Around 8 seconds.
The swallowing tract extends from the mouth to the stomach. The act of swallowing normally occurs in three phases. In the first phase, food or liquid is contained in the mouth by the tongue and palate (oral cavity). This phase is the only one we can control.
The second phase of swallowing begins when the brain makes the decision to swallow. At this point, a complex series of reflexes begin. The food is thrust from the oral cavity into the throat (pharynx). At the same time, two other events occur: A muscular valve at the bottom of the pharynx opens, allowing food to enter the swallowing tube (esophagus), and other muscles close the airway (trachea) to prevent food from entering the airways. This second phase of swallowing takes less than half a second.
The third phase of swallowing begins when food enters the esophagus. The esophagus, which is about nine inches long, is a muscular tube that produces waves of coordinated contractions (peristalsis). As the esophagus contracts, a muscular valve at the end of the esophagus opens and food is propelled into the stomach. The third phase of swallowing takes six to eight seconds to complete.
Thus, swallowing is a very complex act, requiring the normal function of the brain, several nerves and muscles, and two muscular valves, as well as an open, unconstricted esophagus.

I found the book to be very informative and easy to read.
I've lost 17 pounds in 12 days, I'm just concerned that I'm losing too much weight, too quickly. I will admit I haven't followed the guide exactly. I'm not sticking perfectly to the listed foods and meal plans (but mostly) and doing very little exercise, but the weight keeps flying off.
It clearly works and if I'd followed it exactly I think it would scare the living daylights out of me because of the amount that I'd lose. So thanks again for the information. I've never purchased anything like this before because they are usually full of trash, but 3WD has been a pleasant surprise.
Get started today!

One of the numerous locations that Sofia provides through his tourists is Saint George Rotunda church.

About five seconds max. As soon as you swallow waves of pressure move through your oesophagus (food pipe) to transfer food directly to the stomach. It's quick.

Im not entirely sure but i know that it is better to eat slower as it does not register with the brain straight away which is why you can eat and eat feeling hungry and then suddenly feel full

I'll venture to say it happens quickly. However, I'm living proof that it doesn't take long for it to go from your mouth to your hips!
