanisms are not well
established. Satiating effect of protein may be helpful to
control calorie consumption. Also high protein diets may
increase loss of body fat and preservation of fat free mass
during weight loss period. Positive changes in body
composition and weight loss via high protein diets help to
improve certain metabolic problems related to obesity.
Although increased protein intake may be expected to be
beneficial in obesity treatment, it is important to consider
the adverse effects of excess protein intake. Therefore,
individualized approach is necessary based on the
evaluation of one's usual protein intake and health status
of each individual.
