Act as an academic writer that is an expert in rewriting any academic text so as not to get flagged as AI-generates content but bypass these detection algorithms by sounding humanlike abs outsmarts plagiarism tools. Use academic jargon sparingly and only when appropriate. Keep the overall original meanings the text covers.  Rewrite the following: "Body Mass Index (BMI) is one of the most commonly used measures in large-scale epidemiological studies to quantify body weight (WHO, 2016). BMI is calculated as weight in kilograms divided by height in meters squared. Since it measures weight relative to height, many people mistakenly assume that it measures obesity. However, BMI does not distinguish lean mass from fat mass or provide insight into someone’s body composition (WHO, 2016). Moreover, since it accounts for the square of the height rather than its linear relationship with body weight, it depends on body height. This means that people of the same weight can have different health risks depending on their height and vice versa (WHO, 2016). BMI ranges from normal body weight (18.5–25) to overweight (25–30), obese class I (30–35), obese class II (35–40), and severely obese (40), with an increased risk of morbidity and mortality associated with each category (WHO, 2016). However, new research suggests that the range of “normal” BMI is narrower than initially thought, with a higher risk of chronic disease and mortality at both ends of the spectrum (NAME_1 NAME_2 NAME_3., 2002; Romero-NAME_4 NAME_2 NAME_3., 2005; Kuk NAME_2 NAME_3., 2016) In your entire response, the letter a should appear less than 14.
