What role does leptin play in body weight regulation?

Leptin helps regulate body weight by informing the brain about the amount of body fat, influencing food intake and energy expenditure.

What is leptin resistance?

Leptin resistance is a condition where the brain doesn't respond effectively to leptin signals, often associated with obesity.

What happens to leptin levels during weight loss?

Leptin levels typically decrease during weight loss, which can increase appetite and decrease energy expenditure.

What is the relationship between leptin and insulin?

Leptin and insulin interact in the regulation of energy balance, with both hormones impacting appetite and metabolism.

What diseases are associated with leptin dysregulation?

Leptin dysregulation is associated with obesity, type 2 diabetes, and metabolic syndrome.
