But zero crashes, monitored by finger stick blood glucose. Crazy stuff, for someone who has them all the time.

Not discounting people's experiences, but trying to suss out the science here. If you were, for example, to inject sugar directly into someone's blood stream would the result be fatigue every time?

It seems to me that there's more involved in this. In my experience (more anecdata!) I'm able to eat anything in the morning. Giant bolus of carbs and sugar, and I feel great. That same meal in the afternoon will give me such a fatigue that I need to lay down.

Clearly there's some other factor at play for me in the function whos result is fatigue.

FATIGUE_LEVEL = CARB_GRAMS * (HOUR_OF_DAY / 24)

For many people, it may not be, I can only speak for myself. There's another thing, called 'idiopathic postprandial syndrome' which is essentially the symptoms above, but without actual low blood sugar (<60mg/dl), which some people think is another form of insulin resistance, where your blood sugar is normal but your body "wants" more sugar in the blood.

Talking with endocrinologist, they say that the insulin sensitivity for most people is much higher in the AM and daytime than at night, so it makes sense that you might have more problems in the afternoon, but you should probably talk to a doctor rather than taking my word for it!

It's often difficult (in the US at least) to get primary care and endocrinologists to take you seriously if you are not actually dying of diabetes or passing out from low blood sugar - this is where dipping into the realm of concierge medicine can be helpful, or at least, it has been for me. They are often much more willing to investigate thoroughly.

Missed this the first time around. They do this, for research, it's called a glucose clamp test.

Unfortunately it's almost impossible to find someone willing to administer it to you. It's an outpatient hospital procedure lasting a number of hours, and almost no insurance would cover it, as far as I am aware.

Responses are by readers, so take with a pinch of salt

What? That is quite a boring and obvious observation because your insulin sensitivity is much higher in the morning.

I know 2 T1 diabetics, and both never touch potatoes because of the GI.

Can I ask how you deal with your reactive hypoglycemia? I switched to keto a long time ago, which took me from having hypos multiple times a day to never. But often in late afternoon I start feeling some mild hypo symptoms, even though my blood glucose is stable.

Not only did you boil the potato, but you pre-chewed it too. Mashed potato is about as close as you can get to refined potato (potato flour). What you've created is easily digestable amylopectin - pre-chewed, already gelatinized and suspension with water. The amylase in your saliva can mix extremely well with mashed potatoes, and within minutes that amylopectin will be available as glucose. Maybe you mix in a little fat with butter or oil, but probably not much.

Vs. more or less any other potato cooking method. Even though the starch will have gelatinized with the water present in the potatoe, the potato's structure is more intact than boiling & mashing. Even after chewing the starch is not as well mixed with water, and this will take longer to digest.

We don't eat much mash in our house.

But really we are talking about two different things: GI and satiety. Yes potatoes are high GI. It would follow that they will spike your blood sugar. No claims have been made to the contrary.

Satiety is about how full you will feel per calorie eaten of that food. Multiple factors contribute to satiety. Specifically boiled potatoes score super high on the satiety index.

Not mashed potatoes. Not french fries, potatoes gratin, etc.

The topic is only tangentially related to GI.

Don't mean to be cranky here but I was hoping people would talk about the article, the underlying concept (satiety), and the research, instead of going off on lengthy discussions about quasi-related personal anecdotes.

And that's where GI comes in - high GI foods cause blood sugar spikes, and the crash will make you feel hungry again.

Pasta is a good example - it feels very satiating at the time, but the feeling doesn't last long.

I tried keto but it was difficult to get the variety, especially (as you say) when you're intensely craving sugar. It obviously solved the problem but was really challenging to continue, so I only lasted a couple weeks.

I don't understand the motivation to make such a guarantee. It's as though you assume there are many people on HN who have never tried eating two eggs in the same meal. Do you maybe live in a place where eggs are rare (or not commonly eaten)?

(For what it's worth, my personal experience matches that of others here: two eggs would be a comically small breakfast.)

More interesting to me is why someone would phrase it as a guarantee even if it were true. It suggests that the reader likely hasn't tried it, and would be surprised to discover the result.

Yeah no one likes your humble brags about how little you eat and feel JUST GREAT. You're probably worse for it.

I'm 5'11", ~170 lbs and rather lazy right now, running ~15 miles a week and a couple light lifting sessions because I'm busy. I eat 2500 calories a day and maintain just fine.

I just ate 1200 calories at dinner, no problem, so I'm going to try real hard not to feel judged by you!

I just wonder do any of these people actually move? Apologies if you're less-than-abled but good lord, if you're not and you're surviving on so few calories, I just wonder if you're moving enough to actually be healthy?? Thin !== healthy, necessarily.

What a patently absurd claim. Your anecdata is not evidence.

If your usual breakfast is pretty big and you tried to switch then you'd definitely start to get pangs of hunger earlier than you usually would. But after a while, your body would adjust and you'd be fine for longer and longer (really until whenever you usually ate your next meal). It's the reason why intermittent fasting or "one-meal-a-day" sucks the first couple of weeks you try it.

I'm not recommending one way or the other. Personally, I wouldn't eat just 2 eggs for breakfast because it sounds like a boring breakfast (at least throw it on some toast with some hot sauce). But it's certainly plausible that 2 eggs for breakfast would satiate most folks after they got through the initial growing pains.

When I go out for breakfast I will often have two eggs...and a couple of big pieces of toast, mushrooms, hash browns, spinach etc. I have great difficulty believing that two eggs alone would be sufficient.

Fast forward to today and while I would agree that just two eggs would be boring, add in two slices of bacon to cook the eggs in as well as some nice cheese, scramble it all and there's the lunch I'll have after not having had any breakfast at all and having had that, I probably won't be hungry again until way past previous dinner times.

This is after getting my gut back in order, away from craving sugary meal after sugary meal after carb/sugary meal to not having more than 20g of carbs per day (i.e. what they call "Keto diet"). I totally eat carbs again nowadays but usually eat no breakfast and eat way less carbs than I used to. One thing I noticed is that having a "low fat meal" for breakfast (e.g. white toast w/ just jam) means I am usually hungry again before lunch already. What helped on Keto was basically just eating whenever I was "hungry" but just not eating anything with carbs. I used cheese for it. Whenever I "got an appetite", eat some slices of cheese. No counting of calories. Feel "hungry"? Eat cheese! Lost lots of weight after a short period of time on that. The cravings just went away. It's amazing how little calories you actually get from all that fat and protein but it fills you right up. Of course this only works well if you have some fat to burn (my totally non-scientific reasoning is that your body just figures out that it doesn't have to make you find food and can just use the stores. Which means you better have those fat stores on you and please do make sure to eat enough veggies and nuts for your vitamins and minerals - you get the 20g of carbs just incidentally from the veggies, so definitely nothing with flour will go in you) I don't do Keto any longer and I can now maintain weight instead of loosing it :)

I pretty much never get hungry.

I eat because I’d die and I can only enjoy food having consumed massive doses of thc.

I wish Soylent was more trustworthy or the jetsons pill was real.

It means I can lose weight very easily but combined with severe adhd before I was married I was often in trouble and hospitalized a couple times. Now my wife keeps an eye on me to make sure I eat at least dinner, and Apple Watch reminds me to eat and drink during the work day.

Largely: Salads and roasted veggies like sweet potatoes, broccoli, radishes, carrots, squash. Fruits like apples, grapes, blueberries, strawberries.

The low calorie density foods helped make it so I really wasn't hungry.

For example, I've done the fast mimicking diet twice in the past couple of months - a little bit ineptly at points (always plan properly!) - which left me feeling very hungry. Certainly, by the last day of each, I was planning what I'd eat the next day in great detail and anticipation.

The lasting feeling it left (aside from the obvious health benefits) was to be reminded of what real hunger is like, not the semi-boredom, semi-distracting-itch kind that makes me nip to the fridge for a snack. That is very tolerable to me now.

The big breakfast is called a farmers mreakfat for a reason.

That's not what satiety means (at least in this context), right?

I'm reading OP's definition as "you'll eat less [calories] per sitting because you'll feel satiated more quickly", rather than your "your feeling of non-hunger will last longer".

The two seem pretty orthogonal definitions to me.

What am I missing?

I usually eat 3 scrambled eggs when I have them for breakfast. Lunch can't come soon enough afterwards. I think my record is 7 scrambled eggs. I'm sure I had normal lunch that day.

Should be good until 2-3 in the afternoon, at least in my experience.

Overnight oats are great.

EDIT: Wait... uncooked!?

substitute yogurt instead of milk for big increase in protein!

Makes sense that this diet wouldn't work for you - but I think using this argument is sort of like arguing that peanuts are unhealthy because some people are allergic to them.

Fun Fact: You can let your potatoes cool down, and then re-heat them, to significantly lower the glycemic impact.

Tried that. Two eggs and a piece of toast will get me easily to lunch. Four eggs will get me an hour or so, despite having more calories.

My observation was simply that research exists which substantiates this counterintuitive idea (quite a bit of it I believe, the satiety index has been around since 1995).

I'm sure it would spark an interesting discussion if someone had time to dive into the research and the studies.

http://www.mendosa.com/satiety.htm gives an overview and mentions a few of the studies.

As an aside, this potato diet supposedly allows salt and oil - which is all you need to make french fries. French fries did not score well on the satiety index.

Boiled potatoes did.

I physically can't eat any more than 3 eggs because I'd feel completely full.

Maybe I'm twenty kilos heavier than you, exercise more than you, have a bigger appetite than you. Maybe a tape-worm ;) My post, along with many others that have replied to you seem to have done so to challenge your guarantee.

https://www.pcrm.org/news/health-nutrition/egg-consumption-i...

"The authors note results from a recent meta-analysis and data from the Physicians' Health Study and Women’s Health Study showed an increased risk for diabetes of up to 77% with seven or more eggs consumed per week."

"When egg prices rose in the spring of 1966 and Agriculture Secretary Orville Freeman told him that not much could be done, Johnson had the Surgeon General issue alerts as to the hazards of cholesterol in eggs."

There's actually no healthier food than eggs

"Compared with group 1 (30·7 %, low baseline intake and slight increase), both group 2 (62·2 %, medium baseline intake and increase) and group 3 (7·1 %, high baseline intake and decrease) were associated with an increased OR for diabetes. The results suggested that higher egg consumption was positively associated with the risk of diabetes in Chinese adults."

Here's the publication: https://pubmed.ncbi.nlm.nih.gov/33028452/

For me personally, it feels like you're having a panic attack, you get ravenously hungry and eat anything in sight, tremors and heart palpitations, confusion, irritability, dizziness. No fun at all. Thankfully not life threatening though, at least the "normal" kind.
