Anna Nicole weighed about 125 pounds most of her adult life. However, it seemed like whenever Anna Nicole gained weight it was easy to lose and get back to 125. But when she wanted to go below 125 it took forever, and even the slightest deviation from her diet got her back to 125. What explanation would you give Anna Nicole?

A) use better diet products
B) start a reality TV show
C) Her weight, 125, is her set point. Leave it alone.
D) her BMR is not tied to her set point

The concept of a set point theory means that the body has a weight range that it naturally maintains without effort. For Anna Nicole, this seemed to be around 125 pounds. Going below this weight could be difficult as her body may have been resisting this change and trying to regain the weight back to the set point. Therefore, the best explanation for Anna Nicole's experience is that her weight, 125, is her set point, and she should leave it alone. Options A and B are not relevant, and D may be a contributing factor, but not the best explanation for her experience.
