In this video, Dr. Berg talks about when is the best time to do One Meal a Day (OMAD). There are two parts of the nervous system called Sympathetic Nervous System (Flight or Fight) and the Parasympathetic Nervous System (Rest and Digest). 8 o’clock in the morning is the peak cortisol or peak of the stress hormone so it is not a good idea to consume your one-meal-a-day during the morning even though your stomach is at the most acid during this time. The best time to eat to work with the body is during late afternoon or the evening because you are going to get maximum digestion when you are under parasympathetic control.

Parts of the Nervous System:
• Sympathetic Nervous System (Flight or Fight) – This is when you are reacting to stress.
• Parasympathetic Nervous System (Rest and Digest) – This is during the latter part of day (Evening) when your body is winding down.

Alright. So someone wanted to know when is the best time to do one-meal-a-day? So let’s just talk about that. There’s different view points and these are not absolute. Some people do very well in the morning eating their meal, some time in the evening, some time in the midday but I just wanna give you my two cents on a concept that kind of works with your body a little bit more than against your body. There are two parts of the nervous system you have the Flight or Fight which is called the Sympathetic Nervous System, this is when you are reacting to stress and during the day your body is a little bit more stress, then you go to bed at night when you are resting this other system kicks in called Parasympathetic Nervous System another name for that would be Rest and Digest. So towards the later part of the day, your body’s gonna wined down and you are gonna kick in this parasympathetic, but during the day, it is more of flight or fight pushing yourself. In fact, at 8 o’clock in the morning, that’s when you have your peak cortisol, that’s the stress hormone. So if you wanna work with the body, it might not be a good idea to consume your one meal a day in the morning even though your stomach is most acid in the morning so you can digest most of the protein, based on the cortisol, it might not be a good idea. I also found just by talking with hundreds of people and interacting with people that when they do the one meal during the day, let’s say at lunch time, a lot of these people get tired after they eat. I think the best time to eat to work with the body is in the evening or late afternoon. So as we shift to more sympathetic to more parasympathetic we get more complete digestion. Because you don’t wanna eat when you are stressed or during exercise because that is gonna inhibit digestion. You are gonna get maximum digestion when you are in the parasympathetic control. I think a lot of people right now that are watching that consume that one meal a day in the later afternoon of evening. But for those of you that aren’t, you might wanna try pushing that one meal a little later and just see how you feel. And also if you are doing OMAD, type down the time that you eat. I’m curious.
