Final answer:
C) Through body fat percentage measurements Body fat percentage measurements are the most accurate method to determine body fatness. Skinfold measurements, DEXA scans, and waist circumference are good indicators of body fat and its distribution.
Step-by-step explanation:
To determine intensity for body fatness, the most direct and useful method is C) Through body fat percentage measurements. Counting calories is useful for understanding energy intake versus energy expenditure, and body weight can provide general information but does not distinguish between fat and lean mass. Daily steps taken are more indicative of activity levels rather than body fatness. For a precise measurement, body fat percentage is assessed through various methods such as skinfold thickness measurements using calipers, Dual-energy X-ray absorptiometry (DEXA), or Bioelectrical Impedance Analysis (BIA). These methods provide a clearer understanding of an individual's proportion of fat relative to their total weight, which is a more reliable indicator of body fatness than weight alone.
Tools like the skinfold test measure the thickness of skin at various parts of the body and compare it to standards to assess body fatness, while DEXA scans measure fat content by directing low-dose X-ray beams through the body. Waist circumference is another measure that indicates body fat distribution, particularly visceral fat, which is a strong predictor of health risks.The intensity for body fatness can be determined through body fat percentage measurements. This method involves assessing the amount of fat mass in relation to total body weight. Techniques such as dual-energy X-ray absorptiometry (DEXA) and skin-fold tests can be used to measure body fat percentage.
