138: Calvin Scheller (@calvin_scheller) — What influences our appetite? The fascinating physiology of appetite regulation + how our brain, hormones and environment shape when/how much we eat


Listen Later

Such a fascinating and jam-packed conversation with my guy - Calvin Scheller. Calvin has a real talent for breaking down complex science + together we dive into what actually influences our appetite. Topics discussed:

-What drives people to eat?

-How environment, psychology, and physiology influence what (and how much) we eat.

-Defining appetite: what it actually means.

-The role of the hypothalamus and brain in assessing our body's needs.

-Orexigenic vs. anorexigenic signaling (aka the signals that drive us to eat more or less).

-Hormones you’ve probably heard of - cortisol, serotonin, and dopamine & how they impact hunger.

-A deep dive into leptin: what it is, how it works, and what leptin resistance means.

-Why people with higher body fat levels might actually experience more hunger, not less.

-GLP-1 and GIP: their role in appetite suppression and a discussion around common weight loss medications.

+ so much more in-between. I loved this chat + I know you will too!
