Leptin is a hormone that assists in regulating both appetite and metabolism. Leptin was only discovered in 1994 - therefore research is only very recent.
Leptin levels are generally proportional to body fat, as leptin is released by fat cells. It is thought that many obese people may have developed leptin resistance - whereby the body fails to respond to leptin signals. This begins a cycle where more leptin is produced.

But the book Mastering Leptin has more than the 5 rules. It is very scientific so the majority of people won’t care for wading through the mountains of scientific research he summarizes. Also, I’m finding that the 5 Rules don’t work for everyone. My body seems to like waiting 12 hours between eating dinner and eating breakfast the next day, but going 5 hours between meals was not reasonable. I became shaky and didn’t feel well at all, even though my blood sugar readings were completely normal, so it wasn’t due to hypoglycemia. I think a better plan for dealing with leptin resistance is Dr. Rosedale’s diet, even though it’s more stringent. Dr. Rosedale recommends not eating within 3 hours of going to bed, so by the time you add up the 3 hours plus the 7-8 hours of sleep, it equals Byron Richard’s 12 hour recommendation. Byron Richard’s supplements are also way over priced, and many of them simply aren’t necessary. Rosedale recommends supplements, too, but you don’t have to buy “his” brand of them, and you can get by on fewer than he recommends.
