Here's a very nice summary of how Optimistic Concurrency works on database updates and information on how it compares to Pessimistic concurrency.
Optimistic Concurrency | Microsoft Docs[^]
I was searching for a solution related to this and didn't know what it was called and stumbled into this and then it helped me solve the challenge I was confronting.
A good, informative read that all devs should know about.

That's it, I finally admitted I am fat.
There isn't any point pretending, I am gross. So, time to do something about it:
Diet, basically zero carbs/low GI. Rye bread for example has a Glycemic Index of 45, not much more than broccoli, so that is an OK carb.
Also taking apple cider vinegar, 2 teaspoons before a meal, and at night. Unpasteurised. Apparently it has good bacteria in it.
Started a few days ago and losing half a kilo a day:
121.3
121
120.5
120
119.5
It works. Really.
My target is 100 kgs, I weighed that when I was ~30. I cold hit this by the end of March at this rate! Ideal, want to go skiing, and NOT lugging 20kgs around is going to make me ski great! 
One note, I was very tired for two days on zero carbs, so I had a rye bread cheese fondue. About 1000 calories in total. Feel much better.
And I am allowing myself red wine, say three glasses or so a night.

Surely, croissants contain nothing but ok carbs as well - not to mention pains au chocolat???

Note that losing weight too quickly is (a) dangerous to your health, and (b) may lead to yo-yo dieting, because you don't actually change your life-style in the long term.
IIRC, Weight Watchers recommend losing about 0.5 kg a week on a balanced diet. Note that this is for people who weigh 60-90 kg. I'M not sure what their advice would be for those who weigh 120 kg.
If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

I intend to make this a long term thing. It is easy to stick to, and you are not hungry. Meat, veg, nice sauces, and even as I said a cheese fondue, there is nothing NOT to like about that lot!
Because of the amount of physical work I dont on the house, I am currently rebuilding a wall knocked over by a car, I got some work out drink, high energy and nutrients, no sugar. I am going to try that when I get tired, it might kick the body into fat burning mode.
Look, body builders trim down before events, and work out while doing so to get their fat down to really low levels, so they must know some tricks.

Quote: high energy
Quote: no sugar
Choose one. Energy comes from sugars.
There is *nothing* wrong in sugars, fats or carbohydrates. They just need to be correctly rationed and most of all the snacks and continuous eating must be reduced, preferrably to 0.
We do a fully cerebral and static job, which stresses us a lot and induce false hunger (more like: "I need something to fill me and give me endorphines - HEY is that a chocolate caramel nuts dried fruit bar??! That will do!"). Willpower is the only cure for that stress induced hunger.

The body can turn fat (and protein) into sugars. Thats the key.
|

But not short-term energy like what one wants from energy drinks. They might and usually will replenish minerals lost and give some vitamins whihc help the overall efficiency of the body but there is no fast energy without sugars.

I know, this drink isnt sugars, it is nutrients and energy boosters.

Yeah, they do drugs.

Start running, if you don't do it yet.

That's no good, you can't run from that. The weight catches up with you eventually - trust me, I know...

Bad advice. He wants to do zero carbohydrates. You just told him to go racing with an empty fuel tank. It's not so bad when a car runs out of fuel, but it's not so easy to restart him when he collapses.

Balanced diet and running is far better than zero carbohydrates.

True: if you want to get fit
False: if you want to lose weight.
Only way to loose weight: eat less

But it SOUNDS like loose. Stupid language English is!

I like spelling 'learned' as 'learnt', the way it is pronounced. it is a valid spelling still though not common.
English is basically a mess though, I think we should just spell stuff how we like, it always was that way.

Alas, you've must have gotten a hacked copy of the diet book I was thinking of writing.
"The Eat Less Diet"
Page 1: Eat Less
Page 2-144: (blank, for your notes)
Based on the premises that:
If you eat fewer calories than you burn you will lose weight.
If you eat more calories than you burn you will gain weight.
Anything else is just a gimmick.

In the long run (pun intended), yes, but some quick results may help you to get started.

Tried that, I am too heavy. Started getting sore ankles. Cycling is better, though at the moment I am doing quite a lot of physical work.

at 120kg he really should lose a bit of weight first. The rule of thumb I've seen quoted here is that above 250lbs (113 kg) the peak loads running puts on your joints begin to exceed the maximum that the joints were designed to withstand and the risk of a soft tissue injury starts to increase rapidly.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?
