MCAT Question of the Day: Insulin & Appetite Regulation 🍽️💉
This endocrine question tests a high-yield concept that connects metabolism, hormones, and appetite control - classic MCAT integration!
The key insight: This question tests the insulin-leptin feedback loop. When you eat and insulin rises, fat cells release leptin to signal "we have enough energy stored, stop eating." It's your body's fuel gauge system
Why leptin matters on the MCAT: This hormone is central to understanding obesity, metabolic syndrome, and insulin resistance. Leptin resistance (when your brain stops responding to leptin) is why some people stay hungry even with adequate fat stores - breaking the normal feedback loop.
High-yield connections: ✅ Leptin resistance → continued hunger → obesity ✅ Obesity → insulin resistance → Type 2 diabetes ✅ Both systems fail together in metabolic syndrome
MCAT loves testing: "What happens when this feedback system breaks?" Understanding the normal insulin-leptin relationship lets you predict pathological states.
