I can't tell if you are being sarcastic or agreeing or not. Usually your comments are good so I am going to believe you are sincere here. Somewhat related I am one of those people who needs to make a change as I get >1000 calories from soda a day. I did quit years ago (just cold turkey) and after the initial headaches and tiredness the biggest change I saw was that I was constantly hungry. Much like quitting smoking…

I'm not sure why you would think the response was sarcastic. Coke having sugar is NOT the issue. Drinking literally liters of it each day is certainly the issue. On top of a normal diet all those extra calories are bound to be a problem.

Now it seems silly but while I was going through the thread many responses had something worded similarly. After reading so many of those comments I was probably primed to see negativity everywhere.

eg. It's not THIS it's THAT. (It's not sugar, it's sugar in excess.)

Week old accounts with no prior comments shouldn't be allowed to use hot button words like "crackpot". They should probably include IP addresses in their comments as well.

I... What? Are you really attempting to imply that having low account age on Hacker News is a sign of incompetence/inappropriateness of opinion? Am I really reading this on a website based around people of all ages doing startups ? I mean I'm just not getting the tone of your comment. It sounds elitist, demeaning, belittling and callous. In addition, your "cutting your teeth" approach is absolute bull. You don't want…

People frequently create new accounts to troll or astroturf.

Sugar makes you feel like you're starving. You get sleepy at the peak, "starving" at the trough... like a repeating sine wave. Leads to overeating.

It causes people to lack discipline in what they eat. That's really the issue here. Sugar isn't some poison and it is not a magical 10x the normal calorie. People who eat a lot of sugar are usually still eating a lot of everything else. All those calories add up and lead to weight problems. The first thing to losing weight is to get serious about how much you are eating. Write it all down. People tell me all the time…

It's not really about discipline. If you're "starving" (low blood sugar), you eat big to stop that feeling. There's few people who can will themselves to suffer instead, and really why should they?

Better to avoid the problem entirely in the first place. If you don't feel hungry (stable blood sugar) eating becomes a moot point/routine task.

But who eats sugar to get full? I (and everyone I know) eat sweets after a meal, or because I see them, not because I expect to sate my hunger with it.

As mentioned, there is a lot of sugar hidden in processed foods. Also, a plate of pasta is about the same as far as the body is concerned, just a bit slower on the uptake.

> Dietary fat is what is primarily stored and leads to weight gain during caloric excess Do you have a source for this? The sources [1], [4] you quoted don't seem to say that, at least in a way I could understand.

I could have posted a better reference for that claim, but I was actually very busy when I wrote that. This article by the same author (Lyle Mcdonald, a revered expert on nutrition) clears up that point very well: http://www.bodyrecomposition.com/fat-loss/how-we-get-fat.htm...

So your reference is a guy posting stuff on a blog? Well, here's a counter for you: I've lost 7 kgs on a ketogenic (low carb, high fat) diet. I eat as much as I want until I feel full. And according to body measurement scans, I lost mostly visceral fat and almost no muscle, which is amazing.

Yeah, try telling me you get fat from eating proteins and fat.

Diabetics know better than anyone that dietary sugar is not the only food that can increase blood sugar. Rice cakes have no sugar in them at all, for instance, but have a higher glycemic index than chocolate cake.

Dietary sugar intact/dietary carb intake - at the end of the day, it turns into sugar

But that's not what the article is about. It a about dietary sugar--sucrose and fructose specifically.

And my point is that (aside from glycation damage), blood sugar is a symptom of disease, not a cause of disease.

If only we could figure out a way to not eat foods that increase the amount of sugar in our blood....

Did you completely ignore the comment you were replying to?

What exactly is self-parodying about a "keto-adapted" lifestyle? Rice and bananas cause some of the same effects of sugar on the body. Some people can tolerate this and others can't.

The willing ignorance of East Asia is part of it, but it's more that a lot of the keto diets I've seen draw people in with tirades against refined sugar and starch, yet it ends up with the dieters counting the carbs in their lettuce to maintain their ketosis. How do we get from Coca-Cola being evil to ketosis being necessary? It's a false dichotomy and as crazy to me as 0% fat yoghurt, but people only seem to respond…

Misrepresenting much? We don't count carbs in lettuce. We generally don't count carbs at all. We just stick to eating lots of above ground vegetables, lots of fat, and only slightly increased levels of protein compared to a regular "balanced" diet.

Oh, and we avoid refined sugar for the plague it is.

But it might work differently in your part of the world.

On a recent BBC Horizon, two identical twins went for a month on two separate diets. One of the twins ate a high carb low fat diet, the other did the reverse. By the end of the experiment the one with the worse metabolical and biological outcomes was the twin on the high fat low carb diet. In fact the doctors told him to stop as he was becoming pre-diabetic. link to bbc programme: http://www.bbc.co.uk/programmes/b03t…

The doctors were uneducated, he was not at all becoming pre-diabetic.

I am not a nutritionist or a biochemist, but as a guy with an old BS Chem and a general knowledge, it does not surprise me to hear (again) that we are not all bomb calorimeters. We have long known that our metabolic pathways are neither uniform nor universal. There is no surprise there. When you eat fat, carbohydrate, or cellulose, different things happen.

Thus, I think the extreme "calories is calories" argument is anti-scientific.

Given the real complexity, I personally favor a varied and omnivorous diet, avoiding things both unnatural in their manufacture but also unnatural in their availability. A diet high in sugar is not natural. It would be very surprising if evolution and the evolution of our accompanying microbiome prepared us for it.
