BIA is a state-of-the-art assessment in body composition analysis. In less than 5 minutes, the results are available through a sophisticated computer software, giving a breakdown of lean body tissue, bone tissue, fat, and total water. One of the earliest signs of failing health is a shift of fluid from intracellular to extracellular, indicating possible body toxicity. The BIA also gives resting metabolic rate of calories burned in 24 hours, which becomes important information in formulating a menu plan based on your specific body calorie needs and biochemistry. This information is invaluable for those on weight management programs or detoxification programs, for those working to build muscle mass, and to track the aging process and general health status.
