According to a new study more people in the world are obese than underweight, and by the year 2025 roughly 20 percent of the world’s population will be considered medically obese. Analysis conducted by the Non-Communicable Disease (NCD) Risk Factor Collaboration looked at 19.2 million participants and discovered that the global obesity epidemic is set to become much, much worse. Tctmd.com reports: Researchers led by Mariachiara Di Cesare, PhD (Imperial College London, England), looked at BMI trends of adults living in 186 countries between 1975 and 2014. Using global models to calculate increases over time, they estimate that the number of obese people (BMI ≥ 30 kg/m2) increased from 105 to 641 million over the study period. Breaking it down by sex, the proportion of obese men tripled (3.2% to 10.8%) and the proportion of obese women more than doubled (6.4% to 14.9%) since 1975. Meanwhile, they estimated that the proportion of underweight people fell by about one-third in both men (13.8% to 8.8%) and women (14.6% to 9.7%). In an age-corrected analysis, BMI increased from 21.7 kg/m² to 24.2 kg/m² in men and from 22.1 kg/m² to 24.4 kg/m² in women; these shifts equate to the world’s population gaining 1.5 [...]
