Hi, how to understand "but otherwise"' in the following sentence? Does it mean "and" "besides"? So in this context, it means "healthy and obese"?🙏🙏
"Researchers assigned 57 obese but otherwise healthy people to one of these two groups or a control group, in which people were simply weighted at the end of each month."
I also notice "obese" in here is a noun, how could it happen, or is it an omitted usage?🙏🙏
