Note the caveat, “...with no other health problems.”
Thing is, if you are obese, chances are you do have health problems. Most likely, one of the major problems is cardiac disease. And you probably aren’t aware of it.
A bogus study, to say the least.
You hit the nail perfectly. They must be describing the fat people that eat ten pounds of atlantic salmon, three loaves of whole wheat bread (unfortified with iron), one dozen hard apples, and work 16 hours per day as a lumberjack.
Yes exactly right. Fat people “... with no other health problems” were compared to skinny people - with or without other health problems.
Some people can carry that weight and not develop “other health problems” - good for them. But they are not usual.
Usually fat people develop a HOST of health problems.
