Which physiological responses are characteristic of the body’s attempt to return to a set point after weight loss?

• A. Increased hunger signaling and reduced basal metabolic rate
• B. Decreased ghrelin production and increased thyroxine secretion, both of which reduce appetite and accelerate metabolism
• C. Permanent elevation of BMR with no change in hunger signals, making weight regain unlikely after loss
• D. Loss of hypothalamic regulation entirely so caloric intake becomes random and unrelated to physiological signals
