How do (some) people eat high carb? Genetics? Something else?

(Bob M) #1

I injured my back this weekend, so I’m going to a new (for me) chiropractor. He is tall and thin. Gave me a list of his favorite restaurants: pizza; sushi; Italian; Italian, etc. Most recommended foods are high carb, with one being meat-based.

Meanwhile, I have been using a CGM (continuous glucose monitor). Went to dinner and the drink I had was slightly sweet, so I’m assuming it had high carbs. The dinner was basically keto, though. I did have a few spoonfuls of refried beans + rice, at the end of the meal. Not too bad, a high of 133.

Then went to get ice cream because the wife and I were alone, hit 152, so quite high. Went home, and was STARVING. Every time I eat high carb, even for something like ice cream that is also high fat, I’m starving. I had to eat a small keto mousse (about 3 ounces) made with 100% cacao, coconut, allulose.

This is reason I stopped eating higher carb, because I’m always hungry after eating high carb.

How do people eat high carb? Do they have some type of feedback system that still works/always worked to tell them to stop eating?

Mine is broken or I never had it or it never worked well, because if I eat high carb, I want more. Nothing is telling me “you’re full” when I’m eating high carb.

Am I broken? Is the other person “normal”? Or just gifted? .

I’ll vote for genetics is the answer.

My mom had what they called “adult onset diabetes” when I was 10 or younger. As I’m sure you know, they stopped calling it that when children started getting diagnosed with it. Mom did well, making it to 91, though still overweight and still on medication. My brother was diagnosed with type 2 as an adult, but I’ll guess when he was in his early 30s. I’m the one out of three that has never been diagnosed but after going on Atkins in the late '70s (before I was 30) and starting “lifelong fitness” stuff like jogging, I’ve been on the low carb side almost constantly. It just always seemed like it wasn’t low enough no matter what I did because no matter what I did my weight kept creeping up. I think all three of us have a sweet tooth. I still deal with that.

In the late '70s, I worked with a guy who would bring a big, paper grocery bag (remember those?) for lunch every day, his lunches looked way, way bigger than mine. We’d all joke about him being able to eat that much and not roll down the aisles instead of walking.

I say the other person is gifted, but they think they’re totally normal and rest of us have no willpower.

I ate high carb freely in my youth and early adulthood. I began to gain weight in my thirties. I was slowly upping my insulin resistance without knowing it.

Most people will have this happen and the weight gain is only one of the variety of things that can happen. Type 3 diabetes being the thing that comes to mind (dementia).

And yet there are people that avoid both despite a high carb diet. I have a BIL like that. Thin, active and mentally all there and now 80. Here is where I think a thing happens and it’s about epigenetics. The gestational period when mother and fetus are sharing a lot of things including genetic material. The mother has already some level of metabolic disease induced by diet and passes it along to her fetus.

Sounds simplistic because I don’t really understand all of the intricacies of epigenetics but in my simplistic way, think this is a possible explanation.

@CFLBob Yeah, my vote is also genetics, because I’ve exercised all my life yet still gained weight. Sometimes while exercising a ton. I think some people have a functioning “feedback” system that tells them to stop eating, even when eating carbs. Not much else makes sense to me, though I do believe I ruined or at least partially ruined my “feedback” system, probably with super high carb days (beer, pizza, ice cream).

@clackley I have heard multiple people (including Gary Taubes?) saying that what happens in the womb could be affecting our kids (or have affected me)? Much of my extended family was overweight, but we also ate super high carb (and higher fat), so it’s hard to tell. In my extended family, I only know a few people who were thin and able to maintain that. Though smoking is another factor thrown in, as some of the people who were/are thin also smoked.

I think it’s probably related to something like this:

This comes from a study, but I got it from here: https://www.healthmaxim.com/posts/a-guide-for-people-without-diabetes/

I’m assuming I’m the person who eats (all of the) pasta and gets hungry and wants more; whereas my chiropractor eats pasta and is totally full and doesn’t eat the whole plate of pasta.

Wow!

That plot of blood sugar vs. time is really remarkable.

I have some things that I eat from time to time that have more carbs than pure carnivore food, but nothing I think of as being high carb. I make tomato sauce based beef marinara for one example, or unsweetened yogurt, and since I don’t have a CGM, maybe I should do the old standard way. Fast for a few hours, have a sample and see what it does by sticking a finger and measuring a few times with my Contour Next.

EDIT TO ADD: I forgot to mention that I don’t feel like I eat more, and since in a couple of quarts of this beef stew, what you get in one bowl is practically impossible to figure out. It depends on how many carbs or calories you’re getting depending on how much sauce, or how many chunks of beef you eat, and so on.

Genetics surely has a role. My SO is a high-carber, he simply gets satiated by carbs very well. His satiation is almost all about calories, it’s crazy. He still needs protein, obviously but he is very health-conscious and anyway, desires protein so no way he doesn’t get it.
I am different, I need the right macros and even the right items (timing matters too). High-carb doesn’t suit me but I am very satiated on high-carb too, I just eat too much. I can’t get a stop sign without enough calories AND protein and carbs may interfere so I need more calories (or don’t need, I just eat it). If I eat thousands of kilocalories so my meal is big even in my eyes but my protein is low, I need more food. If not right then, later. But it’s usually right then. Sure, my SO needs his protein too but a super carby breakfast (well, fruity oatmeal. it’s the carbiest he can do for breakfast) keeps him satiated for 6-8 hours if it’s his normal breakfast size (he always eats around the same amount of calories with wildly different macros and everything seems to work the same. I am very sure pure sugar wouldn’t work but he couldn’t eat in such an extreme way if he wanted).

Gaining fat is another matter. My SO very easily gains fat so he is disciplined and very active. Low-carb makes things worse for him. Meanwhile I never could lose fat on high-carb by my own will, low-carb is helpful in various ways.

If it’s not nutritious enough, it makes sense to me, the body needs more.
If it’s a perfect usual meal + carbs and it’s lacking despite the extra food, yeah, I know that, stupid carbs interfere. They aren’t for all of us. I probably can pull it off now if it’s together with my fatty protein and not too excessive. I can’t end my meal with a bunch of carbs though. It doesn’t even feel right. And it’s perfectly fine, my body telling me it doesn’t like that style.

How people during human history (without able to choose) managed high-carb though… Even people like me? Poor souls. Many had super low protein from my viewpoint too. Could I get used to that?
At least I have no allergies or sensitivities. High-carb just doesn’t work so well.

My whole life I can it buckets of carbs everyday never put weight on was always very active. In my work and exercise. Carnivore now works great.

As an RDN at Kior Healthcare, I believe that if your genetics are good and you maintain overall fitness, carbohydrates and wholesome protein foods are generally not difficult to digest. However, for personalized guidance tailored to your body type, it’s always best to consult a professional RDN.

It’s also possible gut biome could have something to do with it. For example, a lot of what is termed fiber carbs that “don’t count” is actually handled further down by gut bacteria. No glucose spike but eventually provides those carbs / calories. If you’re missing those gut bacteria you’re also missing that extra carb load.

You beat me too it. I’m not going to start listing my first hand experiences with high carb food that doesn’t effect ketosis. My armchair view is genetics plays a role, but to a lesser extent.

152 is pretty good after something like Ice Cream! Especially if you returned to baseline pretty quick.

Don’t feel bad, my hunger/satiety is permanently broken as well. Spent the last year on Semaglutide and lots of nicotine gum, and ephedrine to help beat it down. Now just switched from Semaglutide to Tirzepatide since it beats appetite down even more, although not yet sadly. I think I may have to jump way up in dose for that effect, which I’ll be doing this week.

That said, even when my stomach DOES actually give me that full feeling, my brain is still telling me to eat.

Years of strict keto, TKD, CKD, doesn’t matter. I’m always hungry.
