Karen has recently completed a very successful diet program and is now concerned about maintaining her weight loss. One of the challenges she must face is the fact that
A) nobody is ever successful in maintaining weight loss, because obesity is caused by your genes.
B) her lower level of fat will stimulate the release of lower levels of leptin, leading to increased hunger.
C) her lower level of fat will stimulate the release of higher levels of leptin, leading to increased hunger.
D) dieting has made her resistant to leptin, leading to increased hunger.

Question

Quizplus · Accepted Answer

Leptin is a hormone produced by fat cells that helps control hunger and metabolism. When someone loses weight, their fat cells produce less leptin, which can lead to increased hunger and difficulty maintaining weight loss. This is why choice B is the correct answer, as it correctly identifies the challenge Karen must face. The other choices are incorrect: A is untrue, as some people are successful in maintaining weight loss; C is incorrect because higher levels of leptin would actually suppress hunger, rather than increasing it; and D is incorrect because dieting does not make a person resistant to leptin, although being obese can potentially lead to leptin resistance.
