Final answer:
Persistent changes in hormone expression can affect long-term hunger and weight regulation.
Step-by-step explanation:
The statement is B) False. In response to dieting, there can be changes in the levels of hormones such as leptin, ghrelin, PYY (peptide YY), GLP-1 (glucagon-like peptide-1), and CCK (cholecystokinin). However, the statement that these changes necessarily lead to long-term hunger and weight gain is an oversimplification.
Leptin is often referred to as the "satiety hormone" because it signals to the brain that the body has had enough to eat. Ghrelin is known as the "hunger hormone" because it stimulates appetite. PYY, GLP-1, and CCK are involved in regulating feelings of fullness and controlling food intake.
While dieting can influence these hormonal changes, the body's response to weight loss is complex, and individual variations exist. Factors such as the type of diet, overall health, and genetic predispositions can play a role in how these hormones respond to changes in diet and weight.
It's important to note that sustainable weight management involves a combination of a balanced diet, regular physical activity, and individualized approaches that consider the person's overall health and lifestyle. If someone has concerns about weight management or dieting, consulting with a healthcare professional or a registered dietitian is recommended.
