I am an intermittent faster you know 12 to 16 hours every day and a lot of times I'm not eating an enormous Li protein-rich breakfast but when I travel when I'm jet-lagged on outside of my time zone I actually make it a point to eat a protein-rich breakfast in whatever area of the world I happen to be in when it's breakfast time because it's one of the best ways to maintain circadian rhythm and it turns out that has an impact on leptin sensitivity as well
