Please help me answer this using the concept of set points must relate to human physiology. Thx 3. Joe and Anna were having a discussion about their BMIS (body-mass index). Joe complained that when
he was 19 years old, he could eat pizza all the time and never put on weight. Now that he's 38, no
matter how hard he tries dieting and exercise, he feels that his body always seems to want to return to
being slightly overweight. Anna, on the other hand, who is the same age as Joe, says that her BMI
hasn't changed much at all since she was in high school. What gives?
Using the concept of set points, hypothesize an explanation of the differences Joe and Anna are
experiencing now (compared to each other), and throughout their individual lives.
