Same. I don't drink caffeine after noon and I have a much easier time maintaining a functional sleep schedule.
I had a older relative who often complained about poor sleep. I asked if they drank caffeine in the afternoon and they scoffed at the idea it could be the issue. But I have noticed they are not drinking caffeine late in the day now, and the complaining about poor sleep has ceased.
He provides all the science behind the current obesity epidemic, backed up with studies done on humans.
Obesity is a hormonal problem... Insulin makes us fat.
Current fads suggest eating ALL THE TIME.
This puts people in a state of high insulin all day, everyday. This is bad.
Intermittent fasting based around a common sense diet (limit sugars and starchy food to special occasions) will lower insulin levels, and cause the body to burn fat instead of insulin.
The keys is not what to eat, but when to eat and how often... and drink Apple Cider Vinegar. :P
