Newbie help please

The problem is that grinding or blending mechanically destroys fibre, turning it into digestible carbohydrate. So the shakes may be more carb-laden than the OP is calculating.

(Joey) #7

I suspect you’re talking about a “serving” as opposed to 100 grams of nuts, as the OP indicates. Our canister of mixed nuts: 100g would easily get you to 30g carbs gross (about 24g net).

But make sure you don’t chew them… like a blender, you’ll be breaking down those carbs from their fiber casing :wink:

You illustrate one reason why the “laws” of thermodynamics don’t work on humans: these are in a closed system, but humans are open systems. That is, eat some blueberries sometime, then look at your poop when you poop them out. Note some relatively fully-formed blueberries? If so, those are calories you didn’t get from those.

(Joey) #9

I don’t imagine the laws of thermodynamics require looking at one’s poop. I may be mistaken as my physics classes were old school.

Not to mention that, even if the human body were a closed system, the Laws of Thermodynamics say nothing about the direction of causality. Gary Taubes likes to point out that teenagers eat a positive energy balance, but no one ever claims that they grow because of that. Rather, we all recognise that teenagers have to eat a positive energy balance in order to sustain the growth their hormones are calling for. And this same logic underlies the ketogenic diet. We eat at a caloric deficit, even while we are eating to satiety, because our hormones have our body in fat-burning mode instead of fat-storing mode. The hormonal model of food partitioning yields a lot more success than “eat less, move more” ever did.

Thermodynamics does not concern human beings. The first mistake we made was to assume it did.

I think this is where Dr. Bikman goes into some detail about this, towards the end I think:

I had to convert it to audio and put it into my podcast player.

(Joey) #12

I get your larger point, and no quibbling here, but I thought the laws of physics affected everyone. Humans don’t get a pass.

@Kram2022 Mark, have we manger to totally co fuse you yet? Feel free to ask specific questions.

Of course they affect people, as well as the rest of the universe. But it’s not as simple as people seem to think. For example, living things can be described as islands of negative entropy, even though they increase the entropy of the universe as a whole. Nick Lane discusses this in some of his lectures on the origins of life. Look at his lectures at the Royal Institution and whatever else comes up on YouTube.

(Joey) #15

Okay, my confidence in physics of the universe has been expanded. :wink:

(Robin) #16

Ya’ll just make me go cross eyed… negative entropy?! Oh my brain…

Some folks don’t produce ketones as much as other folks, even if eating and exercising the same. Seems there may be a genetic component. The highest blood measure I’ve ever had is 0.4.

The 2 brands of unsweetened almond milk I used to drink are 0.3 grams per 100 mls. So it depends on the almond milk.

Anyone have any idea why protein can have a big effect on circulating ketone levels (and therefore ketone production?)? I know there is a lot of talk about gluconeogenesis being demand driven, but I think there’s more to protein synthesis than this. I remember listening to a long term carnivore on youtube saying she wanted to increase her ketone levels to get into the “nutritional ketosis” range so had to cut down her protein.

I don’t understand the mechanism, but this is the reason Dr. Phinney gives for recommending protein in the range of 1.0-1.5 g/kg of lean body mass. On the other hand, there are experts who recommend much larger amounts of protein, and Ted Naiman claims that “there is no such thing as too much protein.” Yet people on a carnivore diet eat a lot of protein and carnivore ketone levels are notoriously low.

The issue is what ketones mean. In one sense, they are an indication that we are in fat-burning mode, because the presence of circulating ketones is a guarantee that insulin is low enough. In another sense, though, the ketones are beneficial not simply as fuel, but they also have epigenetic signaling value. And if one has insulin resistance of the brain, or some other brain condition that benefits from ketones, then maintaining a high level of circulating ketones can be really important.

Another issue is the amount of protein we lose to deamination. The body needs a supply of nitrogen for various purposes, and that nitrogen has to come from amino acids. There is a certain minimum daily nitrogen loss, which is why protein is required in our diet. If we don’t get it in our food, the body starts using muscle proteins as a source of this nitrogen. Nitrogen loss is highly variable from individual to individual, which is perhaps why there is so much debate over how much protein is enough, and how much is too much.

You lost me on the thermodynamics topic!!

Here is the list of nutritional info Ive developed from the food labels and which Im using as a guide (as I didnt know what was typically contained prior to this exercise!)

Welcome to the forum Mark! Yes, I was horrified when I realized how carb heavy my previous way of eating was. Not that I knew how bad it was for me at the time, as far as insulin production and resistance and metabolic syndrome goes, or that it kept me permanently “hungry”.

What are your thoughts on peoples’ responses to what you’re currently eating?

(Robin) #21

My only input is that I believe it helps to only look at total carbs, not net. I don’t always trust labeling. In fact, I used to round up, so I knew for a fact that was under that 20g.

That’s just me tho.

Hi again Mark, have a look at the ingredients in the red thai curry paste. The carbs in it may fit in with your macros but I’m betting it is full of sugar to have 13.6 grams of carbs in it. Peas and corn are also full of sugar. You may want to look at getting more of your carbs from green leafy veg and cruciferous veg, rather than “sugary” veg. They have a better nutritional profile and won’t spike insulin in the same way more complex and/or fibery carbs do. It’s a journey tho, we all start out where we start out, and change things as we go along. Or change nothing if what we’re doing is working for us. The most important thing is we start! How are you finding it so far?

(Mark) #23

I checked the label of the curry paste and of the 13.6g carb there are 3g sugar (22%). is this considered high?

I wasnt aware of the sugary content of corn and snow pea so will limit my intake.

Im actually really into roasted broccoli, cauli and brussel sprouts which I wouldnt have believed had you told me this 6 mths ago!!

(Mark) #24

I’m surprisingly quite comfortable on my new diet, I guess it wasn’t an instant change but I not missing potatoes, chips, cakes, pies, biscuits, milk, chocolate, carrots, etc.

(Megan) #25

What else is in it?
