Ideal Final Result. Or how to solve it?

What is it all about?

As I mentioned in the previous post I’d like to share with you how anyone can be an inventor and solve everyday problems from simpler to not so using the methodology from the Theory Of Inventive Problem Solving (aka TRIZ in Russian).

Today we will look at a real problem that I faced while living in an apartment building in Israel.

Inventive problem

That apartment building had a public storage where tenants could store their bicycles and other stuff. So it was natural for me to store my own bike there as well. But it happened that someone stole the black valve cap on one of the tires of my bike.

This is how the valve cap I am talking about looks like

How to solve it?

Well, how would you solve this issue? I can tell you right away that at that time there were no cameras installed in the the storage room, and installing one would be prohibitive. It was possible not to do anything as well as a solution.

So let’s try to approach this problem using tools from TRIZ. As I mentioned before that’s first identify a contradiction that happens in this situation. I want to have my valve cap in place without people ‘borrowing’ it. Then more specifically, we may say that we want the cap to be distinguishable if it is stolen, and ideally not to be stolen in the first place. This is what called in TRIZ as administrative contradiction.

The issue lies in the fact that the valve cap is black on any of the bikes and it is indistinguishable when stolen. So the technical contradiction as it’s known in TRIZ, means that the cup isn’t distinguishable when it should be clearly distinguishable.

Ideal Final Result (IFR)

Now, it’s time to introduce one more term, which is an Ideal Final Result. It will help us to focus the contradiction and to resolve it. Ideal Final Result means that we are interested in such a state when the problem that exists resolves by itself, or it does not require any solution at all. When we think about the valve cap issue this way the solution becomes crystal clear.

How about making the valve cap to notify us by itself that it was stolen? One way to achieve it is to have a valve cap that has a different structure, like shape or color. Well, indeed changing the color of the cap was what I did. I took a BIC wite-out and simply colored the cap in white color! Yep. That solved the issue, since even if the cap was stolen I’d see it right away on another bike.

This approach solved the issue and also made the valve easier to spot when I needed to inflate the tire.

Well, thank you for reading until the end and stay tuned for the next blog post in the series.

Take care.

Inventions are everywhere. You just need to look carefully.

From idea to invention by an algorithm

I think I’ve exhausted the nutrition and fasting topics, so I decided to move on to something else like creativity and inventions. You’ve heard it right, inventions. I’ve already posted a number of posts on this subject before. It happened that around 2004 I stumbled upon an article by Pavel Amnuel about how to come up with sci-fi ideas using an algorithm and since then I was hooked. Through Pavel Amnuel I learned about Genrikh Artshuller a soviet sci-fi writer and an inventor of the Theory of Inventive Problem Solving (aka TRIZ in Russian). Later I met with Pavel Amnuel who was a sci-fi writer and astrophysicist himself. Reading articles and books at altshuller.ru website I came alone Searing Mind short sci-fi story that Altshuler wrote. So I decided to translate it into Hebrew which I did together with Israela Beker. Through this work I came to know Vladimir Petrov who was an inventor and an engineer and also Altshuller’s close student as Pavel Amnuel was.

Everyone can be an inventor

Since then, I am back and forth with regard to TRIZ having read a number of books that Genrikh Altshuller wrote and trying to use his approach in a real life. So I thought to myself that I could write a series of posts where I’d describe how it was possible to use TRIZ methods in solving every day’s problems. How it is possible to approach various issues that each one of us face in everyday life. As one author wrote all that we see around us that was artificially made was once a one’s person idea. And it’s correct. Anything from houses, furniture, cars, computers didn’t exist and had to be invented. Actually, almost everything that we deal with on a daily basis which is a non-leaving matter was created by humans.

What I intend to write?

So there you have it a post that is dedicated to looking at a problem and how it was solved using TRIZ methodology. By the way what I refer to as a problem is actually defined as a contradiction in TRIZ. Contradiction lies at the heart of TRIZ, since its machinery is useful only when contradiction found and clearly reviewed to be later resolved. By the way, invention defined in TRIZ as a resolution of a contradiction. So if there was no contradiction there was no invention either by TRIZ definition. This makes it much more easier to decern among patents what is actual genuine invention in comparison to being a clone or a modification of an existing invention.

Next post will be such a post as described above. Till then take care.

68 hours fasting results

How did I end up doing it?

Previously I did a 42 hours fast. After that I returned to doing the usual 19 hours intermittent fasting with 5 hours eating window. But I thought to myself that I could do even better and try a longer fast to loss even more body fat as a result. So I tried and finished a longer fast which was scheduled to be 66 hours, but in the end ended up being 68 hours. The fast ended with a big surprise that I’ll discuss later.

Initial setup

Fasting length

From 4:20 PM on Monday, Nov 21th to 12:20 PM on Thursday, Nov 24th.

Fasting progress

Detailed progress

Same information as a graph

Final result

After 63 hours of fasting at 7:20 AM, Nov 24th

A big surprise

The fast has been finished successfully. This time it was more difficult than 42 hours fast. What is funny I did 26 hours more this time, but weight loss was the same as during 42 hours fast.

  • Initial weight was 78.1 kg (172.18 lb), body fat 24.8 %
  • Final weight is 74.4 kg (164.02 lb), body fat 23.4 %

42 hours fasting results

How did I end up doing it?

I am doing Intermittent Fasting for 23 weeks now. Starting from about 18th week my weight loss plateaued and I needed to do something to get it moving. So I recalled that I can try doing extended fasts which are fasts longer than 24 hours. Well, I decided to do 42 hours fast that starts on 6:00 PM and ends after 42 hours on 12:00 PM.

Initial setup

Fasting length

From 5:40 PM on Wednesday, Nov 9th to 11:59 AM on Friday, Nov 17th.

Fasting progress

Detailed progress

Same information as a graph

Final result

After 42 hours of fasting 12:00 PM

weight after 40 hours of fasting

The fast has been finished successfully. Overall feeling is good. Nothing special to report except for crumbling belly feeling yesterday in the evening.

  • Initial weight was 77.2 kg (170.2 lb). Final weight is 74.7 kg (164.7 lb). That’s after drinking a cup of water and a cup of coffee which added about 0.4 kg (0.9 lb) of weight.

Significant weight loss at the very last hours of the fast

Again the same observation

Initial setup

Weight at 14th hour of the fast just before going for a walk/running was 75.8 kg (167.1 lb), body fat 23.9 %.

After walking

After walking/running for 66 minutes on 14th hours of the fast and doing 6.67 km (4.14 mi), weight became 75.3 kg (166 lb), body fat 23.8 %.

Overall weight loss 0.5 kg (1.1 lb), body fat 0.1 %.

Now, after 5 months of measuring weight to fat loss dependency,
Speaking of myself, I know that losing 0.1 % of body fat corresponds to 100 gram (0.22 lb) of fat loss.

Net body fat loss

So net body fat loss is 100 gram (0.22 lb) and the rest of 400 gram is water (sweat, breathing) and possibly energy that went on heating the body, since I walked at 5 degrees centigrade (41 F) with only T-shirt and light jacket on.

Why Calories In equals Calories Out is wrong again

According to tracker calculation below I burned 378 calories, which is 378 / 9 calories in 1 gr of fat = 42 gram of fat loss.

Again, it contradicts what my scale is showing, which means that Calories In = Calories Out theory is wrong. But we knew this already.

Books that literary make you who you are

Intro

There are a number of posts that I wrote about books and how they helps us change our lives and ourselves. The books below literary helped me to change my body composition and shed dozens of pounds of fat that came from eating sugar, sweets, starchy foods and drinking soft drinks, in short, what we call nowadays Ultra Processed Food.

It seems to me they could be helpful to some of you who wants to make a change.

Books on fasting I read and recommend

I sorted the books based on how I liked them the most.

  1. FAST. FEAST. REPEAT by Gin Stephens
  2. The Obesity Code by Jason Fung
  3. The Complete Guide to Fasting by Jason Fung
  4. Why We Get Sick by Benjamin Bikman

  6. Fat Chance by Robert Lustig
  7. The Case Against Sugar by Gary Taubes
  8. The Intermittent Fasting Revolution by Mark Mattson
  9. The Every Other Day Diet by Krista Varady
  10. Delay, Don’t Deny by Gin Stephens (it was her first book on the subject. In comparison to her second this one has more personal info about Gin’s experience with IF)

Books on nutrition that I read, but they were not that easy to make it through

  1. The Case For Keto by Gary Taubes
  2. The Big Fat Surprise by Nina Teicholz
  3. Metabolical by Robert Lustig
  4. Swallow This by Joanna Blythman (I’ve finished only 3/4 of this book. It turned to be quite boring)

Intermittent Fasting isn’t a diet

There is a difference

There is a big difference between Intermittent Fasting (Time-restricted Eating) and a diet (Calorie Restriction).

In the Flipping the Metabolic Switch: Understanding and Applying Health Benefits of Fasting (Obesity, 2018 Feb., 26(2): 254-268) paper by Mark P. Matson et al. they are defined as follows,

  • Intermittent Fasting (IF) – This eating pattern involves fasting for varying periods of time, typically for 12 hours or longer.
  • Calorie Restriction (CR) – This eating pattern involves a continuous reduction in caloric intake without malnutrition.

Your typical diet

During regular diet when caloric intake is restricted a few things happen to your body.

  1. The body tunes down your metabolism. As a consequence you can have a feeling of cold, mood change and feeling of tiredness.
  2. Due to lower Leptin hormone, which signals to the brain that you have not enough stored energy, you start feeling continuous hunger.
  3. While at first you lose some weight (mostly muscle), in the end after struggling with the diet you gain your weight back, but more. After all 99.5 % of diets fail.

As for Intermittent Fasting

While you fast for at least 16 hours, which allows your body to deplete glycogen stored in muscles and liver, your body will switch from using glucose as a main source of energy to using ketones produced by liver from fatty acids (fat).

  1. When this transition happens your body is perfectly happy, there is no feeling of hunger.
  2. Metabolism is actually elevated and you feel good.
  3. There is almost no loss of muscle mass, but a connective tissue. Instead what is lost is the fat that was stored by your body. And if you do resistive training or walking while fasting there will be actually muscle mass gain!

Conclusion

So diet and fasting are complete opposites of one another.

One thing to mention is that it takes time (a number of weeks) for body to get used to fasting.
And even then you still could feel hunger in evenings due to naturally elevated level of the Ghrelin hormone. So it’s not simple, but doable and has such health benefits, not mentioning fat loss, which makes it beneficial in the long run.

Weight loss is very easy when you know how

Online Java Compiler

Processed Food is a blocker for weight loss

When you eat sugary and starchy foods, aka Processed Food your glucose level in the blood is high, as a consequence Insulin hormone level is also high. When it’s high fat is stored.
If you eat more than 3 times a day and have snacks between the meals Insulin will stay high. So fat will continue to accumulate in the body. Fructose in processed food is very harmful too, but it’s for another post, meanwhile check what Dr. Robert Lustig has to say about it.

Solution

Drop Insulin level by constraining when you eat, which is called eating window. I have on average 5 hours eating window and 19 hours of fasting time.

Research shows that having 8 hours eating window could be enough for body to switch to burning stored fat.

My emphasize is on the word could. This is because it’s not enough to follow 8 hours eating window. Because if you do, but continue to eat Processed Food, fasting for 16 hours could be not enough to use all glycogen stored in muscles and liver. If this happens your body won’t switch to burning fat at all.

So weight loss algorithm is simple

  1. Have at most 8 hours eating window and 16 hours of fast time.
  2. Eating sugary and starchy food during eating window prevents you from losing weight during 16 hours fast.
  3. Walking or doing resistance training at the very last hours of the fast, when body switched to using stored fat as energy speeds up the fat loss even more.

Know how and why fasting works

Photo by Sebastian Bill on Unsplash

From time to time I talk to people who started doing Intermittent Fasting with the goal to loss weight, but they don’t know how and why it works. Moreover, they are not even interested to gain this understanding.

I strongly disagree with this approach to Intermittent Fasting. Without such understanding it’s difficult to stick with Intermittent Fasting in the long run because you can lose your motivation very quickly.

Also, without knowing what you are doing you and why fasting works you don’t know what to adjust to keep losing fat when the weight loss plateaus.

Instead strive to understand how and why fasting works by reading books, papers and videos that explain scientific basis of the fasting.


For example,

Mission accomplished. Intermittent Fasting works. End of 20th week.

Mission accomplished, the weight is 75 kg (165.3 lb)!

  • Today is the day when I achieved my initial goal of 75 kg (165.3 lb) of weight. Body fat is at 23.7 %.
  • It is a weight loss of 15.6 kg (34 pounds), since the beginning of fasting on June 13th. It took 20 weeks to get here. From 90.6 kg (200 pounds) -> 75.0 kg today. Hooray.
  • Well, the scale also showed 74.9 kg at first.

Up to date results

This post is a continuation of the posts where I wrote about my progress following Intermittent Fasting eating regimen. I remind you that my end goal is a body fat of 20% and later 15%. Today I will provide a status update at the end of the 20th week.

This week I had a flexible eating window, which on average was 5 hours long. And on average I ate two meals in that eating window.

My current weight as of 2022-10-29 is 75 kg (165.3 lb) and body fat 23.7 %.

  • Weight loss so far: 34 pounds (15.6 kg)
  • Body fat loss so far: about 6.3 %

Legend

  • Fast Hours stands for how many hours I do not eat anything except for drinking water, black coffee or tea (no milk or sugar).
  • Eating window hours stands for the hours where I have two meals. I have no snacks between meals.

Same information as a chart

Detailed weekly regimen

  • Here come this week statistics. As you can see weight fluctuates during the week, which is expected.
  • What’s important that week over week there is a tendency for weight to decrease.
