I would be cautious to make health related reading recommendations where the book comes from 1922 and was on a reading list of a man who was rejecting science based medication for his serious sickness until it was too late.

Good point. The problem is that Steve Jobs ignored Ehret’s concept of a “transition diet,” and became taken with the idea of being a fruit-only eater right away.

I thought the problem was that he ignored getting treated for cancer and died?

Anecdotally what’s helped me get through the initial crappy feeling of cutting carbs is to eat more fat / protein and stay plenty hydrated. (Plus plenty of sleep.)

I become an asshole when I've cut most or all carbs. I don't know how to push through that.

Embrace it. Anger and hate burn more calories.

Fitting to see this during this month, as it is currently the holy month of Ramandan for Muslims, who fast from sunrise to sunset for 30 days.

I'm not sure that qualifies as a fast by metabolic standards. Most people fast for 8+ hours every day. By the paper's definition, it's more like time restricted eating.

I've had serious weight issues for my whole life, primarily due to my love of chocolate. As I approached 400 pounds, I took a hard look at myself and decided to make a change. For the past month (29 days now) I've been doing alternate-day fasting* where I eat about 2000-2500kcal on eat days and cap myself at about 100kcal of half-and-half with coffee on fast days (gotta get that joe). While a lot of it is no doubt no…

I just listened to The Obesity Code by Jason Fung and my mind is kinda blown. Everyone you've said matches what the book covers. The takeaway points are: - Raised insulin is the key driver in weight by preventing the burning of fat and triggers the storage to fat. Insulin is the hormone that tells allows cells to absorb glucose - Type 2 diabetes is caused by insulin resistance, which happens over years of prolonged p…

> Sugars and carbohydrates do not trigger the hormone that says we're full when compared

It's important to note the difference between refined sugars (candy) and natural sugars (fruits). Refined sugars are basically fructose (hello High Fructose Corn Syrup).

Refined sugars -- super hella bad.

When you eat the refined sugars, your liver actually traps the ATP, blocking the pathway to the brain, making you still feel hungry.

Sounds great, but is this compatible with: - bodybuilding - 20 miles daily commute by bicycle - intellectually intense work, e.g. hackathons ?

Lots of people do Ramadan while bodybuilding, playing international level soccer (football) while fasted including no water.

That's not really fasting in a metabolic sense, though. More like time restricted eating.

seems to be becoming more and more “scientifically” clear that brains run better on ketones, and burning fat is cleaner for the body

Wait I might have to dig up the sources. But it is generally accepted in the “Keto sphere” that the brain runs on glucose. Even in ketosis the body creates some glucose for this purpose.

kcal is 1000 calories.

Yes, but the body needs 2000-2500 kcal per day, not cal.

For all intents and purposes, when someone says cal they mean kcal. A single actual cal is so ridiculously small it might as well be irrelevant.

sucrose (white refined sugar) is half fructose, half glucose

High Fructose Corn Syrup has a variable amount of fructose, but is usually similar to cane sugar because it is used as a substitute.
