Alcohol, Weight Gain And Weight Loss, A Calculator.

Alcohol is not just another a food, the body considers it a toxin and prioritises its metabolism over that of food.

Alcohol And Weight Loss Or Weight Gain.

I Was Really Surprised By The Effects Of Smallish Amounts Of Alcohol, Is Three Pints Really A Lot?


The calorie content of alcoholic drinks is well known so it must be easy to calculate a food plan taking this into account, mustn't it?

Anyway, its all just a modern over-reaction to a minor issue, people have been drinking forever and it never did them any harm.

The problem with alcohol is that is not treated by the body as normal food, it is treated as a poison to be got rid of as fast as possible. A search for alcohol dehydrogenase (ADH) will explain the process in more detail, but the important point is that ADH exist only to process alcohol....

....And that when it is active the intake of nutrients and energy from normal food is is suspended.

Alcohol also affects the rate at which food moves through the whole digestive system, it can slow down the movement of food from the esophagus to the stomach or trap food in the stomach rather allow it to move to the small intestine. On the other hand it can also cause the food to be moved through small and large intestines faster.

As food is not processed instantaneously it is very difficult to determine the effect that these changes have. If the digestion of the cheese roll and banana you had for lunch is delayed by an hour by the accompanying pint does it really matter anyway?

What about 2 hours, 4 hours or 8 hours, as the amount of alcohol increases so does the risk that food moves through the digestive system without its nutrients being fully extracted.

It is likely that a single glass of wine or a pint will be processed sufficiently quickly that this question probably isn't all that important, but is the truth that it wasn't just one glass but all or most of the bottle?

So if you do drink a bottle of wine a day how much food passes through you without yielding much of its nutrients and energy?

Unfortunately ethical concerns mean that there is very little research on how a bottle of wine a day affects what would otherwise be a well balanced diet.

Yeah, if alcohol is really so bad then how come we have a process to metabolise it at all, after all we can't metabolise petrol?

Specialists seems to be divided, some have it as a recent ability resulting from societies deliberately brewing and distilling, making it a new capacity that is a only a few thousands of years old. Others put it way back between 10 and 70 million years ago as a way of coping with rotting fruit.

Having said this both canine and feline ADH exists and many of us know "Rover who likes a half" although vets deeply frown on such things.
Below we can see some beer being processed and it blocking the digestion of food, Generic Meal 700kc(3).

68.641 1716 490 1839 14 66/0 52 Digest Generic Meal 700kc(3) high blood alcohol has defered protein processing

The basal energy need is being met by Basal usage 68kc, Fat 47kc, Glycogen 21kc, protein 2.2g as the alcohol that has been absorbed into the blood stream is not yet providing any energy.

It needs to be metabolised from the blood before there any energy available from it so there is a delay before it becomes usable.

As we see from below Basal usage 68kc, Fat 22kc, Alcohol 46kc, protein 2.2g once alcohol has been processed it becomes the primary energy source replacing glycogen/glucose and fat.

The process is the alcohol with the help of ADH becomes acetaldehyde and then with the help of ALDH becomes Acetate and then Ketone Bodies (Ketone Bodies are ketones and molecules that are very similar to ketones), Fatty Acids and Carbon Dioxide.

This calculator shows the energy available from this metabolism separately from the ketosis generated ketones.

There is a general principle that people can metabolise one unit per hour is, but this is only a guide, a range of 0.7 units to 1 unit per hour may be more reasonable. There is also some debate on how much the concentration of alcohol affects its metabolism, particularly at low levels.

This means that as most people process less alcohol per hour than needed by basal functions there will never be a big build up of alcohol derived ketones.

There is also some degree of uncertainty on the effect alcohol on ketosis, alcohol defers carbohydrate processing which should increase ketosis, but how much alcohol inhibits ketosis is unclear.

Also does the backing up of carbohydrate processing lead to a surge when the alcohol is metabolised leading to small amounts of carbs causing an over-reduction of ketone production?

How Long Does Alcohol Stay In The Bloodstream?

3 Pints With Breakfast, What Will Happen?
Okay 3 pints with breakfast is a bit silly, but it does mean that we start the example off with an empty stomach.

In this example we start of with the beer and breakfast and the delay in metabolising alcohol allows a little bit of the breakfast to be digested.

The easily readable Very Brief Report shown below needs to do so much compression and summarising to get to one line that some things seem to occur a bit earlier or later than they actually do.

The more detailed report that follows it is a more precise version, with Digest Fried Breakfast(1) being supressed throughout most of the time period.

For an even more detailed result it may worth running the calculations with a 15 minute calculation interval.

As shown in the more detailed report below once the beer starts to be metabolised the digestion of the breakfast stops at around 01:00 and restarts at 11:00.

This is almost half a day, exactly where in the digestive system is the breakfast now and what has been lost during its passage?

We also see the difference in the English and Scottish drink drive limits and an extra couple of hours needed to be below the lower limit.
