The Biology behind Hunger and Satiety

It is a very good point to be noted.

Thank you!

Yes, more conscious eating decisions means a better health

True! Following to a strict routine can greatly improve our overall health.

Great breakdown of how hunger and fullness work! It’s fascinating how hormones like ghrelin and leptin send message to the brain to regulate appetite, and how the gut-brain axis plays such a key role in energy balance. Understanding these signals helps us make smarter choices about eating and health. Thanks for the clear explanation.

Great explanation of how hunger is hormonally and neurologically regulated. For most people, improving sleep and prioritizing protein- and fiber-rich meals would likely make the biggest day-to-day difference in controlling unnecessary hunger.

For me, maintaining proper sleep and regular meal timings would probably make the biggest difference. Poor sleep and irregular eating really disturb hunger signals, while consistent routines help keep appetite and energy levels balanced.

Never knew hunger could vary. The hypothalamus is a marvelous structure capable of passing different stimuli to denote different mechanisms. Knowing these signals given by our body and acting according to them may help lead a healthy and happy life.

I have HEDONIC HUNGER 98% of the times, and because it is mostly PLEASURE DRIVEN and though I have complete knowledge of how this is completely unhealthy and unnecessary.I agree that most of the times despite of the inner resistance I still give in to my desire for food.Lack of self-discipline is what contributes to it, and though I very much intend to change this, I also realise that its not going to be easy.What do you think I should do?(guilty!)

Prolonged hedonic hunger can gradually dysregulate appetite pathways and contribute to leptin resistance over time, making it harder for the brain to register fullness. That’s where awareness becomes crucial. Understanding the difference between genuine ghrelin-driven hunger and reward-driven cravings can help prevent overeating and long-term weight gain.

Though this topic looks familiar,it was exciting to read about types of hunger.Homeostatic hunger is the ideal one.Hedonic hunger is what many of us are having I guess.

As a biotechnologist, I’d highlight that beyond ghrelin and leptin, other hormones like insulin and cortisol also play a big role in hunger regulation. Insulin spikes after meals and helps shuttle glucose into cells, but erratic insulin signaling can confuse satiety cues. Cortisol, the stress hormone, often drives hedonic hunger, making us crave high‑energy foods even when not physiologically needed. GLP‑1 and CCK are equally important. They slow gastric emptying and reinforce fullness. In daily routine, balancing sleep, stress, and meal timing keeps these hormones aligned. Honestly, people often overlook stress management, but it’s just as critical as diet or sleep for keeping hunger signals in check.
